6.1
Using the Receiver
6.1.1 Line
Locating
Line locating is when a pipe or cable is being located. When line locating, the receiver should be held with the
display forward, and then swept to the left and right across the suspected direction of the buried line. Note
the compass line direction indicator always points in the direction of the line (active in active modes). The
compass color change from clear to blue when the receiver is in line with the buried line.
The receiver should be kept parallel to the ground – and should not be flipped up at the end of each pass.
See diagram (a).
To establish the direction of the cable – use whatever mode you prefer to locate the line; then switch to
“Peak” mode to confirm the direction. Pinpoint the line – by carefully establishing the exact “Peak” position.
Then (with the base of the receiver on the ground) rotate the receiver through 90 degrees, as you do this the
signal being received will reduce substantially (possibly disappear). Then rotate the locator until you find the
maximum “Peak”. The front of the locator is again facing in the direction of the buried line. See diagram (b).
6.1.2
Depth & Current Measurement
Pinpoint the exact position of the cables as follows:
Locate lateral position of the cable.
Rotate receiver to confirm the direction of the cable (you will see a null response when the receiver is
intersecting the direction of the cable at 90 degrees).
Rotate the receiver back until it is exactly in line with the cable.
