Individual Wires within bundles
When tracing wires bundled together, it may be necessary to separate them to reduce magnetic
coupling to nearby wires (see p.12).
Conduit
1. Plug the pigtail connector into the transmitter.
2. Attach one of the pigtail connector's insulated clip leads to a separate ground such as a water
pipe. Be sure the ground path you choose is not adjacent to the conduit you wish to trace.
3. Attach the other lead to the "hot" conductor that runs inside the conduit you wish to trace.
The transmitter's LED will blink to indicate it is operating and that the circuit is complete.
4. Turn the receiver's range switch to "Scan-6." Since conduit will frequently cause the signal to
become weaker, turn the receiver's range switch to a higher gain as necessary.
5. Press the receiver's "ON" button and wait for it to calibrate
6. Hold the receiver's tip close to the location where you suspect the conduit runs.
7. Sweep the receiver across large areas until its signal locates the conduit. Narrow down the
location of the conduit by adjusting the range switch (see Figs. 7) and changing the angle of
the receiver.
NOTE: Be sure you are following the "hot" conductor within the conduit and not the ground
path or neutral wire used to complete the circuit. Do not use the conduit if you wish to trace for
the ground connection.
Since the feeder panel may radiate the magnetic field to the nearby conduit, make sure the
probe is always used more than 5 feet (1.5 meters) away from the circuit breaker panel during
this application (see Fig.7).
