Eger fonksiyona pîvandina herikê dev ji xebatê berde, dibe ku pêdivî bi guhertina fîşekê hebe.

1. Piştrast bike ku multimeter vemirî ye û hemî rêberên ceribandinê qutkirî ne.
2. Remove the battery compartment cover and batteries.
3. Locate the fuse(s) inside the compartment. The MM20HV typically uses a 200mA/250V fast-blow fuse for the mA range and a 10A/250V fast-blow fuse for the 10A range.
4. Carefully remove the old fuse and replace it with a new fuse of the exact same type and rating.
5. Replace the batteries and battery compartment cover.

Giring: Never use a fuse with a different rating or bypass a fuse. This can damage the multimeter and pose a serious safety hazard.
