Fuse Replacement
The current input terminals of your multimeter are fuse protected. The fuses are
located next to the battery compartment.
–The
terminal is protected by a 10 x 35 mm 440 mA/1000 V 30 kA
fast-acting fuse (Fuse 1).
–The terminal is protected by a 10 x 38 mm 11 A/1000 V 30 kA fast-acting
fuse (Fuse 2).
If you are certain that the fuse is faulty, replace it with one of the same size and
rating.
No recalibration is required after replacing the fuse.
Before you proceed with the fuse replacement, remove all cable connections
to the terminals and ensure that the rotary switch is at the OFF position.
