INSTRUCTION MANUAL

SETUP

NOTE: The transmitter produces high voltage. Turn the transmitter
off before handling the output leads. Disconnect all wires when
fault locating. Turn the selector knob to the BATTERY TEST
position. The meter should read between 8 and 10.
IMPORTANT: To ensure that the transmitter is producing optimum
signal, connect the red and black leads together and turn the unit
on. Turn the selector knob to position #5. The meter needle should
rise to at least a 10 reading.
CAUTION
Electric shock hazard:
Do not connect transmitter to any active AC circuits.
Failure to observe precaution may result in injury
and can damage the instrument.
FIGURE 1: Transmitter Setup
1. With the transmitter off, connect the red lead to the wire to be located
and the black lead to a good earth ground with the stake provided.
(Refer to Figure 1)
2. Turn the transmitter on and start rotating the selector knob clockwise.
Once you leave the BATTERY TEST position and go to #1, the meter
needle will fall off to near zero. As you increase the output, the needle
will rise slightly with each advancement. Stop when the meter reads
between 4 and 8. The transmitter is now set for maximum efficiency for
this job. If a reading of 4 is not obtainable, reposition the ground stake.
3. Plug the optional handset into the receiver if desired, turn the receiver on
and point the antenna or probe end at the transmitter. A pulsing tone
should be heard and an indication should register on the receiver meter.
NOTE: High pitched tones from the headset may occur if the headset
cord gets to close to the receiver antenna or the receiver battery is low.

OPERATION

Locating Wire Path
With the probe pointed toward the ground, walk completely around
the transmitter location. An absence of tone or null will be detected
directly over the path of the wire. Movement to either side will
cause the volume of tone signal intensity to increase. Follow the
null to determine the wire path. (Refer to Figure 2).
FIGURE 2: Locating Wire Path
Finding Wire Breaks and Nicks
When attempting to find breaks and nicks, you should decrease
the sensitivity of the receiver when pointing it off to either side of
the null. You will be able to notice the charge in signal intensity
immediately. Do not allow the meter to peg or go above 10. This
will greatly help in the fault locating process.
NOTE: The wire must have a path to ground to be successfully
located. These paths exists in a great majority of all direct buried
wires due to insulation imperfections, nicks, and bad splices. If
not, create one by grounding the remote end.
