Using the Transmitter in Induction Mode

General Information

Induction is a quick and simple way to apply a signal to a utility without the
need to make any physical connection to it. The transmitter uses an internal
aerial to transmit the signal to the utility.

Work at least 10 m/33 ft away from the transmitter to avoid airborne
☞
signals. Reposition the Transmitter if necessary.
Coupling efficiency is best at 33 kHz.
☞
The signal can also apply itself to other utilities within close proximity
☞
to the transmitter, depending on their depth and direction.
To increase the battery life and to reduce the possibility that the
☞
signal is applied to adjacent utilities, reduce the signal output.
The Numeric Peak Indicator can be used to indicate multiple utilities
☞
or to assist tracing. The utility with the maximum value is typically the
one closest to the transmitter or the one directly connected to.
