To avoid RCD tripping a test has to be carried out between L and N during

approx. 5s. Immediately afterwards, voltage testing between L and PE

can be carried out without RCD tripping.

5.5. Maintenance

When using voltage testers in compliance with the instruction manual, no

particular maintenance is required. If functional errors occur during

normal operating, our service department will check your instrument

without delay.

Prior to cleaning, remove voltage test from all measurement circuits. If

the instruments are dirty after daily usage, it is advisable to clean them 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.

The voltage testers must be calibrated periodically and checked by our

service department at regular intervals to ensure the specified accuracy of

measurement results. We recommend a calibration interval of one year.
