d.) Checking the Fuse/Replacing the Fuse

The current measuring ranges are protected by high-performance fuses. If measuring in this range is no longer pos-
sible, you have to change the fuse.
The meter enables testing fuses when the housing is closed.
Proceed as follows for testing:
- Select the measuring range "Ω " on the rotary control.
- 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. If the
display continues to show "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 off
the DMM.
- Open the casing as described in chapter "Opening the
Meter".
- Replace the defective fuse with a new one of the same
type and rated current or one of the same build.The fus-
es have the following values:
Fuse
Nominal data
Switching capability
Dimensions
- Close the casing again carefully.
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.
