Maintenance

Battery replacement

1. Disconnect the meter from any test device or circuit before
opening the tester.
2. Loosen the recessed Phillips head screw at the bottom of the
tester. Do not remove the screw.
3. Hold the meter and pull the lower portion of the meter off until
the batteries are exposed.
4. Replace the two 'AAA' batteries observing polarity and dispose
of the old batteries properly.
5. Slide the meter back together and replace the screw.

Cleaning and Storage

Before cleaning the tester, ensure that the test leads are not connected to any circuit or
device. Wipe the meter only with a damp cloth as needed. Do not apply abrasives, solvents,
or other cleaners to the surface of the meter. Store with the battery removed and avoid
extreme temperature and humidity.
