Care and Maintenance
WARNINGS:
• Do not let any water drip inside
the meter while cleaning it.
• Make sure that the meter is com-
pletely dry before using it.
REPLACING THE FUSES
If the meter does not work, you might
need to replace one or both of the
fuses with the spare fuses we have
included with your meter. The spare
fuses are inserted in a plastic holder
inside the meter’s cabinet near the
RS-232 connector on top of the
meter.
The meter contains a 500mA, 250V
ceramic fuse (Littelfuse 314.500) and
a 12A, 250V ceramic fuse (Littelfuse
314012).
Caution: Do not use a fuse brand or
rating other than those specified here.
Doing so might damage your meter.
You can order the fuses through your
local RadioShack store.
1. If the meter is on, rotate the func-
tion selector to
OFF
to turn it off.
Then disconnect the test leads if
they are connected.
WARNING: To avoid electric
shock, you must disconnect the
test leads before you remove the
battery cover and back cover.
2. Use a Phillips screwdriver to
loosen the battery cover’s screw,
then lift off the battery cover.
3. Remove the battery.
4. Use a Phillips screwdriver to
loosen the screws from the back
cover and gently pull apart the
case.
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. Then remove
the spare fuse from the plastic
holder and insert it into the fuse
holder through the loop of the
attached ribbon.
7. Replace the back cover and
secure it with the screws.
8. Reinstall the battery (see “Install-
ing a Battery” on Page 13), then
replace the battery cover and
secure it with the screw.
WARNING: Do not operate your
meter until the back cover is in place
and secured.
