and meter reading, turn down sensitivity slowly until
meter goes to zero.
If you can turn the front knob more than l/4th turn
without an increase in sound and meter reading,
turn the sensitivity knob up from 7 to 8 and try again,
going through the null area making sure it does not
exceed l/4th turn. You may need to readjust the
sensitivity knob to give you a zero reading at the
balance.
CAUTION: Keep away from cars, fences and metal
objects during this procedure.
You are now ready to locate. Crossing over buried
metal causes an increase in sound and meter
reading.

CONDUCTIVE TRACING (without handle)
The most satisfactory method of tracing when you need to trace
an individual pipe when another pipe is nearby is CONDUCTIVE
tracing. In the CONDUCTIVE mode, the transmitter energizes the
pipe through direct connection. Before attaching the ground rod
clamp to the conductor, clean the conductor with a wire brush
(this creates a good metal-to-metal contact).
After cleaning, plug the jack into the transmitter and secure the
clamp to the pipe or non-energized cable. Place the transmitter
in an upright position and as far away from the pipe as possible to
the side opposite any other lines. As far away as possible means
it will be at 90”.
If you are working in an area with several other conductors near
the pipe or cable you want to trace, place the ground plate as
close as possible to the point at which you fasten the clip to the
pipe or cable. This will reduce the signal strength and reduce the
amount of signal induced into another nearby conductor, giving
a more concentrated signal in the pipe or cable you are tracing.
Never stretch the ground plate across a conductor running parallel
to the pipe or cable you are tracing, because even if you are
not hooked up to the conductor you crossed over, the signal has
