4.6 Tracing Shielded Wires

Shielded wires prevent the Receiver from detecting a tracing signal when following the
standard user instructions. To effectively trace shielded wire, follow these procedures.
If shielded wire is grounded at the far-end:
1. Setup Transmitter in Loop mode by pressing HIGH button for two seconds. Verify that
the Loop LED is ON.
2. Disconnect the ground on the near-end of the shielded wire and connect the shield to
one of the terminals of the Transmitter (polarity does not matter) with a test lead.
3. Connect the second output of the Transmitter to a separate ground.
4. Set the Receiver to De-energized TIP SENSOR mode to trace the shield as described in
section 3.2.
If shielded wire is disconnected from ground at the far-end:
1. Setup the Transmitter in Wire Tracing mode (see section 3.2).
2. Disconnect the ground on the near-end of the shielded wire and connect the shield to
one of the terminals of the Transmitter (polarity does not matter) with a test lead.
3. Connect the second output of the Transmitter to a separate ground.
4. Set the Receiver to a wire tracing mode to trace the shield as described in section 3.2.
