 Connect the test cables to the test object (see figure 5.36 and 5.37).
 Touch the silver contact electrode of the "TEST" key for at least two seconds.
 If phase voltage is connected to the PE connection, the warning is shown on the
LC display of the installation tester and the buzzer sounds. Further measurements in
the Zloop (L-PE))and RCD functions are blocked.
Warning:
 If the phase voltage is detected at the protective conductor connection (PE), immediately
stop all measurements and make sure that the fault will be eliminated.
Notes:
 The protective conductor connection can only be tested in the Z
