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:
Fuse
Nominal data
Breaking capacity
Dimension (ø x L)
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.
