14.4 Replacing the 10 A input fuse
The 10 A current measuring input is equipped with a ceramic high-performance fuse.
If you cannot take measurements in this range, you will need to replace the fuse.
Follow the steps below to replace the fuse:
1. Disconnect the measuring leads from the circuit and the multimeter, and then
switch off the multimeter.
2. Remove the battery/fuse compartment cover (see “Opening the battery/fuse
compartment”).
3. Replace the defective fuse with a new fuse of the same type and nominal volt-
age.

F1 fuse: Φ6.35×32 mm, FF 10 A, H 600 V, breaking capacity: 10 kA
4. 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 input is equipped with a maintenance-free resettable PTC
fuse. You do not need to replace the fuse in this input.
When the meter is being used for mA/µA measurement, but the meter is
mistakenly connected to a high-energy high-voltage power supply, then
the ceramic tube fuse will work and probably blow to protect the meter. In
such case, the blown ceramic tube fuse is required to be replaced by a
new one.
