Possible cause
Solution
The multimeter does not work.
Is the battery empty?
Check the battery level and replace
the battery if necessary.
The measured value does not
change.
Have you selected the wrong meas-
urement mode (AC/DC)?
Check the display (AC/DC) and
select another mode if necessary.
Did you use the wrong terminals?
Check that the test leads are con-
nected to the correct terminals.
Is the hold function enabled?
Disable the hold function.
The multimeter cannot take
measurements in the 10 A range.
Is the fuse in the 10 A input defec-
tive?
Check the 10A F1 fuse.
The multimeter cannot take
measurements in the mA/µA
range.
The PTC fuse was triggered, which
limits the measuring current.
Reduce the measuring current or
switch to the 10 A measuring range.
Any repair work other than that described above must be carried out by an authorized technician.
