Operating Recommendations
When using Rex, 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 stake 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.
