7.1 Cleaning

If the instrument is dirty after daily usage, it is advised to
clean it by using a humid cloth and a mild household deter-
gent.
Prior to cleaning, ensure that instrument is switched off
and disconnected from external voltage supply and any
other instruments connected (such as UUT, control instru-
ments, etc.).
Never use acid detergents or dissolvants for cleaning.
After cleaning, do not use the voltage tester for a period of
approx. 5 hours.

service department in order to ensure the specified accura-
cy of measurement results. We recommend a calibration
interval of one year.
