MD 9060 Digital Multimeter Series Safety

1 Safety

Terms in this manual

WARNING identifies conditions and actions that could result in serious injury or even

death to the user.

CAUTION identifies conditions and actions that could cause damage or malfunction

in the instrument.

This manual contains information and warnings that must be followed for operating the

instrument safely and maintaining the instrument in a safe operating condition. If the

instrument is used in a manner not specified by the manufacturer, the protection

provided by the instrument may be impaired. The meter is intended only for indoor use.

The meter protection rating, against the users, is double insulation per IEC61010-1 2nd

Ed., EN61010-1 2nd Ed., UL61010-1 2nd Ed. and CAN/CSA C22.2 No. 61010.1-0.92 to

Category IV 1000 Volts AC & DC.

MD 9060 Terminals (to COM) measurement category:

V / mAA / A : Category IV 1000 Volts AC & DC

Per IEC61010-1 2nd Ed. (2001) Measurement Category

Measurement Category IV (CAT IV) is for measurements performed at the source of

the low-voltage installation. Examples are electricity meters and measurements on

primary overcurrent protection devices and ripple control units.

Measurement Category III (CAT III) is for measurements performed in the building

installation. Examples are measurements on distribution boards, circuit- breakers, wiring,

including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed

installation, and equipment for industrial use and some other equipment, for example,

stationary motors with permanent connection to the fixed installation.

Measurement Category II (CAT II) is for measurements performed on circuits directly

connected to the low voltage installation. Examples are measurements on household

appliances, portable tools and similar equipment.

WARNING

To reduce the risk of fire or electric shock, do not expose this product to rain or

moisture. To avoid electrical shock hazard, observe the proper safety precautions when

working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a

potential shock hazard to the user. Do not touch test lead tips or the circuit being tested

while power is applied to the circuit being measured. Keep your fingers behind the

finger guards of the test leads during measurement. Inspect test leads, connectors, and

probes for damaged insulation or exposed metal before using the instrument. If any

defects are found, replace them immediately. Do not measure any current that exceeds

the current rating of the protection fuse. Do not attempt a current measurement to any

circuit where the open circuit voltage is above the protection fuse voltage rating.

Suspected open circuit voltage should be checked with voltage functions. Never attempt

a voltage measurement with the test lead inserted into the A/mA or A input jack. Only

replace the blown fuse with the proper rating as specified in this manual.
