Probe connection
Insert the double plug of the probe into sockets 4 and
5 such that the plug with the white ring contacts
socket 5 (vertical bar).
Note: Contact problems with exposed conductive parts
when using the standard probe with test tip
In order to assure good contact, surface coatings must be
removed from devices under test with special tools at a suit-
able location so that the surface has a metallic shine. The tip
of the test probe is not suitable for scratching away paint, be-
cause this may impair its coating and/or mechanical
strength. The brush probe (Z745G) may be more suitable
than the test probe in certain individual cases.
Measurements at jacks 1 – 2 – 3
Always start with the measurement before contacting
the measuring point. Between jacks 1 and 2, a maxi-
mum of 10 V may be applied. Between jacks 2 and 3,
up to 253 V may be applied.
Attention: Jacks (2) and (3) are short-circuited
during all measurements at the test socket!

when using other probes than those specified above
The cables plugged into the sockets (4 and 5) must be short
circuited for testing with the probe, i.e. by plugging the ends of
the cable together, or via a conductive surface at the device
under test (4-wire measurement).
Remove any corrosion from the device under test.
Data Security
Measurement data, report data and user entries are stored to RAM at the
(P)SI module (accessory), as long as the respective battery supplies the
required amount of voltage.
Save your data to a PC on a regular basis in order to prevent any loss of data
at the (P)SI module. We assume no liability for data loss. We recommend the
following PC programs for data processing and data management:

2 Safety Features and Precautions
This instrument fulfills the requirements of the applicable European and
national EC guidelines. We confirm this with the CE marking. The relevant
declaration of conformity can be obtained from GMC-I Messtechnik
GmbH.
The test instrument has been manufactured and tested in accordance
with the following safety regulations:
IEC 61010-1 / DIN EN 61010-1 / VDE 0411-1, DIN VDE 0404, DIN VDE
0413 Part 2 and 4 and DIN VDE 0104 (Feature F02 or
SECULIFE ST
HV
)
Only when used for its intended purpose, the safety of the user, the test
instrument and the device under test (electrical equipment or electrical
medical devices) is assured.
Read the operating instructions carefully and completely before placing your test
instrument into service, and follow all instructions contained therein. Make sure
that the operating instructions are available to all users of the instrument.
Tests may only be performed by a qualified electrician or under the super-
vision of a qualified electrician. The user must be instructed by a qualified
electrician concerning performance and evaluation of the test.
Note
+
Manufacturers and importers of electrical medical devices must
provide documentation for the performance of maintenance by
trained personnel.
Observe the following safety precautions:
The instrument may only be connected to electrical systems with
230 V/240 V
which conform to the applicable safety regulations (e.g.
IEC 60346, VDE 0100) and are protected with a fuse or circuit breaker
with a maximum rating of 16 A.
Measurements within electrical systems are prohibited.
Be prepared for the occurrence of unexpected voltages at devices
under test (for example, capacitors can be dangerously charged).
Make certain that the measurement cables are in flawless condition,
e.g. no damage to insulation, no interruptions in cables or plugs etc.
When using a probe with coil cable (SK2W):
Grip the test probe firmly, for example after insertion into a jack socket.
Tensioning at the coil cord may otherwise cause the test probe to snap
back resulting in possible injury.
Measurement of Insulation Resistance and Equivalent Leakage Current
This test is performed with a maximum voltage of 500 V, with a current
limit having been set (I < 3.5 mA). However, contacting the terminals
(3 or 2) causes an electric shock which, in turn, may result in accidents.
Leakage Current Measurement
During leakage current measurement it is imperative to ensure that the
device under test is operated at line voltage. Exposed conductive parts
may be charged with hazardous contact voltage during the test and
may consequently not be touched under any circumstances. (There is
a power shutdown as soon as the leakage current is higher than ap-
prox. 10 mA).
Attention!
!
The function test may only be performed after the DUT has
successfully passed the safety test!
Switching loads on and off
When switching the DUT on or off under load it is imperative that you ad-
here to the order indicated below. This helps to prevent excessive wear
and tear of the mains relays at the test instrument.
Before the measurement:
1) DUT: Switch the DUT off at the proprietary switch.
2) SECULIFE ST or SECULIFE ST
HV:
Apply line voltage to the test socket .
3) DUT: Switch on the DUT at the proprietary switch.
After the measurement:
4) DUT: Switch the DUT off at the proprietary switch.
5) SECULIFE ST or SECULIFE ST
HV:
Disconnect the test socket from the line .
The measuring and test instrument may not be used:
If it demonstrates visible damage
With damaged connector cables, measuring cables or patient ports
If it no longer functions properly
After extraordinary stresses due to transport
In such cases, the instrument must be removed from operation and
secured against unintentional use.
10 GMC-I Messtechnik GmbH
Opening of Equipment / Repair
The equipment may be opened only by authorized service personnel to
ensure the safe and correct operation of the equipment and to keep the
warranty valid.
Even original spare parts may be installed only by authorized service per-
sonnel.
In case the equipment was opened by unauthorized personnel, no war-
ranty regarding personal safety, measurement accuracy, conformity with
applicable safety measures or any consequential damage is granted by
the manufacturer.
Meanings of Symbols on the Instrument
The symbols on the instrument have the following meanings:
Warning regarding dangerous electrical voltage
Warning concerning a point of danger
(Attention: observe documentation!)
Test socket

2.1 Notes Regarding the High-Voltage Test
(only Feature F02 or SECULIFE ST
HV)
The KS13 cable set, or similar cable sets, may not be used for the high-voltage
test. The high-voltage test may only be performed directly via the test socket!
Attention!
!
Do not hold the device under test in your hand during testing,
especially when testing safety class II devices.
Make sure that the device under test does not make contact
with any equipment or persons during testing.
Liability Exclusion
In the event of sparkover, PCs operated in proximity to the test instrument may
“crash” resulting in data loss. All data and programs should be suitably backed up
before high-voltage testing is performed, and computers should be shut down if
necessary. A crash may occur even if no RS 232 connection has been established.
The manufacturer of the test instrument assumes no liability for direct or
consequential damage to computers, peripherals or data which occurs
during high-voltage testing.
The manufacturer assumes no liability for defects at the device under test
which result from high-voltage testing. As a rule, defects can only occur at
devices under test which are not in compliance with applicable standards,
which were previously damaged or which have been improperly repaired,
because high-voltage testing is required for type and routine testing by
IEC 61010-1/EN 61010-1 / VDE 0411, part 1, as well as EN 60335,
EN 60601 and EN 60950.

3 Initial Start-Up
3.1 Connection to the Mains (115 V / 230 V, 50 Hz / 60 Hz)
õ Connect the mains plug at the test instrument to the mains power out-
let. The function selector switch can be set to any position.
If a mains outlet (earthing contact outlet) is not available, or if only a
3-phase outlet is available, the adapter socket can be used to connect
the phase conductor, the neutral conductor and the protective con-
ductor. The adapter socket has three permanently attached cables
and is included with the KS13 cable set.
Attention!
!
If connection is not possible via an earthing contact outlet: Shut
down mains power first.
Then connect the cables from the coupling socket to the mains
using pick-off clips in accordance with the diagram.
Disconnection from mains power is only possible with the mains
plug.

3.2 Automatic Recognition of Mains Connection Errors
The test instrument automatically recognizes mains connection errors,
if the conditions in the following table have been fulfilled. The user is
informed of the type of error, and all measuring functions are disabled
in the event of danger.
1)
In SETUP – test sequence – IT system
Attention!
!
If you discover during the protective conductor potential test
that the mains protective conductor is charged with voltage (in ac-
cordance with the two cases mentioned first), you may no longer
perform any measurements with your test instrument. Voltage is ac-
tually present at the exposed earthing contacts of the standard
socket (21) as well and may be dangerous to you. Disconnect
the test instrument from the mains immediately and see to it that
the defect at the mains connection is repaired.
Note
+
Voltage at the electrical system’s protective conductor PE may result in
distorted measurement values during testing for the absence of
voltage, or during leakage voltage measurements.

4.1.2 Automatic Safety Class Selection
Depending upon the type of mains plug or the connection configuration
for the device under test, the test instrument recognizes the respective
safety class and recommends its use for the measurement to be per-
formed.
4.1.3 Manual or Automatic Operating Sequences
Depending upon selections made in the setup menu (selector switch in
the Auto position), the next measurement is started automatically after the
current measurement has been completed, or can only be started after
manual acknowledgement. The integrated online instructions are ade-
quate for most tests and measurements. However, the contents of these
operating instructions should nevertheless be read and observed.
4.2 Online Help
Online help can be queried and displayed at the LCD for all measuring
and test functions, and for almost all settings. Schematic diagrams which
illustrate proper connection of devices under test to the test instrument
can be displayed as well.

5 Classification of Devices Under Test
5.1 Safety Classes
Devices assigned to all of the following safety classes are equipped with
basic insulation, and provide for protection against electrical shock by
means of various additional precautions as well.
Safety Class I Devices
Exposed, conductive parts are connected to the protective conductor so
that they are not charged with voltage if the basic insulation should fail.
Safety Class II Devices
These devices are equipped with double insulation or reinforced insula-
tion.
Safety Class III Devices
and Devices with Internal Power Supply
These devices are powered with Safety Extra Low Voltage (SELV). Beyond
this, no voltages are generated which exceed SELV. These devices may
not be connected to the mains. They may only be connected to the test
instrument at jacks 1 through 3.
Note: The DUT may only be connected to jacks 1 to 3 at the test instru-
ment. It is only possible to perform a visual inspection, a measurement of
the insulation resistance or the supply voltage, see parameter “SC III U
V
on page 39.
Classification Parameter (in the Sequence ... menu)
The test instrument always performs testing in accordance with the strict-
est limit values of the respectively selected safety class. The test is failed if
this limit value is exceeded.
However, higher limit values are allowed for certain devices under test.
If the classification parameter has been activated (= x), the user is asked if
higher limit values are allowable for these devices. If the user responds
with “Yes”, the DUT is reevaluated and the test may be passed.
Devices with Internal Power Supply
Devices with internal power supply are tested like permanently connected
Safety Class II or III devices.
5.2 Application Parts (electrical medical devices)
Type B Application Parts (body)
Devices of this type are suitable for both internal and external patient
applications, except for use in direct proximity to the heart.
These devices provide for adequate protection against shock especially
as regards:
Reliable leakage current
Reliable protective conductor connection if utilized
Devices of the following safety classes are allowable:
I, II, III or devices with internal electrical power supply.
Type BF Application Parts (body float)
Same as type B, but with type F insulated application parts.
Type CF Application Parts (cardiac float)
Devices of this type are suitable for use directly at the heart. The applica-
tion part may not be grounded.
Devices of the following safety classes are allowable:
I, II or devices with internal electrical power supply.

7 Connecting the Device Under Test
õ Connect the DUT in accordance with the schematic diagrams included
in the online help function.
Connection of the DUT to the test instrument depends upon:
The type of device under test:
electrical equipment or not, with or without application parts
The type of connector included with the DUT:
– With plug (“to test socket” parameter), applies to EL1 adapter as well
– Without plug, single or multi-phase connection (“to jacks” parameter)
– No connection to tester (“permanent connection” parameter),
see also chapter 3.1
Whether or not an adapter is used:
– Adapter to socket (customer specific adapter)
– AT3-II S to socket, adapter for devices which are equipped with
5-pole, 16 A CEE plugs
– AT3-III E to socket, adapter for devices which are equipped with
5-pole, 32 A CEE plugs, see AT3-III operating instructions for test
sequence.
The DUT’s safety class (I, II or III)
Note
+
The DUT must be switched on for all tests. Switches, relays,
temperature regulators etc. must all be taken into consideration.
The test instrument automatically recognizes whether or not the DUT is
connected to jacks 1 through 3. The instrument also recognizes whether
or not the DUT has been connected to the test socket. As a default set-
ting, the program sequence assumes that the plug from the DUT has
been connected to the test socket.
Note
+
Safety Class II Devices with Safety Class I Mains Plugs
If the device under test is equipped with a safety class I plug
although it complies with safety class II, safety class I is recog-
nized by the test instrument. If this is the case, switch from safety
class I to safety class II in the initial menu.
If the test instrument is unable to automatically recognize how the DUT
has been connected, the recommended connection setup should be
double checked and determined manually if necessary.
õ Position the cursor at the third line in the start menu for the test se-
quence.
õ A selection of possible connection setups can be displayed by
activating the key.
õ Select the desired connection setup with the cursor and
acknowledge with the key.

age current greater than 15 mA from L/N to PE. This
value should be increased for some DUTs (in particu-
lar high-current consumers), because greater leak-
age currents are present.

9 Measuring Protective Conductor Resistance
Definition
Protective conductor resistance
is the sum of the following
resistances:
Connector cable or device
connector cable resistance
Contact resistance at plug
and terminal connections
Extension cable resistance if
utilized
Resistance is measured:
Between each conductive
part of the housing and the earthing contacts at the mains and the de-
vice plug (if a removable mains connector cable is used), or the protec-
tive conductor terminal for permanently installed devices.
as 4-pole measurement
Between the earthing contacts at the mains plug and the earthing
contacts at the device plug for device connector cables
Between the earthing contacts at the mains plug and the earthing
contacts at the coupling socket for extension cables
Connecting Safety Class I Devices to the Test Socket
When the DUT is connected, resistance is measured between the protec-
tive conductor terminal at the test socket or at the PE jack and the probe
connection at the DUT (contact with conductive parts of the housing).
õ In order to measure protective conductor resistance, contact a
conductive part of the housing with the probe, which is connected to
the protective conductor.
During measurement, the connector cable must only be moved in as far as
it is accessible during repair, modification or testing.
If a change in resistance occurs during the manual test step of the conti-
nuity test, it must be assumed that the protective conductor is damaged,
or that one of the connector contacts is no longer in flawless condition.
Testing Extension Cables
See test sequence in chapter 15.7 on page 46.
Note
+
“Connection of the DUT: SC I/II” is not displayed when the test is
performed individually, but rather only during the automatic test
sequence.
Selecting Test Current and Polarity
Test current amperage (200 mA DC or 10 A AC (Feature G00 or SECULIFE ST) or
200 mA DC, 25 A AC (Feature G01 or SECULIFE ST
HV)) as well as polarity can
both be changed by pressing the or the key.
Testing with 10 A Test Current (Feature G00 or SECULIFE ST)
or 25 A (Feature G01 or SECULIFE ST
HV)
The test has a maximum duration of 30 s (fixed value) if 10 A or 25 A test
current is used. After this time period has elapsed, the last measured
value is frozen and “data hold, measurement stopped” appears at the dis-
play. If the test instrument becomes excessively warm, testing cannot be
repeated until after a waiting period of 1 minute. When testing with 10 A or
25 A, the last measurement can be repeated if the test results in failure.
PE

20 GMC-I Messtechnik GmbH
Combined Testing – Differential Protective Conductor Resistance
Zero balancing is also possible for protective conductor measurement. With
zero balancing, all subsequent measurements are adjusted with an offset
such that 0 Ω is displayed for a selected reference point which is con-
nected to the protective conductor. When test points are contacted with
the probe which are electrically connected to this reference point, differen-
tial resistance ΔR
PE
between the reference point and the contacted test
point is displayed. The mains release key must be activated during
measurement in order to perform zero balancing. Press key
„Store
value“ in order to save the reference and/or correction value. The meas-
sage „Zero point corrected“ concerning the reference value is displayed
during all future measurements.
Attention: It is absolutely essential to delete the reference value after the
reference value has been stored and the test has been performed as it is
taken into account in all future tests. To delete the value, the procedure is
the same as for storage, press key
„Delete value“.

Measurement of Insulation Resistance (equivalent leakage current)
This test is performed with a maximum voltage of 500 V, with a
current limit having been set (I < 3.5 mA). However, contacting
the terminals (3 or 2) causes an electric shock which, in turn,
may result in accidents.
Note
+
All switches at the device under test must be set to the ON
position during measurement of insulation resistance. This also
applies to temperature controlled switches and temperature
regulators.
Measurement must be performed in all program stages for
devices equipped with program controllers.
R-INS
Start measurement.
Nominal voltage is 500 V DC in this
case.
Nominal voltage can be adjusted within
a range of 50 V to 550 V DC.
Note
+
When insulation is first started from the menu, nominal voltage is
always set to 500 V. Open-circuit voltage is always greater than
nominal voltage.

10.2 Equivalent Leakage Current
General
The equivalent leakage current measurement is a method for measuring
protective conductor current (DIN VDE 0701-0702) and/or device leakage
current (IEC 62353 (VDE 0751)).
A high-impedance power supply is connected between the short-cir-
cuited mains terminals and all exposed metal parts of the housing (which
are connected to one another).

Connection Exception for Permanently Installed Safety Class I Devices
Current is measured between the probe, with which the L and N conduc-
tors must be contacted, and the protective conductor terminal PE at the
device under test for permanently installed safety class I devices under
test.
Attention!
!
Disconnect mains power before connecting the test instrument!
õ Remove the mains fuses from the device under test and disconnect
the neutral conductor N inside the device under test.
õ Connect the probe to phase conductor L and neutral conductor N at
the device under test in order to measure equivalent leakage current.
Sequence
Current is displayed during this type of equivalent leakage current
measurement which would flow during leakage current measurement
conducted in accordance with device regulations with nominal voltage.
Leakage current measurement in accordance with the respective device
regulations is usually not possible, because the device would have to be
set up in an electrically isolated fashion, or connected to an earth isolated
power supply to this end.
For the evaluation of measured values during equivalent leakage current
measurement please refer to chapter 21.2.

10.3 High-Voltage Test (Feature F02 or SECULIFE ST HV)
Only safety class I and II devices can be tested, which can be connected
to the test socket.
The high-voltage test is performed with direct voltage. In order to comply
with requirements for alternating voltage, testing is performed with 1.5-
fold direct voltage. This multiplier is applied automatically during testing. A
selected nominal voltage of 3.5 kV thus results in a DC output voltage of
5.25 kV.
Output voltage is measured for the entire duration of the test, and its min-
imum value is determined. The minimum voltage value is indicated as the
test result. If this value is less than the pre-selected test voltage, the test is
failed.
The conversion factor must be taken into consideration for testing and
calibration of the SECULIFE ST
HV.
The device is designed such that special measures in accordance with
DIN VDE 0104 (high-voltage test) need not be observed.
This is accomplished by means of the following characteristics:
1. Continuous short-circuit current is less than 3 mA (DC).
2. Discharge energy (at 5.25 kV) is less than 350 mJ.
In order to comply with high-voltage test regulations despite the minimal
continuous short-circuit current, the charging capacitors are connected to
the test socket (L, N) with relatively low-value protective resistors. This
results in a peak short-circuit current value of approximately 5 A (at 5 kV),
which causes plainly audible and visible sparking.
Connection
High-voltage testing can only be performed via the test socket. The pro-
tective conductor at the socket is grounded during the high-voltage test.
Safety class I:
The test is conducted bet-
ween the short-circuited
mains poles L-N and the
protective conductor PE of
the test socket.
If safety class II is recog-
nized, the test is conducted
between the short-circuited
conductors L-N of the test
socket and the probe (con-
nection 4-5).
Caution: High-Voltage!
Touc h neither the test socket nor the device under test during
voltage testing!
A high-voltage of up to 5.5 kV is present at the test socket output!
A current may flow over your body, and although it does not
reach life endangering levels, the resulting shock is plainly
discernible.
Previous testing of the protective conductor is absolutely essential
for safety class I devices because if the protective conductor is in-
terrupted, the high-voltage test does not charge all dielectric ma-
terial and the scope of testing is thus insufficient.
Connection
õ Insert the mains plug from the device under test into the test socket.
õ Safety class II: Connect the probe to jacks 4 and 5.
Attention!
!
Make sure that the application parts (18) are not connected dur-
ing high-voltage testing!
Individual Test
õ Set the rotary selector switch to the Iso/HV position.
õ Select the U-HV menu with the key and acknowledge with the
key.
õ If the device under test has not yet been switched on, a message to
this effect appears at the display. Nominal voltage is then selected.

õ Safety class II: Contact all exposed, conductive parts, simultaneously
if possible, in order to avoid unnecessarily long test durations or
repeats. Avoid contacting individual parts sequentially.
õ After the key is released, the equivalent AC voltage is displayed which
occurred during testing. This voltage is indicated as the test result. If
this value is less than the pre-selected nominal voltage, the test is
failed.
õ If you want to repeat the test, press the key. The test sequence is
started over again with selection of nominal voltage.
Attention!
!
If sparkover should occur, the test is immediately interrupted
and the voltage measured at the moment sparkover occurred is
display as U
HV AC
.
If the device is disconnected from the test socket during testing,
even though this is prohibited, the test is immediately inter-
rupted. The following message is displayed: “Caution, device
under test is still charged!”
Testing as Part of a Test Sequence
õ Select the high-voltage menu under the setup function for the respec-
tive test regulation in order to set parameters for the high-voltage test.
õ Enter the desired AC nominal voltages for safety classes I and II. The
instrument multiplies the respective AC nominal voltage by a factor of
1.5, which represents the actual DC test voltage (see chapter 10.3).
Test voltage is determined based upon the selected, or the automati-
cally recognized safety class.
õ Save the setup values to memory.
õ Start the high-voltage test by pressing the key, if “manual
sequence” has been selected in the setup menu.
õ Safety class II only: Contact the device under test with the probe.
Activation of high-voltage is indicated with an acoustic signal.
The selected nominal voltage of 3.5 kV results in a DC output voltage of
maximum 5.25 kV.
The high-voltage test is ended auto-
matically after the test duration has
elapsed.

11 Leakage Current Measurement
Select the I
xx
measurement and start.
Each time line voltage is applied to the
test socket, L and N are reversed, if this
function has been selected in the leak-
age current menu (see chapter 11 on page 26).
Attention:
Leakage Current Measurement
During leakage current measurement it is imperative to ensure that the de-
vice under test is operated at line voltage. Exposed conductive parts may
be charged with hazardous contact voltage during the test and may con-
sequently not be touched under any circumstances. (There is a power
shutdown as soon as the leakage current is higher than approx. 10 mA).
Frequency response is
taken into consideration
in accordance with the
digram to the right when
leakage current is mea-
sured.
11.1 Earth Leakage Current I
PE
(Feature KA01)
Current which flows from the power pack over the insulation to the
protective conductor, and thus to earth.
Attention!
!
The protective conductor is disabled during this measurement.
11.2 Contact Current
Current which flows from housing
parts which are not connected to
the protective conductor via an
external conductive connection
to earth or another part of the
housing. Flow of current via the
protective conductor is excluded
in this case.
The AC component is mea-
sured. The DC component can
also be measured if individual
measurement is performed (in-
stead of a test sequence).
EN 60601/VDE 0751: The following sequence is programmed for measuring
and documenting several exposed conductive parts:
If the acoustic signal chain changes from long to short intervals, it means
that measurement is completed and the next measuring point can be se-
lected and scanned (key ).
If each measured value is to be recorded (printed), it can be done by
pressing the key after each measurement (on condition that „Direct
print-out“ is activated, see chapter 18).

11.3 Patient Leakage Current I
PL
Current which flows from an ap-
plication part via the patient to
earth. This current may be caused
by an unintentional interference
voltage at the patient, and may
flow via the patient and an insu-
lated, floating type F application
part to earth. Useful patient cur-
rent is excluded in both cases.
AC and DC components are measured.
Note
+
Patient leakage current must also be measured if application
parts are available.
The displayed test voltage must be documented.
11.4 Patient Auxiliary Current I
PA
(Feature KA01)
Current which flows within the
patient between the electrodes of
the application part. Use for in-
tended purpose is assumed. Fur-
thermore, the current should not
cause any physiological effects.
For example, this is the case for
input current from amplifiers, or
current used for impedance
plethysmography.
AC and DC components are measured.
11.5 Residual Current I
RC
Sum of instantaneous current values which flow via the L and N conduc-
tors at the device mains connection (also known as differential current).
Residual current is practically identical to fault current in the event of an er-
ror. Fault current: Current which is caused by an insulation defect, and
which flows via the defective point.
11.6 Device Leakage Current I
LC
per IEC 62353 (VDE 0751-1)
Device leakage current is the
sum of all leakage currents from
the housing, all accessible
conductive parts and all applica-
tion parts to PE. Measurement
must be performed for both
mains polarities and the largest
value is documented.
Note
+
The highest device leakage current value and line voltage must
be documented.
Attention!
!
The protective conductor is interrupted during this
measurement.

P: potential lead for 4-wire measurement
The potential lead must be connected to the outgoing protective
conductor at the distributor.
Cable resistance is measured from the device under test to the test instru-
ment without potential lead P. This value may deviate
significantly from actual protective conductor resistance, because the lead
is measured along with the test instrument installation. Resistance from
the probe terminal to contact P at the protective conductor is measured
with the potential lead.

14 Function Test
The device under test can be subjected
to a function test with line voltage via the
integrated test socket.
In addition to testing with the selector switch in the function test position,
a function test can also be performed immediately after safety testing has
been passed in accordance with the selected standard (not possible for
safety class III devices).
Attention!
!
The function test may only be performed after the DUT has
successfully passed the safety test.
Note
+
Each time line voltage is applied to the test socket, phase con-
ductor L and neutral conductor N are reversed, assuming that
“polarity reversal = X” is selected in the I leakage switch setting.
Note
+
The function test is only possible if the device under test has
been connected to the test socket (21).
Measurements
The function test includes the following measurements:
–Voltage U
LN
between the L and N conductors
Residual current ΔI
(corresponds to fault current between L and N)
Load current I
a
Active power P
Apparent power AP (calculated)
Power factor PF (cos ϕ calculated, display > 10 W)
Electrical energy W
On-time t for U
LN
at socket (21)
The following values are also displayed in all test sequences in switch po-
sition AUTO after the function test has been completed:
Maximum residual current ΔI
max
Maximum load current I
Lmax
Maximum active power P
max
Power factor is calculated from active power and apparent power.
Power factor corresponds to cos ϕ for sinusoidal quantities (line voltage
and load current).
Attention!
!
Starting the Function Test
For reasons of safety, the device under test must be switched
off before the function test is started. This precaution prevents
inadvertent start-up of a device under test which may represent
a hazard during operation, e.g. a circular saw or a disc grinder.
Ending the Function Test
After completion of the function test, devices under test must be
turned off with their own switch – especially devices with
relatively high inductivity.

Short-Circuit Test
1 Test for shorts between N and L.
2 Test to determine whether or not
the N or L conductors are short-
circuited to the protective
conductor.
Note
+
A short-circuit at the device under test is recognized
automatically by the test instrument. A message appears
at the display (9), and the function test is disabled.
If the lamp blinks (15), line voltage can be switched to the test socket
with the key (14), and the measurement can be started. If the lamp (15) is
lit continuously, line voltage is present at the test socket.
The test socket can be rendered voltage-free with the key (14), or the
function test can be ended with the key (12).

15 Measurements in Accordance with National and
International Standards with Selector Switch in Auto Position
If measurements need to be performed in accordance with given stan-
dards which require specific tests, and if results need to be stored and
documented with a test report, an automatic test sequence is advisable
instead of individual measurements.
Note
+
for tests per EN 60950, EN 61010 and EN 60335
The DUT must be connected to the test socket for the automatic
test sequence! The DUT must comply with safety class I or II.
õ Connect the test instrument to mains power.
A mains connection test is initialized (see chapter 3.2 on page 12).
õ
Connect the DUT to the test socket at the test instrument (see
chapter 7 on page 17). The test instrument initializes
connection type recognition
.
õ Set the selector switch to the Auto position. If the DUT has been con-
nected to the test socket, safety class recognition is performed. Other-
wise, the safety class must be specified manually. In the initial program
window, move the cursor up with the
key into the third line and ac-
knowledge with the key. A safety class can now be selected with
the
and keys and acknowledged with the key.
õ In order to select the regulation for which testing is to be performed,
move the cursor up within the initial program window with the
key
into the top line and acknowledge with the key. The desired stan-
dard can now be selected with the
and keys and acknowledged
with the key. If you always want to test in accordance with a spe-
cific standard, this can be stored as the default standard in the setup
menu. Otherwise, the selected standard only remains active until the
test instrument is disconnected from mains power (factory default set-
ting: VDE 0701-0702).
õ The test sequence can be configured in the Setup menu, limit values
can be changed if necessary and database options can be configured.
õ The test sequence is started by selecting Start test and by acknowledg-
ing with the key (see “Test Sequences”).
Tests which have already been included in chapters 9 through 14 are not
described here again. The only exception is measurement of extension
cables.
15.1 Test Sequences
Test sequences for the various standards are always run in the same
order, assuming that the device under test has been properly connected
and the mains connection test has been passed.
The test sequence can be run step by step with manual activation of each
subsequent step if this function has been specified, or automatically. Step
by step manual operation can be selected in the initial program window in
the setup menu under “Sequence” ... “manual sequence”.
Safety class: SC I or SC II is automatically recognized by the test instru-
ment. If the safety class is not correctly recognized, you can change it
manually. This manual correction is not stored however.
Visual inspection: If “visual inspection” has been activated
in the initial program window under “Sequence”.
If a part is recognized as defective by the user, it must be identified as
such by selecting it with the cursor and acknowledging with the key.
Protective conductor resistance measurement
(for SC I devices under test only)

•Perform function test if required:
The function test can be performed each time a safety test has been
successfully completed. The blinking signal lamp indicates that the
function test should be started. Beyond this, the function test can also
be started from the Function Test selector switch position. See chapter
14 on page 34 regarding performance of the function test.
•Display test results
(the worst measured values for the respective test sequence)
Save test results and print if required
15.2 Setting Up Test Sequences
The order of a test sequence cannot be changed!
However, it is possible to change limit values and measuring parameters,
and test steps can be added or skipped.
Principally, two test sequences are distinguished which are described on
the following page:
Sequence 1 (repair tests and periodic tests)
Sequence 2 (type tests)
Settings for the Test Sequence
Settings for the test sequence are not stored under a type designation,
but apply generally for the preset sequence of the respective test stan-
dard.
Type-related Settings (Type*)
(for tests per EN 60950, EN 61010 and EN 60335 only)
The type-related settings only include limit values. These limit values can
be stored for each type under an individual type designation. Measure-
ments the limit values of which have been deleted are skipped.
A type can be stored as default type. This type is indicated if the rotary
switch is set to Auto.
If no default type has been stored, the following appears for type in the
Auto rotary switch position: GENERAL and the general limit values of the se-
lected test standard apply.

Sequence 2 (type tests)
Type: ........ Sequences 1 and 2 differ primarily as regards the
type parameter. The user can set up any desired type
of device under test with sequence 2, for which the
same limit values and measuring parameters always
apply. Up to 125 different types can be defined. DUT
types are predefined for sequence 1 (EN 60601).
Designations made up of alphanumeric characters
(max. 10 characters) can be entered at the keypad of
a (P)SI module, or at a PC with a terminal program.
The test sequence, including all limit values, is saved
together with the selected type. We recommend
using the characters which identify the respective
standard as the initial characters in the designation. If
a type is queried from the initial program window
which does not belong to the currently selected stan-
dard, these characters identify the test sequence as
belonging to another standard.
Limit Values See chapter 4.6 on page 14.
Sequence See page 39.
Store as
Default All of the settings in the setup menu, i.e. the configu-
ration of the measuring parameters and the current
limit values can be saved with this command.
These values remain active even after setting the
selector switch to a different position, and after dis-
connection from mains power.
Delete The type which has been selected in the initial pro-
gram window can be deleted.

15.5 Testing Devices in Accordance with DIN VDE 0701, part 240
You can either change over to testing in accordance with the new
VDE 0701-0702 standard or perform the following measurements in ac-
cordance with the above-mentioned standard:
Testing safety class I and II data processing equipment and office machines as
individual devices and in combination with one another.
The following measurements can be performed in accordance with the
above mentioned standard:
Protective conductor R
PE
(permanent connection or with plug)
Test current: DC ±200 mA
Contact current I
According to DIN VDE 0701, part 240, the device protective conduc-
tor must be tested after maintenance, repair or modification of data
processing equipment and office machines, and exposed, conductive
parts must be tested for the absence of voltage. This applies to:
Safety class I devices for all exposed, conductive parts which are accessi-
ble to the user, and which are not connected to the protective conductor
Safety class II devices (totally insulated devices) for all exposed,
conductive parts which are accessible to the user
with the mains plug poled in both directions.
Setting Up the Test Sequence
See chapter 15.4 regarding the test sequence.
Special Parameters
Combined Testing
Safety class I and II devices can be tested individually or in
combination. All protective conductor connections are tested
first for interconnected safety class I devices, and then – as is
also the case for interconnected safety class II devices – all
exposed, conductive parts.
Connecting the Device Under Test
õ Connect the test instrument and the DUT as described below:
Connect both devices to separate mains outlets.
The outlets to which the test instrument and the safety class I DUT
are connected must share a common protective conductor!
Or connect the test instrument to the mains and the DUT to the test
socket at the test instrument.
Data Processing / Office Machines
Permanently connected or with plug
To test socket at the instrument
The requirement for testing with the mains
plug poled in both directions can be fulfilled
by connecting the DUT to the test
socket at the instrument, and by activat-
ing mains polarity reversal in the setup
menu under “Sequence”. Each time the
key (14) is activated, phase conductor L
and neutral conductor N are reversed at
the test socket.
Attention!
!
Testing with mains polarity reversal or with the mains plug poled
in both directions results in interruption of supply power to the
affected data processing equipment or office machine. This test
may thus only be conducted with the consent of the operator of
the data processing equipment or office machine.
If the DUT is defective, the electrical system’s RCCB may be
tripped during testing which would also result in interruption of
supply power to the affected equipment or office machine.
The manufacturer of the test instrument assumes no liability for
the loss of data or other damage which result from use of the
test instrument.

Extension Cables up to 5 m Long
Protective conductor resistance between the earthing contact at the
mains plug and all exposed metal parts may not exceed 0.3 Ω for safety
class I devices. This value may not exceed 1 Ω for permanently con-
nected data processing systems (DIN VDE 0701, part 240).
Extension and Connector Cables Longer than 5 m
An additional cable resistance of 0.1 Ω, however, not more than 1 Ω, is al-
lowable as of a length of 5 m for each additional 7.5 m.
Resistance testing for cables longer than 5 m is thus advisable (see also
limit values on page 20.

be tested. Jacks A through K (for connection of cables or probes) can
also be assigned to groups (application parts) for mutual testing.
Selecting Preset Test Combinations
õ Use the cursor to select test combinations with groups of 1, 2, 5 or 10
application parts and acknowledge with the key.
The groups are assigned automatically after the application parts have
been selected.
Selecting User Defined Test Combinations
õ Select the respective application part from the JACK column with
the cursor and acknowledge with the key. You can set up a user
defined group for each application part which includes 1 to 10
application parts with the cursor keys in the GR column (GRoup).
Acknowledge your settings with the key.
As long as at least one group number has been entered, the application
parts test is preset in the “To Socket” window.
The application part type with the strictest limit value takes precedence
in the initial window. All groups are set to this type. Various types can be
assigned to the groups with “direct print” (adjustable option in the setup
menu).
If testing is not to be performed with application parts, the group assign-
ment must be cancelled with the “clear” function.
The TYPE is filled in automatically if the safety class has already been
entered to the “To Socket” window.

16 Storing in (P)SI Module (Accessory) and Database Operations
(Feature KB01)
16.1 Storing Measurement Data in the (P)SI Module
Upon completion of a measurement – message „Test passed/failed“ is
displayed – you can file the measurement data in the memory of the (P)SI
module.
õ Press the STORE key at the (P)SI module.
A text entry field is displayed.
õ You may now enter your comments on the measurement
and/or an ident. no.
õ Press the STORE key once more in order to save the measurement data
and your comments.
The message: „Data are being stored“ is shown on the display.
A detailed description is included in the operating instructions for your
(P)SI module in the chapter „Display, print and store protocol“.
16.2 Database Operations
16.2.1 Storing Test Results to the Test Instrument
If no (P)SI module has been connected, up to 125 reports can be stored
to the test instrument (without function test values and without comments
on DUT). The reports can be viewed as required at the instrument and can
be printed out, for example with the help of a terminal program, see chap-
ter 18.
The reports are sorted by time and date and are displayed with the ID
number. If no ID number was assigned, date and time are automatically
saved instead.
As an alternative, consecutive numbering can be selected.
16.2.2 Uploading Report Templates into Test Instrument, Reading Out From the
Test Instrument, Editing at the PC and Re-Saving to the Test Instrument
The „Test result“ menu allows for storage of up to 4 report templates in the
test instrument. Report templates are uploaded from a file at a PC to the
test instrument (“Load file”). Templates can also be uploaded from the test
instrument to a PC (“Templates from Secutest”), and then edited and re-
saved.
After completion of a test (“Passed” or “Failed” appears at the instru-
ment’s LCD), the test results are read out to one of these report templates
in the form of report data (depending upon the selector switch position or
test regulation) via the RS 232 interface. The report menu in the test in-
strument is activated with the and keys to this end. In order to read
out the report data at a PC, it is necessary to connect the SECUSTORE stor-
age adapter with the RS232 interface. The report can, for example, be
displayed with the PC analysis program WinProfi (as from version 3.06) or
ETC (as from version 1.22).
16.2.3Reading Out and Saving Test Results / Test Data from the (P)SI Module
Test results saved to the test instrument can be displayed, edited, printed
(only PSI module) or saved after reading them into a PC using the desired
report template.
Data can be processed immediately after completion of the test, or from
the database (Feature KB01). Data can be saved with or without a report
template (e.g. for further processing with PS3).
Test results saved to the (P)SI module can also be read out, printed (only
PSI module), saved or processed by means of a report template.
Easy method of printing out reports:
Activate the „test result“ menu in the update and options installation pro-
gram. When the test result is displayed in the test instrument select the
print function (press key „Cursor up“, then set the cursor on „print“ and
press ENTER).
17 Recognition of Probe to Protective Conductor
(Feature KD01)
The protective conductor measurement is expanded to include the
function: “automatic recognition of measuring point change”.
During protective conductor measurement, the instrument recognizes
whether or not the probe is in contact with the protective conductor, and
indicates these two possible conditions by means of acoustic signals.
This function is helpful if several protective conductor connections need to
be tested. The function can be activated in the “test sequence setup”
menu with “auto measuring point” (see “changes to the switch position
menu” above).
GMC-I Messtechnik GmbH 59
18 Storing Test Results and Printing in Report Form
You can shift to the Protocol menu from
any of the displayed test results (1
st
page) with the help of the key.
Storing to the Test Instrument
Measurement results for the current
test can be stored to the test instru-
ment, the results of the current test can
be printed out to the corresponding re-
port form, previously stored test results
can be queried (scroll: Feature KB01,
see chapter 16) and all stored mea-
surement results can be read out from
this menu.
The report template automatically
complies with the standard of the se-
lected switch position, provided that
parameter „Select template“ has been
deactivated.
If parameter „Select template“ is activated, it is possible to select one of 5
different report templates. Templates 1 to 4 can be modified via the up-
date and options installation program SECU-Up, see chapter 16.2.2.
Storing to the SECUSTORE Storage Adapter (Accessory)
Connect the SECUSTORE storage adapter with the test instrument via the
RS232 interface. The (P)SI module may not be connected.
Direct Print-Out (Feature KE01 in Combination with a PSI Module or SECUSTORE
Storage Adapter)
After completion of each test (individual test or at the end of a test
sequence), test results are read out directly via the RS232 interface.
When the PSI module is connected (accessory, not part of the standard
equipment), the result is directly printed on paper. When the SECUSTORE
storage adapter is connected, the test result is stored to the SECUSTORE
memory.
In this operating mode, no results can be saved to the internal memory or
to the (P)SI module.

21 Appendix
21.1 Evaluation of Measured Values for Individual Measurements
as well as for Calculated Quantities
In order to assure that the limit values for the individual measurements
are always observed, device measuring error must be taken into
consideration.
The table in the appendix allows for calculation of the required minimum
display value for each respective measurement which must appear at the
instrument in consideration of measuring error (under nominal conditions
of use), in order to assure that the required limit value is not fallen short of
(DIN VDE 0413, part 1). Intermediate values can be interpolated.
Measuring Error for Test Sequences
The test instrument takes respective measuring error into consideration
during automatic test sequences, and corrected results are entered into
the test report, as long as this function has been activated in the setup
menu under “include service error.
Omitting the Protective Conductor Test in the Case of Fully Insulated Devices
You are testing a fully insulated safety class I device (e. g. screen, sub-
mersible pump, etc.), which is not equipped with an external protective
conductor contact.
The decision as to the necessity of a protective conductor test in this case is
to be taken by a qualified electrician who should also assume responsibility.
You can omit the protective conductor test by pressing the key as soon
as the following instruction is shown: „Please connect the probe with the
protective conductor of the DUT“.
Tables for the calculation of minimum display values for insulation
resistance and maximum display values for protective conductor resis-
tance, equivalent leakage current, probe current and residual current in
consideration of device measuring error:

Depending upon resolution
21.2 Evaluation of Measured Values during Equivalent Leakage Current
Measurement (Automatic Test Sequence According to Standard)
During equivalent leakage current measurement, L and N are intercon-
nected whereupon a test voltage of 230 V is applied between LN and PE
and the leakage current is measured. Thus the most adverse case (N in-
terrupted) is being tested.
As a rule, this results in at least double the value of the direct leakage cur-
rent measurement (since all discharge capacitors are placed in parallel).
If frequency converters are used in addition to that, it is no longer possible
to compare the measured values between direct leakage current and
equivalent leakage current method. In this case, we recommend conduct-
ing individual measurements in accordance with the residual current
method.

22 Maintenance - Recalibration
22.1 Housing Maintenance
No special maintenance is required for the housing. Keep outside
surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the
use of cleansers, abrasives or solvents.
22.2 Recalibration
The respective measuring task and the stress to which your measuring in-
strument is subjected affect the ageing of the components and may result
in deviations from the guaranteed accuracy.
If high measuring accuracy is required and the instrument is frequently
used in field applications, combined with transport stress and great tem-
perature fluctuations, we recommend a relatively short calibration interval
of 1 year. If your measuring instrument is mainly used in the laboratory and
indoors without being exposed to any major climatic or mechanical stress,
a calibration interval of 2-3 years is usually sufficient.
During recalibration* in an accredited calibration laboratory
(DIN EN ISO/IEC 17025) the deviations of your instrument in relation to
traceable standards are measured and documented. The deviations de-
termined in the process are used for correction of the readings during
subsequent application.
We are pleased to perform DAkkS or factory calibrations for you in our cal-
ibration laboratory. Please visit our website at www.gossenmetrawatt.com
( Company DAkkS Calibration Center or FAQs Calibration
questions and answers).
By having your measuring instrument calibrated regularly, you fulfill the re-
quirements of a quality management system per DIN EN ISO 9001.
Standards DIN VDE 0701-0702 and IEC 63353 (VDE 0751) stipulate that
only measuring instruments which are regularly tested and calibrated may
be used for testing.
* Verification of specifications or adjustment services are not part of the calibration.
For products from our factory, however, any necessary adjustment is frequently
performed and the observance of the relevant specification is confirmed.
22.3 Safety Checks
Check the safety of your test instrument on a regular basis. We recom-
mend the same test intervals as for recalibration.
The SECUTEST... is designed as a totally insulated instrument in accor-
dance with standards IEC 61010 and VDE 0404. The protective conduc-
tor is only used for measurement purposes and is therefore not accessible
in idle state. A protective conductor test at the test socket can be per-
formed as follows:
Ð Connect the SECUTEST... to a multiple distribution box.
Ð Conduct a contact current measurement for permanently installed
DUTs (the test socket may not be connected to any load).
Ð Measure the protective conductor resistance between the neighbour-
ing socket of the multiple distribution box and the test socket.
Ð The measured value may not exceed 0.3 Ω.
Insulation resistance between LN and PE in the SECUTEST... equals ap-
prox. 150 kΩ for metrological reasons.
This must be taken into account when performing the safety checks, i.e.
the protective conductor current measurement must produce a value
below 3.5 mA, instead of insulation resistance measurement (if the equiv-
alent leakage current measurement method has been chosen, the value
must remain below 7 mA).
Apart from this, the SECUTEST... features 3 exposed conductive parts for
which contact current measurement must produce a value below 0.5 mA:
RS232 interface
metallized start key
protective conductor clip at the test socket.
