Maintenance

This meter is precise device, Do not attempt to repair or service your meter you are qualified to do so

andhavethe relevantcalibration performance test, andserviceinformation.These products are intelligent

meter, use self-calibrating technology. To avoid the specification error. All components not replaced

except that if is specified.

General Maintenance

Periodically wipe case with a damp cloth mild detergent.Do not use abrasives or solvents.Dirt or moisture

in the terminals can affects readings.To clean the terminals.

1. Turn the meter OFF and remove all test leads.

2. Clean out any dirt that may be in the terminal.

3. Soak a new swap with a cleaning and oiling agent.

4. Work the swab around in each terminal the oiling agent insulates the terminals from moisture

Related contamination.

Battery Replacement

Waring

To avoid electrical or are blast, or personal Injury or damage to the meter, use specified fuses

ONLY in accordance with the following procedure

The meter is powered by a 9V battery (NEDA 1604, 6F22, 006P), Replace battery if the low battery sign

“ ” displayed. Use the following procedures to replace the battery.
