188 FFF Circuit Breaker Identifier


The 188FFF Circuit Breaker Identifier is a Fuse and Fault Finder which is comprised of two parts: Transmitter and Receiver.

The Transmitter generates a signal current whose frequency is approximately 10kHz. The 10kHz signal current is then searched (sniffed) by the Receiver to detect the fuse, circuit breaker or faulty circuit.

The Receiveer is a tuned circuit which has its center frequency tuned to about 10kHz. The sensor is located in the tip of the Receiver. The amplitude of the received signal is shown on an LED bar-graph.
