Turn the receiver on and place the A-Frame probes in the
ground parallel to the path of the cable. Be sure to insert
them into the ground. As the transmitter pulses, you should
see the analog needle of the GFL3000 kick in the direction
of the fault. Remember, it is the initial kick you are
watching for, not the rebound kick.
7.
Remove the A-Frame probes from the ground and move it
in the direction of the initial needle kick along the path of
the cable. Re-insert the A-Frame probes into the ground
and repeat the process of observing the direction of the
initial needle kick (See Figure 3).
8.
As you pass the fault, the needle kick direction will reverse.
In other words, as you continue down the path of the cable
and follow the needle kicks, the needle will reverse its
initial direction of kick after you pass the fault. This
indicates a fault is between the last 2 A-Frame insertion
points (See Figure 3).
