3.2 Tracing De-energized Wires

Connecting Transmitter test leads
1. Connect the green and red test leads to the
Transmitter (polarity does not matter).
2. Using provided test leads, connect the green
wire to a separate ground (metal building
structure, metal water pipe, or ground wire on a
separate circuit) (Figure 3.2a).
3. Connect the red test lead to the wire being
traced. For receptacles, make sure to connect
the test lead to the line (hot De-energized) wire.
For De-energized systems the signal will be
transmitted across all branches of the circuit.
Set up the AT-8000-T Transmitter
1. Press power button to turn on the Transmitter.
2. Verify that the test leads are properly connected; the red
LED voltage status light should be off for De-energized
circuits below 30 V AC/DC.
Note: Make sure to use the separate ground
connection as described above.
3. Select HIGH signal mode by pressing HI for most
applications. The Transmitter will appear as shown in
Figure 3.2b. The LED display will quickly begin to blink.
Note: The LOW signal precision mode can be used to limit
the signal level generated by the Transmitter in order to
more precisely pinpoint wire location. A lower signal level
reduces coupling to neighboring wires and metal objects
and helps to avoid misreading due to ghost signals. A
lower signal also helps to prevent oversaturating the
Receiver with a strong signal that covers too large an
area. The LOW mode function is only used for the most
demanding and precise wire tracing applications.
