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.
