Maintenance; Fuse Replacement - BEHA UNITEST Schuko-Fix Bedienungsanleitung

The LED 'Ready' lights up red. If the LED only lights
up weakly then the mains plug should be reversed.
Touch the Contact electrode (6)
Should there be a protective conductor failure then this
will be indicated as in the display. The socket then has
to be checked
Press the Test key (4)
The RCD should trip if it is working properly and if the
correct nominal current has been selected.
Monitoring of the contact voltage occurs both before
and after the test and is indicated by means of the LED
' UB>25V (2). Should the contact voltage be too high
then the push button is automatically locked out (4).
This makes it therefore impossible to trip the RCD.

nual, the instrument needs no special maintenance. If it
should become soiled in the course of daily use, it may be
cleaned with a damp cloth and a little mild household de-
tergent. Never use aggressive cleaners, or solvents.
