AEMC Instruments 6681 Description:
The system can locate open circuits, shorts, track cables and locate fuses or circuit breakers. It is also 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 to the circuit that is 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. In addition, the transmitter has a self-test function, indicating good transmission between transmitter and receiver. Both the transmitter and receiver units include a flashlight feature that assist the operator when working in dark unlit areas.
The receiver features a sensitive sensor that generates a display proportional to the electric field detected. The variations of this signal, after decoding, processing, and shaping, 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.
