d) 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 de-
vice. 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:

Dimensions
• Now close the housing 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.
