When using the Rex Pipe and Cable Locator, follow these tips and recommendations
to improve and facilitate your locating experience:
1) Whenever possible, use the conductive mode. It provides the strongest and best-
coupled signal.
2) When operating in conductive mode:

Try to bury the ground steak on a line perpendicular to the utility to be traced.

Verify that a good circuit has been established by:

Checking the output current from the transmitter.

Manually adjusting the output power to affect the output current.

Making adjustments to the conductive clips to improve the connection.
3) When operating in the inductive mode, place the transmitter antenna (located
inside the handle) over the buried cable or pipe in the direction indicated by the
label (perpendicular to the suspected direction of the pipe or cable).
4) If using the inductive clamp mode, place the clamp so that it completely
encircles the desired cable or pipe. Make sure the clamp can fully close so that
both ends touch.
5) When operating in the passive mode, be aware of your surroundings and possible
interference from overhead power lines, other buried cables, pipes or utilities
carrying 50 or 60 Hz signals, and nearby transformers or substations.
6) In all operating modes, always set the gain at the minimum setting that shows a
clear peak over the target. Optimum results will most likely be obtained with a
signal strength reading between 200 and 800. A consistent reading of 995 or
higher indicates the signal is too strong and the receiver gain and/or transmitter
power should be reduced.
