Tracing Non-Metallic Pipes And Conduits; Tracing Shielded Wires - Ampro AT-6010 Serie Manual De Usuario

4. SPECIAL APPLICATIONS

4.5 Tracing Non-Metallic Pipes and Conduits

The Transmitter can indirectly trace plastic conduits and pipes using the following steps:
1. Insert fish tape or wire inside the conduit.
2. Connect the Transmitter with the red test lead to the fish tape and the green ground wire
to a separate ground (see section 3.1 for further set-up instructions).
3. Turn on the Receiver and trace the conduit. Tracing mode is automatically activated.
4. The Receiver will pick up the signal conducted by the fish tape or wire through the conduit.

4.6 Tracing Shielded Wires

Shielded wire prevents 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. Switch the Transmitter to Loop mode by short press of On/Off button. 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. Turn on the Receiver and trace the shield. Tracing mode is automatically activated.
Figure 4.6a: Tracing a shielded wire grounded at the far-end
If shielded wire is disconnected from ground at the far-end:
1. Connect the Transmitter directly to the wire as described in section 3.1.
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. Turn on the Receiver and trace the shield. Tracing mode is automatically activated.
