Connect the optional "Commander" test plug (044149) to the test object (see figure C.4).
Touch the silver contact electrode of the "
TEST
" key at the "Commander" for at least one
second.
If the phase voltage is detected at the PE connection of the "Commander", the LEDs of the
"Commander" will light yellow. In addition, the
warning is shown on the LC display of
the installation tester and the buzzer sounds. Further measurements must be stopped
immediately!
