When inserting the batteries, begin with the positive
pole of the battery and fit the negative pole into place
afterwards, in order to avoid damage to the contacts of
the positive pole.
➭ Tighten the battery cover with the screw.
17.2 Fuses
The 10 A fuse protects the 10 A range, the 1.6 A fuse protects
the 66 mA, 660 mA current measuring ranges. When a fuse
blows, eliminate the cause of the overload before using the
multimeter again!
Replacing the Fuses
• Place the multimeter on its face, loosen the two bottom
cover screws on the rear and remove the bottom cover by
lifting it from the bottom.
• Remove the defective fuse from the fuse holders.
• Remove the blown fuse, e. g. with the aid of a probe, and
replace it with a new one.
• Tighten the bottom cover with the two screws.
Fuse types for current measuring ranges up to 660 mA:
– FF (UR) 1.6 A / 1000 V AC/DC; (10 kA); 6.3 mm x 32 mm
For 10 A current measuring range:
– FF (UR) 10 A / 1000 V AC/DC; (30 kA); 10 mm x 38 mm
Caution
It is imperative to ensure that only the fuses specified above
are installed!
If a fuse of other cut-out capacity, other nominal current or
other switching capacity is used, a dangerous situation exists,
and there is a risk of damaging protective diodes, resistors or
