If you can no longer trace the path, even with the GaIn set to maximum, connect the tranSmItter to
the far end of the path and trace back to the point where you lost the signal.
Mark the straight sections of the path every few feet. Mark sharp curves, loops, and cable bundles
every few inches. Sharp changes in the path cause the
reCeIver Peak and Null indications to behave
differently than when tracing a straight path. Practice on the path that you know has turns and laterals
in it. This will help you to recognize the conditions within the field.
Trace the path by walking away from the
tranSmItter at a moderate pace. Move the reCeIver to the
left and right while walking, following the Peak indications.
As you trace the path, the Peak meter reading may slowly fade as you move away from the
tranSmItter. Press and release the GaIn buttons as needed to compensate for changes in level (higher
or lower). One of the following may occur:
a) a JunCtIon wHere tHe SIGnal dIvIdeS and GoeS Several dIreCtIonS.
B) a BreaK In tHe CaBle or SHIeld.
C) a CHanGe In tHe deptH of tHe CaBle or pIpe.
d) an InSulated pIpe fIttInG.
e) a SlaCK loop of CaBle.
Move the reCeIver left to right across the cable path. When the reCeIver is directly above the cable or pipe,
a Null (lowest meter reading and lowest audio tone) will occur. When moving the
reCeIver to left or right
of the Null point, the meter reading will rise to a maximum point (Peak). The audio tone will also be at its
highest pitch. When the
reCeIver is moved beyond the Peak, the meter reading will begin to fade.
Trace the path by walking away from the tranSmItter at a moderate pace. Move the reCeIver to the
left and right when walking, following the Null indications.
It is expected that in areas of distortion and interference the Null locating mode will have a greater
error rate than the Peak locating mode.
