17.2 Fuses
The 16 A fuse protects the 10 A range, the 1.6 A protects 66mA ,660mA
current measuring ranges. When a fuse blows, first eliminate the cause
of the overload before using the multimeter again !
Replacing the Fuses
n
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.
n
Remove the faulty fuse from the fuse holders.
n
Tighten the bottom cover with the two screws.
n
Remove the blown fuse, e.g. with the aid of a probe, and replace it
with a new one.
Types fuses for current measuring ranges up to 660 mA:
For current measuring ranges up to 660 mA:
--FF (UR) 1.6 A / 1000 V AC/DC ; (10
k
A) ; 6.3 mm x 32 mm
For 10A current measuring range:
--FF (UR) 16 A / 1000 V AC/DC ; (30
k
A) ; 10 mm x 38 mm
Caution
Absolutely verify that only the specified fuse is 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 danger of damaging
protective diodes, resistors or other components. The shorting of the
fuse holder is not permissible.
17.3 Case
Special maintenance of the case is not required .Take care that the
surface between the connection sockets is clean. For cleaning take a
moist cloth. Avoid scrabbing.
