3.2 Tracing De-energized Wires

Connecting Transmitter test leads
1. Connect green and red test leads to the transmitter
(polarity does not matter)
2. Connect red lead to de-energized line/phase wire (on the
load side of the system). In de-energized mode the signal will
be injected to ALL branches of the circuit, not just between
the outlet and the breaker/fuse as in energized modes.
3. Connect green lead to a separate ground (metal building
structure, metal water pipe, or ground wire / Protective
Ground (PE) on a separate circuit).
ATTENTION: Due to safety reasons this is only allowed in
de-energized circuits. Do not use a ground wire that runs in
parallel to the wire you are going to trace, as it will reduce or
cancel tracing signal.
*Note: If working with energized RCD protected circuits, separate ground connection will trip the RCD.
Set up the AT-8000-TE 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.
