PVC Plastic or Non-Metallic Pipes: A fish tape or plumber's snake must be inserted into
the pipe first. Connect one lead to the fish tape or snake and the other lead to earth ground via
screwdriver.
Connecting the transmitter leads to conductors or shield within the cable will minimize the
bleeding effect or the tracking signal into adjacent utilities in congested areas.
Connecting one lead to a conductor or shield and the other to earth ground via screwdriver
will insure maximum distance. This method can be used in all applications. However, it may
increase the chances of the bleeding effect.
Testing Receiver Batteries
Turn receiver control on and rotate clockwise to the 12:00 position. Turn the transmitter on
to #3 position and pass receiver antenna close to the transmitter. Any indication from the
receiver indicates acceptable battery condition. Refer to the "Maintenance" section for battery
replacement.
Operating Receiver
Turn receiver control knob on and rotate clockwise to the 12:00 position. If optional head set is
to be used, plug headset into receiver jack provided. A peak meter indication will be seen and
a strong tone will be heard when the receiver/antenna is directly over the cable or pipe. The
antenna or T-end should be oriented perpendicular to the path of the subject utility. (See Fig. 1)
Locating Path
Note: The transmitter control knob should initially be set as low as possible to minimize the
bleeding effect in congested areas.
Connect transmitter properly and set output level to #3. Radius the area approximately 10 to 15
feet from the transmitter location with the receiver. Proceed down the path following the peak
meter indication and the tone from the speaker or the headset.
As progress is made down the cable path, gradual increases in the receiver gain control will be
necessary to maintain reception.
The receiver control knob should be adjusted so that the meter needle is at approximately
1/2 scale to insure that any increase or decrease in signal can be detected and accuracy
maintained.
Return to the transmitter and increase the output level as needed for the distance and depth
required.
Determining Depth
Mark the ground directly over the path. (See Fig. 1) Hold the receiver at a 45-degree angle close
to the ground. (See Fig. 2) Maintain this angle and slowly move the receiver away from the path
opposite the handle. (See Fig. 3) The tone will decrease to a minimum and then increase again.
Mark the spot where the signal is at its minimum. The depth of the cable will be the distance
between the two points marked.
