TRANSMITTER POSISTIONS:
Amount of signal transmitted into buried pipe. (fig. 1)
1.
Almost none
–
when TRANSMITTER

is perpendicular to pipe.
2.
Very small signal.
3.
Maximum signal when TRANSMITTER is
parallel to pipe and over it.
4.
Very strong when TRANSMITTER is
parallel to pipe and close to it.
Amount of signal detected by RECEIVER.
(Fig. 2)
1.
Minimum signal when RECEIVER is
perpendicular to pipe.
2.
Very small signal with RECEIVER in this
position.
3.
Maximum signal when RECEIVER is over
and parallel to pipe.
4.
Very strong signal when RECEIVER is
parallel to pipe and close to it.
LOCATING UNKNOWN PIPE USING THE LOCATOR INDUCTIVELY
(WITH HANDLE)
The pipe or cable under surveillance should be approached at an approximate right angle to the assumed
direction of its course. As the pipe or cable is approached and crossed, an increase in audio and visual
indications will be noted from the RECEIVER. The maximum indication shall be when the
TRANSMITTER is directly over the object. Once the pipe or cable is found, the SENSITIVITY control
can be readjusted to govern the amount of signal indication received. It will originally be noted that the
signal indication over a buried pipe is very wide. By reducing the setting of the SENSITIVITY control, the
width of indication can be narrowed and pipe location pinpointed. The effectiveness of your locator is
