Error
Possible cause
The multimeter is not working.
Is the power indicator on?
Are batteries used up?
Check the state of the 9 V battery and the fuse.
Resistance measurement not possible.
Are batteries used up? Check the state of both micro (AAA) batteries
and the fuse.
No measurement using the V/mA
socket (7) is possible.
Is the fuse defective?
Check the fuse F 0.5 A/500 V (replacing the fuse).
No measurement using the 10 A
socket (4) is possible.
Is the fuse defective?
Check the fuse F 10 A/500 V (replacing the fuse).
There is no change of the measured
value.
Are the correct measuring sockets selected?
Is the correct measuring function selected (AC/DC)?
The multimeter is showing incorrect
readings.
Was the display zeroed (zero adjustment/zero ohm adjustment for
resistance measurement) before measuring?
Is the "Vrms/Vp-p" button (9) pressed?
Repairs other than the ones previously described should be carried out by an authorized
professional. If you have any questions concerning the operation of the multimeter, please do not
hesitate to contact our technical support.
