6. Testingofinterruptionsoflivelines(figure C)
To localize interruptions of live lines (e.g. a cable break in a cable reel or defective lamps in a chain of
lights), pass the probe tip
other end of the line. The point of interruption is located as soon as the phase (external conductor) is
no longer indicated by the acoustic signal and the test probe lighting up.
For testing a cable reel, make sure to turn the shock-proof plug by 180° in order to connect both lines
to the phase (external conductor) of a shock-proof socket.
7. Batteryreplacement (figure A)
- Do not apply voltage to the device when the battery compartment is open!
- Remove the battery compartment cover
- Insert new micro batteries (LR03/AAA) into the indicator observing correct polarity (positive pole
first).
- Screw the battery compartment cover
