The AEMC 6681 cable locator detects hidden telecommunications cables, data cables, electric power supply cables, and metal pipes during modification or maintenance work on installations of category III or lower, at voltages of 300V or less with respect to ground. The system can locate open circuits and shorts, trace cables, and locate fuses or circuit breakers. The instrument is a portable system that includes a transmitter, a receiver, and accessories. The transmitter and receiver both have a large back-lit LCD and large keys.

The transmitter applies a modulated AC voltage to the circuit to be located, which creates a proportional alternating electric field. The transmitter is also an AC/DC voltmeter; the display of the measured voltage is accompanied by a symbol warning of the presence of a voltage. The transmitter also has a self-test function, indicating good transmission between transmitter and receiver. Both the transmitter and receiver units include a flashlight feature.

The receiver features a sensor that generates a display proportional to the electric field detected. The variations of this signal enable the user to determine the location of underground cables and pipes, and detect any faults in them. The receiver also includes a buzzer that changes pitch as a function of the strength of the detected signal.
