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 possi-
ble, you have to change the fuse.
The measuring device enables testing fuses when the hou-
sing 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".
- You can then replace the broken fuse with a new one of the same type and nominal voltage or one of
the same build. The fuses have the following values:
Fuse
Nominal data
Switching capability
Dimensions
- Now close the housing carefully again.
Using mended fuses or bridging the fuse holder is not permitted for safety reasons.
It may cause fires or arc explosions. Never operate the meter when it is open.
