Replacing the Fuse

The current measuring ranges are protected by high-performance fuses. If measuring in this range is no
longer possible, you have to change the fuse.
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 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:
