NOTE: Due to varying installation techniques, the signal might be strong on more than one
wire on the same phase and AC interference or computer data buzz may be present.
Scan each breaker wire by pointing the antenna at the wires. The wire in question will have
a distinct NULL (absence of tone) when the antenna tip is on the subject wire with tone on
either side. (See Fig. 04)
Check signal strength on each subject wire by sliding the antenna in and out along each
side of these wires. The loudest signal will be received when the wire is approximately one
inch from the tip of the antenna. (See Fig. 05) Choose the loudest, clearest conductor and
with the antenna still held against the suspect wire, turn the breaker off. The signal will
cease, positively identifying that breaker.
CAUTION: DO NOT TURN OFF BREAKER IF CONNECTED TO EQUIPMENT THAT CANNOT BE
INTERRUPTED.
To identify the phase feeding the breaker in question, scan all phases entering the breaker
box. Tone will be heard along the sides of the phase carrying the signal with a null directly
over it. (See Fig. 06)
G. Pinpointing Drill Sites
Set up the 508ST as described in Figure 01 and attach to the nearest receptacle. Locate
and mark the path of any signal near your drill site. If you have reason to believe that other
installations are present near your drill site, use procedures outlined in Section 2C, Locating
and Tracking Buried Wires.
The signal generated by the transmitter can be detected through walls and ceilings. To
pinpoint the transmitter's location (specific spot), wrap the alligator clip leads around the
508ST, short leads together, turn transmitter on and secure it to the opposite side of the
wall or ceiling with tape. Scan the wall with the antenna flat against the wall. (See Fig.
07) The peak signal will be heard when the antenna passes directly over the transmitter
location.
H. Determining Which Receptacles are on Specific Circuits
Set up 508ST as outlined in Figure 01 and radius adjacent outlets with antenna. You will
have a tone at the receptacle /outlet that the circuit in question is on. If a clear signal is not
received, that outlet is not part of the circuit you are transmitting from.

I. 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 (Fig. 03).
J. Locating Hidden Receptacles
To locate receptacles that have been covered up by
drywall, attach one transmitter lead to the wire
