Transmitter Use

Induction

The Transmitter has an internal aerial that will
induce a signal onto a line (or lines) directly below
it, without the need for access to the line.
Generally, induction can only be used to depths of
2 m (6 ft).
Procedure
Switch on the Transmitter and place it directly
above the target line (refer to the relevant
Transmitter section for correct orientation).
Set Receiver sensitivity to mid-way and start
locating line at least 10 paces away from the
Transmitter.
Mark the ground where each peak response is
detected by the Receiver.
Note: Induction cannot be used to apply a signal to
a line below reinforced concrete.
The Transmitter signal may be detected directly
and not from the target line.
To check, point the Receiver directly at the
Transmitter. If the Receiver signal strength
increases, either reduce the transmitter power or
increase the distance from the Transmitter.
If the Receiver signal strength decreases, the
received signal is from the buried line.

Direct Connection

Suitable for use on continuous tracer wire, water
and gas distribution systems, a telecom cable, and
pipelines at a CP test or other access point.
Warning
Should only be used on a power cable sheath
by qualified personnel.
Procedure
Plug the Connection Cable into the Transmitter
and to the target line. If necessary clean off paint,
rust or scale to ensure good connection.
Clip the ground cable to an independent grounding
point a few paces away and preferably at right
angles to the probable route of the target line. Do
not attach ground to water pipe or buried line
which could carry the signal.
