Maximum Method
Detecting coil is horizontal to path of line. Maximum audio signal is directly above line.
Application:
- for cable routing
- for terrain examination
The picture beneath shows the working plane of maximum method.
7.3 Depth determination
For measuring the depth (d) of a conductor!
- first determine the exact path of the cable
- subsequently, place coil of detecting road at 45°C
The minimum audio-frequency signal is heard at the depth “d” at a corresponding distance
from the path of the cable.
