e) Replacing the 10 A input fuse
The 10 A current measuring input is equipped with a ceramic high-performance fuse. If you cannot take measure-
ments in this range, you will need to replace the fuse.
Follow the steps below to replace the fuse:
- Disconnect the connected test leads from the measuring circuit and from your DMM. Switch the DMM off.
- Remove the battery/fuse compartment cover (see "Opening the battery/fuse compartment").
- Replace the defective fuse with a new fuse of the same type and nominal voltage. The F1 fuse has the following
values:
Ceramic high-performance fuse FF 12 A/1000 V
Dimensions: 32 mm x 6.4 mm
- Carefully replace the battery/fuse compartment cover.
Using patched fuses or bridging the fuse holder is not permitted for safety reasons. This may cause
a fire or explosion. Never use the multimeter when the battery/fuse compartment is open.
The mA/µA measurement input is equipped with a maintenance-free, self-resetting PTC fuse. It is
not necessary to replace the fuse in this measurement input.
