4.13 Signal Clamp - Mapping Circuits

The clamp accessory can be used to map loads to the specific breakers on both Energized
and De-energized circuits. There is no need to disconnect the power.
1. Connect the CT-400 test leads to the terminals of the Transmitter (polarity does not
matter) and select HIGH mode.
2. Clamp the CT-400 around the hot (line) wire at the breaker panel.
3. Select Quick Scan mode on the Receiver with the highest sensitivity level.
Scan the face plates of receptacles and wires by touching them with the Tip Sensor of the
Receiver. All the wires, receptacles and loads that the Receiver indicates in the Quick Scan
mode are connected to the breaker.
Note: Expect a relatively weak signal. For best performance, install fully charged high
capacity rechargeable batteries to the Transmitter. Use the "Mapping a circuit using test
leads connection" method if a much stronger signal is required.

*Note: For best results, keep the Receiver at least 3 feet from the Transmitter and its test
leads to minimize signal interference and improve wire tracing results.
