Singe-Pole Measurement:
The cable detector can follow a signal in interrupted
circuits as well by using a high-frequency input signal.
This method makes it possible to find cable breaks,
cable knots, loose outlets, etc.
The device is connected to a cable. The reference
potential is implemented through a known earth poten-
tial (water line, heating pipe, etc.).
Detection depth is 0 – 2 metres, depen-
ding on the wall material.
The applicable safety provisions for work
with voltage must be complied with.
Two-Pole Measurement:
Two-pole signal tracing is used for correctly connec-
ted electrical circuits without an error point or for loca-
lising fuses, line courses, etc. It can be performed on
powered-down or live cables. The transmitter is volta-
ge-proof up to 400 V.
The connection must always be between phase (L1)
and neutral (N) conductora. When the protective con-
ductor (PE) must be used, proper function of the pro-
tective conductor must be assured. Advance tests are
not required.
If the current error protection switch is trig-
gered when the transmitter is connected,
a low error current is probably already pre-
sent and causes it switch to trigger
together with the test current. Have the
system checked by an electrician.
The applicable safety provisions for work
with voltage must be complied with.
Detection depth is 0 – 0.5 metres, depending on the wall material. Switching of the signal
level from level I to III increases the signal range by about five times its value.
