REPLACING THE FUSE
If the multimeter does not work, you
might need to replace the fuse with
the supplied 315 mA, 250V ceramic
fuse. The spare fuse is next to the
battery compartment.
Caution:
Do not use a fuse with rat-
ings other than those specified here.
Doing so might damage your multim-
eter.
Follow these steps to replace the
fuse.
1. Set the function selector to
OFF
,
then disconnect the test leads if
they are connected.
WARNING:
TO AVOID ELEC-
TRIC SHOCK, YOU MUST DIS-
CONNECT THE TEST LEADS
BEFORE YOU REMOVE THE
BACK COVER.
2. Use a Phillips screwdriver to
remove the screw on the upper
back of the multimeter. Then
remove the top cover.
3. Use a Phillips screwdriver to
remove the screw on the lower
back of the multimeter, then
remove the multimeter’s back
cover.
4. Remove the battery.
5. To remove the fuse, gently pull
the red ribbon holding it. The
fuse pops out.
6. If the fuse is blown, discard it and
save the ribbon (to use with the
next spare fuse you store in the
compartment). Then remove the
spare fuse and the ribbon hold-
ing it from the upper back of the
multimeter and insert it into the
fuse holder.
7. Replace the battery in the com-
partment.
Warning:
Do not operate your
multimeter until the back cover
and top cover are in place and
secured.
8. Replace the back cover and the
top cover, then secure them with
the screws.
