To avoid the canceling effect of the opposing magnetic fields and optimize the transmitted
signal, the conductor to be traced should be separated from the return conductor by utilizing
a remote return path.
The simplest method is to use the 25' test lead to connect to a remote return path, such as
a neutral from another circuit. When identifying breakers, the hot and neutral are already
separated at the electrical panel so the use of the AC outlet adapter is sufficient.

No Signal Canceling
If unsure that the remote return path chosen is a good one, use a multimeter to measure the
resistance between the circuit neutral and the remote return path. If >100Ω, a different return
path should be selected.

Applications

Pre-test Operation

Prior to finding a breaker or tracing a circuit, it is good practice to test the receiver by
holding it near the powered transmitter or inductive clamp. A numeric indication of "99" and
strong audible sound ensures that it is working properly.
Locating Circuit Breakers and Fuses
Applications include identifying the breaker that protects the circuit under test, finding the
correct breaker to de-energize the circuit, and labeling a breaker panel.
1) Connect the transmitter to the circuit that needs to be identified and power it on.
The procedure is the same whether the circuit is energized or de-energized. But, a
much stronger signal is produced using an energized (closed) circuit.
