Auto m a tic a nd Ma nua l G a in
The Rex receiver has the ability to operate in an automatic or manual gain mode. In
the automatic gain mode, the sensitivity of the receiver is adjusted automatically,
based on the strength of the detected signal, to produce a relatively constant and
strong signal strength indication. In the manual gain mode, the user can adjust the
sensitivity up or down to suit different locating scenarios.
Dire c tio na l Indic a tio n
The Rex receiver is equipped with directional indicators (arrows). These visual and
audible indicators help the user locate the pipe or cable by showing which direction
he/she should move in order to get closer to the target. These indicators are not
available in the Sonde mode.
De pth Me a sure m e nt
The Rex receiver has the ability to measure the approximate depth of the target pipe
or cable being traced. When a depth measurement is made, the receiver must be
fully extended and the bottom tip of the receiver must be touching the ground.
Depth measurements should only be made when the directional indication says that
the target is close and the receiver’s signal strength is maximized (peaked) over the
target. Special considerations are required for the Sonde mode.
Se a rc hing fo r a So nde
Once in the surroundings of a sonde, it is important
to differentiate whether you are positioned along
the axis of the sonde (the direction of the pipe) or
off to either side. In the sonde mode, the
directional indication is not functional; the signal
strength is the only indication available.
Rotate the receiver back and forth and move in
the direction that produces the maximum (peak)
signal strength. As the receiver gets closer to the
sonde, the signal strength increases and it will hit a
peak when the receiver is directly over the sonde.
Slowly rotate the receiver to fine tune the peak
signal strength, which will occur when the plane of
the sensors is parallel to the axis of the sonde. For
verification, rotate the receiver 90 degrees and see
