The Amprobe AT-6000-T Wire Tracer Transmitter works on Energized and De-energized circuits up to 600 V AC/DC in Category I through Category III electrical environments. Transmitter signal modes:

The HIGH mode function is recommended for most wire tracing applications on Energized and De-energized circuits including breaker location. This function will be used the majority of the time.

The LOW mode function is only appropriate for the most demanding and precise wire tracing applications, as it limits the signal level generated by the Transmitter in order to pinpoint the wire location more precisely. A lower signal level reduces coupling to neighboring wires and metal objects, which avoids mis readings due to ghost signals. A lower signal also prevents oversaturating the Receiver with a strong signal that covers too large of an area.

The loop mode is initiated by pressing and holding this Hi button for two seconds. It should be used when working with closed loop De-energized circuits, such as shorted wires, shielded cables or De-energized wires that are grounded on the far-end.
