Textron Company GREENLEE 501 Tracker II Manuel D'instructions page 6

Metallic Pipe or Conduit: Connect one lead to the pipe or conduit and the other
lead to earth ground via screwdriver.
Gas Pipes: Connect one lead to the "IN" line of the gas meter and the other lead to
the "OUT" line.
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.
