3)
Starting several feet from the transmitter, use a sweeping motion and the back of the
receiver to find the strongest signal location behind the wall, above the ceiling or under the
floor.
a)
If the signal is too strong, reduce the sensitivity range.
b)
If the signal is too weak, connect one lead of the transmitter into the open conductor and
connect the other lead to a remote return path. Then, repeat step #3.
4)
Continue following the highest reading until the signal starts to fall off. This is the location
of the open. Reduce the sensitivity range and use the nose of the receiver to pinpoint the
open on the circuit.
If the open is not found after tracing the length of the run, the conductor may be capacitively
coupled. This condition causes a signal bleed-off onto the other adjacent conductors. To remove
this effect, ground the adjacent conductors and minimize the distance between the transmitter
connection and the open.

Finding Shorts

Applications include determining causes of breakers tripping, fuses blowing, and current leaking
on the ground conductor. The tracer locates the origin of the ground fault or dead-short in these
circuits.
1)
Connect the transmitter to the shorted circuit and power it on.
a)
One lead should be connected to the faulted conductor and the other lead to ground.
b)
If the ground fault is in metallic conduit, then the conduit is the ground.
c)
If possible, ground the adjacent conductors.
2)
Turn on the receiver and use the default maximum sensitivity (
3)
Starting several feet from the transmitter, use a sweeping motion and the back of the
receiver to find the strongest signal location behind the wall, above the ceiling, or under
the floor.
c)
If the signal is too strong, reduce the sensitivity range.
d)
If the signal is too weak, connect one lead of the transmitter into the open conductor and
connect the other lead to a remote return path. Then, repeat step #3.
