OPERATING & MAINTENANCE TIPS
When the icon appears in the upper left corner of the LCD, immediately
replace the meter's "9V" battery by following the instructions on page 7.
To replace a blown fuse:
1. Power off the meter.
2. Unplug the test leads.
3. Turn the meter over and loosen the small Phillips-head screw in the middle
of the back that secures the meter's battery compartment cover. Remove the
cover, taking care not to lose the screw.
4. Remove the meter's gray rubber holster by carefully pulling its front lip over
the housing, starting at the top and working your way around the perimeter
to the bottom.
5. Remove the four larger Phillips-head screws that secure the two halves of
the housing and pull the two halves apart.
6. Locate the blown fuse on the circuit board (see photo at
right). The DMM uses two different white cylindrical
fuses. The TEMP

fuse. The A jack is protected by an F10A/600V fuse.
Each fuse is located directly behind the jack it protects.
7. Using another multimeter or a continuity checker, verify
that the suspected blown fuse produces a resistance
reading consistent with an open circuit.
8. Replace the blown fuse by a fuse with the same current
and voltage ratings.
9. Rejoin both halves of the housing by replacing and
tightening its four screws.
10. Replace the battery compartment cover and tighten its screw.
11. Replace the gray rubber holster.
After subjecting the meter to a large change in ambient temperature, wait at
least 30 minutes before making measurements to guarantee the accuracy of
readings.
Remove the battery when storing the meter or when you do not expect to use it
for an extended period of time (months rather than weeks).
Do not disassemble the meter or immerse it in water.
