Product Maintenance

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.

To avoid electrical shock remove the test leads from both the

meter and the test circuit before accessing the battery or the

fuses.

Battery and Fuse Replacement

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.

To replace the 10 A fuse, remove the battery, remove the four rear-case screws,

separate the case, remove the 10 A fuse cover, and remove and replace the 10 A

fuse. Re-install the fuse cover.
