Tracking weak-signal cables (two-pole application)
Note: For the test all wires in the cable must be voltage-free.
If the two-pole method is used for multi-core cables, the received signal at the receiver can be
affected by closely spaced supply and return lines. Eventually the magnetic field can’t spread
enough in this case to be received correctly. If necessary, use a different line as the return line,
which you lay at a distance of min. 2 meters parallel to the target line. In this way, the magnetic
field can spread further and make better locatable signals for the receiver. For this simulated return
line, you can use an extension cord or other conductor.
Through this particular application conductors in damp, plastered or opaque walls, which are
normally hard to track, can be easily located.
Connect the red wire of the transmitter with a cable to be searched, and the black cable with the
simulated return line. Now search the strongest signal with the receiver to locate the conductor.
By changing the transmitter level of the transmitter from 1 to 3, the receiver depth can be changed
by a factor of x5.
