Inductive Locating; Apply The Hf Signal - Pipehorn Series 800-H User Manual

INDUCTIVE LOCATING

This method is used when there is no direct access to the target
conductor. It is also helpful in finding conductors with locations
that are unknown.
With the 800-H the High-frequency is induced onto the conduc-
tor. It will only do so when the connection cables have been dis-
connected from the Transmitter.
Starting From a Known Point
Use the following steps to begin tracing a conductor from a
known point such as, a meter, valve, pedestal, or line marker,
where access to the conductor for direct hook-up is not possible
or is prohibited.

Apply the HF Signal

Place the 800-H Transmitter directly over the conductor with the
handle in-line with the conductor, as shown below. Careful align-
ment and placement of the Transmitter will maximize the signal
on the conductor. Turn the Transmitter ON.
Set Up the Receiver
Depending on the depth of the conductor, move 20-30 feet away
from the Transmitter. The deeper the conductor, the farther
away from the Transmitter you must start. Face the Transmitter
and position the Receiver antenna near the ground. Set the Re-
ceiver to receive High-Frequency as explained on page 8. Move
the sensitivity knob clockwise to turn the receiver ON.
