Troubleshooting & Maintenance

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 batteries.

2. Review the operating instructions for possible mistakes in operating

procedure.

3. Check clamp against a known current source.

4. Check test leads for continuity (voltage and resistance).

Except for the replacement of the batteries, 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.

The meter is powered by two 1.5 V AAA batteries. Replace batteries as

soon as N symbol is displayed.

1. Turn meter off. Disconnect and remove the test leads.

2. Position the meter face down. Remove the two screws and lift off rear

case.

3. Replace the batteries.

4. Reassemble the case.
