Operating Principle
Figure 13:
NOTE : Switching sensitivity between Level 1 and Level 3 increases the sensitivity by a factor of 5.
Setup: manual mode, minimal sensitivity. Maximum tracing depth 2.0 m
5.14 Following lines with higher location depth (Double-pole method)
If the double-pole method is used on multi-core cables, the location depth is limited. This is because the
signal injection and return lines are installed close together, causing a distortion of the magnetic field. To
overcome this limitation, a second, separate conductor may be used as the return line. Any conductor
outside the multi-core cable, or a separate cable reel can be used.
When tracing the conductors, special care must be taken to ensure the distance between injection and
return line is larger than the location depth. In practical applications, this amounts to approx. 2.0 m.
The circuit under test must not be live
Connect the transmitter as shown in figure 14.
The distance between injection and return line must be 2.0 m or more.
