Cleaning
To clean the meter, use a soft cloth moistened with water. To avoid damage to the
plastic components do not use benzene, alcohol, acetone, ether, paint thinner,
lacquer thinner, ketone or other solvents to clean the meter.
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.
