If the dual-pole application is carried out on multi-wire cables ( e.g.
NYM 3 x1.5mm2 ), the location depth is widely limited. This is because
the go-and-return lines are installed very closely. And as a result, a
strong distortion of the magnetic field occurs. The electro-magnetic field
may not develop at the bottleneck. This limitation can easily be
eliminated when using a separate conductor as the return line. This
separate conductor allows a larger spreading of the electro-magnetic
field. Any conductor or cable reel can be used as separate return
conductor.
When tracing the conductors, make sure that the distance between
the feeder line and the return line is larger than the location depth. In
practical applications, this amounts to approx. 2.0 meters.
For this application, humid walls, plaster, etc. have only an
insignificant influence on the location depth.
Requirements:
The current circuit must not be live.
Connect the transmitter in compliance with Figure 18.
The distance between the feeder line and the return line must be at
least 2.0 to 2.5 meters or more.
Proceed as described in the application example.
Note:
Increasing the transmission level from level 1 to level 3 with the
" " button increases the detecting distance of the receiver by
a factor of about 4.
Setup of the receiver: manual mode, minimal sensitivity. If necessary,
adjust the sensitivity of the receiver according to the actual condition
during detection.
Max. tracing depth: about 2 meters
