 For measurements up to 600mA: connect the red test lead to the "µAmA" jack

and the black lead to the "COM" jack.

 For measurements up to 10A: connect the red test lead to the "10A" jack and

the black lead to the "COM" jack.

 Set the rotary switch to the µA range for measurements up to 600µA (only when

test probe is connected to the µAmA jack).

 Set the rotary switch to the mA range for measurements up to 600mA (only when

test probe is connected to the µAmA jack).

 Set the rotary switch to the A range for measurements up to 10A (only when test

probe is connected to the 10A jack).

 Press the SELECT button to select DC current (DCA) or AC current (ACA) mode.

 Connect the test probes in series with the circuit.

 Read the measured value from the display.

Notes:

o for DC-current measurements, when a negative polarity is present at the red

test lead, the indicated value is preceded by a “-” sign.

o The µAmA-range is protected against over current with a F630mA 1000V fuse,

the 10A-range is protected against over current with a F10A 1000V fuse.

8. Maintenance

Do not replace internal parts yourself. Replace damaged or lost accessories

by identical ones with the same specifications. Order spare accessories e.g.

test probes at your dealer.

a. General maintenance

Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or

solvents.

b. Fuse Replacement

Switch off the multi-meter, disconnect the test leads from the test points

and remove the test leads from the measuring jacks before replacing the

batteries or fuses.

Refer to the illustration on pages 3 of this manual.

 Remove the 4 screws at the back (indicated with in the illustration) and gently

open the meter.

 Remove the screw that holds the PCB in place (indicated with in the

illustration) and gently lift the PCB.

 Remove the fuse from the fuse holder and replace it with a new fuse of the same

type and with the same specifications (F630mA/1000V - Ø10.3x38mm,

F10A/1000V - Ø10.3x38mm).

 Close the meter meticoulsly.

c. Battery Replacement

To avoid false readings, which could lead to possible electric

shocks or personal injury, replace the battery as soon as the

battery indicator appears.

Switch off the multi-meter, disconnect the test leads from the test

points and remove the test leads from the measuring jacks before

replacing the batteries or fuses.

Refer to the illustration on pages 3 of this manual.

 Remove the 2 screws at the back of the meter (indicated with in the

illustration) and gently open the battery compartment.

 Replace the battery (9V 6LF22). Do not use rechargeable batteries. Insert

following the right polarity.

 Close the battery compartment and reseat the screws.
