CAUTION
Direct Connection
Direct Connection is the most reliable method of signal application.
• Relatively free of interference, achieves the greatest amount of signal strength
• All frequencies may be used.
• The far end of the utility must be grounded
Connect the red test cord to an existing ground point or an exposed metallic
section of the utility. Place the ground rod approximately 10 feet from this
point, at an angle of 90º to the buried cable or pipe. Push the ground rod into
the ground 8 to 10 inches. Connect the Black test cord to the ground rod.
Plug the Red/Black test cord into the TX OUTPUT JACK. Select the
FREQUENCY. The Power Output Indicator, Load Rate Indicator and the
Frequency will be displayed.
Flexicoupler Connection
The optional Flexicoupler and hard coupler are very easy to use
• Services do not have to be interrupted
• The operation range is shorter than for Direct Connection methods
• The tracing signal can be affected by neighboring cables and pipes.
• The red/Black test cord or the ground rod are not needed for this method.
Successful coupler operation requires an insulated conductor that is
grounded on both near and far ends.
Loop the Flexicoupler around the cable and connect the two ends, or clamp
the hard coupler around the cable. It is important to connect the coupler
around the cable needing to be traced. Connect the coupler around the wire
closer to the outgoing cable not near the system ground. The result will be
a stronger signal. By connecting near the grounding, the range will also be
shorter, and difficulty may arise determining one cable from another.
Plug the coupler test cord into the TX OUTPUT JACK. Always select the
frequency designated by the coupler. The most common is the 82 kHz
FREQUENCY, but coupler are available in multiple frequencies.
Inductive Connection
• This method is convenient to use, and services are not interrupted.
• No test cords or connections are needed.
• The cable or pipe must have good insulation or non- conductive coating,
or the operating range will be short.
Turn the transmitter ON. Select 82kHz Frequency. Place transmitter on its side
as close as possible to the path of the cable or pipe. Align the ARROWS on
the SIDE OF THE TRANSMITTER in line with the cable or pipe. First, locate the
broad transmitter Null, then move toward the expected cable path
while looking for the signal carried by the cable.
Start tracing the path with the receiver 25 feet from the transmitter. Search
in the 90º zone as shown right. Locate the cable or pipe, and follow the
path. If the signal becomes weak, move the transmitter to a point 25 feet
behind the last strong signal, and continue searching.
Always turn transmitter OFF before connecting
and disconnecting test leads
Do not connect to live or
energized power cables
