Maintenance

5.1 Cleaning

Prior to cleaning, remove voltage tester from all meas-
urement circuits. If the instrument is dirty after daily
usage, it is adviseable clean it by using a damp cloth and
a mild household detergent. Never use acid detergents
or dissolvents for cleaning.
After cleaning, do not use the voltage tester for a period
of approx. 5 hours.

5.2 Calibration Interval

The voltage testers must be calibrated periodically and
checked by our service department at regular intervals
to ensure the specified accuracy of measurement re-
sults. We recommend a calibration interval of one year.

test probes and the LED (7) is not illuminated, proceed
with the battery replacement.
