Cleaning
To clean the meter, use a soft cloth moistened with water. Using benzene, alcohol,
acetone, ether, paint thinner, lacquer thinner, ketone or other solvents may deform
or discolor the meter and its display.
Troubleshooting
If the meter appears to operate improperly, check the following items first.
1. Review the operating instructions to ensure the meter is being used properly.
2. Inspect and test the continuity of the test leads.
3. Make sure the battery is in good condition. The low battery symbol B appears
when the battery falls below the level where accuracy is guaranteed. Replace a
low-battery immediately.
4. Check the condition of the fuses if the current ranges operate incorrectly.
XWWARNING
To avoid electrical shock remove the test leads from both the
meter and the test circuit before accessing the battery or the
fuses.

To access these parts, you must first remove the cover from the battery
compartment. The battery cover is on the rear of the meter and is held in place with
two screws. After removing these screws, you can easily remove and replace the
battery. To replace the mA fuse, pry it from its clips using a small screwdriver. A
spare mA fuse is located between the battery and the mA fuse.
