The behaviour of the receiver when locating varies according to
the application.

must start a measurement. During the measurement, the current
noise level is displayed both numerically and as a bar as well as
various minimum noise levels.
Pipe location
As soon as a search coil is connected, the receiver automatically
switches to pipe location and performs permanent measurement.
The field strength is displayed on the display both numerically
and as a bar.
A signal that varies in pitch depending on the field strength is
transmitted to the connected headphones.
