Troubleshooting

In case of malfunction during the operation of the meter, the

following steps should be performed in order to isolate the cause

of the problem:

1. Check the battery.

2. Review the operating instructions for possible mistakes in

operating procedure.

3. Check the clamp against a known current source. Use the

voltage function to measure a known voltage (AC and DC).

4. Check the test leads for continuity (voltage and

resistance). Except for the replacement of the battery,

repair of the clamp should be performed only by a Factory

Authorized Service Center or by other qualified instrument

service personnel. Front panel and case can be cleaned

with a mild solution of detergent and water. Apply

sparingly with a soft cloth and let dry completely before

using. Do not use aromatic hydrocarbons or chlorinated

solvents for cleaning.
