G. Determining Which Receptacles are on Specific Circuits
Set up 816T as outlined in Figure 01 and radius adjacent outlets with
antenna. You will have a tone at the receptacle/outlet if it is in the
circuit. If a clear signal is not received, that outlet is not part of the
circuit you are detecting.
H. Locating Alarm, Sound & Computer Wires
To locate other wires, it is best to disconnect the wire in question and
directly attach only one transmitter lead to the subject wire, letting the
other lead hang. Trace the path as outlined in, then trace the part of
wire.

J. Locating Hidden Receptacles

transmitter lead to the wire at the breaker and let the other lead hang.

once the tone get closer to the end of the wire.
