TW-82P TRANSMITTER

INDUCTIVE LOCATING

Inductive locating is most effective with
the Transmitter straddling the utility as
illustrated, with the utility perpendicular to the
Transmitter's batteries.
If the utility direction is unknown, place
Transmitter on the ground, power on,
and sweep the Receiver a complete
360º around the Transmitter, keeping
at least a 25-foot (8-meter) distance
between the Transmitter and Receiver.
If unsuccessful, move the Transmitter
to another location. When located, the
Receiver's azimuth indicator will show the
direction of the utility.
In inductive mode, the Transmitter's LCD
will not display Signal Current. When the
conductive tracing cables are plugged in, the
Signal Current display will illuminate.

CONDUCTIVE LOCATING

1. Place the Transmitter on the
ground and turn it off.
2. Connect the Conductive Tracing
Cables to the Transmitter.
3. Push the Ground Rod into
the earth at a 90º angle to the
direction of the utility.
4. Connect the red clamp to the non-
energized utility.
5. Connect the black clamp to the Ground Rod.
Be sure not to place the wires over any other
utility.
6. Turn Transmitter On.
7. With Receiver in hand, move at least 25 feet
(8 meters) away from the connection point.
8. Sweep the Receiver in a circle around the
connection point.
9. Using information provided on the display,
find the areas that need to be traced and analyze the
situation in more detail to find the buried utility.
