used if one or more functions fail
or if no functionality is indicated.
It is not permitted to use the
tester during rain or precipita-

A perfect display is guaranteed
only within a temperature range
of 0° to +40°C at relative air hu-
midity less than 80 %.
If the safety of the user cannot
be guaranteed, the tester must
be switched off and secured
against unintentional use.
Safety is no longer guaranteed
e.g. in the following cases:
− obvious damage
− broken housing, cracks in
housing
− if the tester can no longer
