Circuit Breaker Identifiers
FEATURES ● The 188FFF is a Fuse and Fault Finder which comprises of two parts : The Receiver and the Transmitter.● The Transmitter, draws a current from the mains supply circuit to which it is connected to. The Signal● Current from the Tx is at about 10kHz. The Transmitter is powered by the mains and requires no batteries.● The 10kHz signal current generated by the Transmitter is then searched(sniffed) by the Receiver to detect the Fuse, Circuit Breaker or the faulty circuit.● The Receiver is a tuned circuit which has it's 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 a bar-graph type Leds.● The more Leds ON, the stronger the signal.● The Receiver uses one 9V battery. SPECIFICATIONS Receiver Tuner circuit mid frequency 10kHz Bar graph leds 9 Battery indicator led 1 On button 1 Off button 1 Buzzer 1 Auto-off(Min) approx 1 ...
