Hold the test magnet (accessory) against
the circle symbol with the label "TEST" on
the instrument housing
Abb. 14: Simulation of the output signal
The test magnet changes the current switching
condition of the instrument. You can check the
change on the signal lamp. Please note that
all connected device are activated during the
simulation.
Caution:
It is absolutely necessary that you remo-
ve the test magnet from the instrument
housing after the simulation.
