Use a clean, lint-free, antistatic and slightly damp cloth to clean the device and display. Allow the
device to dry completely before using it for the next measuring task.
c) Opening the measuring device
For reasons of safety, it is only possible to replace the fuse and battery when all test leads have been
removed from the measuring device. The battery and fuse compartment cannot be opened when test
leads are plugged in.
In addition, when the housing is opened all measuring sockets are mechanically locked in order to
prevent the later insertion of the test leads. The locking will be automatically removed when the battery
and fuse compartment is again closed.
The housing is designed so that when the battery and fuse compartment is open only the battery
and fuses can be accessed. The housing does not have to be opened completely or taken apart any
longer. These measures increase the user safety and user-friendliness.
Proceed as follows to open:
1. Remove all test leads from the measuring device and switch
it off.
2. Loosen and remove the battery compartment screw (15) on
the back.
3. Fold out the positioning bracket (13). Pull the battery and
fuse compartment lid downwards from the measuring device
(Fig. 11).
4. The fuses and battery compartment are now accessible.
5. Close the housing in the reverse order and screw closed the
battery and fuse compartment.
6. The measuring device is again ready for use.

d) Fuse check/fuse replacement
The current measuring ranges are protected with high breaking capacity fuses. If no measurement is
possible in this range, the fuse must be replaced.
The measuring device allows the testing of fuses with the housing closed.
Proceed as follows to test:
1. On the rotary switch, select the measuring range "Ω".
2. Insert a test lead in the °CHzVΩ socket (7).
3. Contact the current measuring socket to be tested with the
test prod (Fig. 12).
4. If a measured value is displayed, the fuse is okay. However,
if the display reads "OL", the corresponding fuse is defective
and must be replaced.
Proceed as follows to replace the fuse:
1. Remove the attached test leads from the measuring circuit and from your measuring device. Turn
off the DMM.
2. Open the housing as described in Section "c) Opening the measuring device" (page 76).
3. Replace the defective fuse with a new one of the same type and current rating or similar. The fuses
have the following values:

Item no.
4. Close the housing again carefully.
For reasons of safety, the use of repaired fuses or the bridging of the fuse holder
is not permitted. This can lead to fire or electric arc explosion. Do not use the
measuring device in this state under any circumstances.
