Checking the Fuse/Replacing the Fuse
The current measuring ranges are protected by high-perfor-
mance fuses. If measuring in this range is no longer possible,
you have to change the fuse.
The measuring device enables testing fuses when the housing
is closed.
Proceed as follows for testing:
- Select the measuring range “Ω” on the rotary switch.
- Insert the measuring lines into the “VΩ” socket.
- Touch the test prod to the current measuring jack to the
tested.
- If a measured value is displayed, the fuse is OK. When the
display only shows “OL”, the respective fuse is defective
and needs to be replaced.
Proceed as follows for fuse replacement:
- Separate the connected measuring lines from the measuring circuit and the measuring device. Switch
the DMM off.
- Open the housing as described in chapter “Opening the Measuring Device”.
- Replace the defective fuse with a new fuse of the same type and nominal voltage. The fuses have the
following values:
