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 Receiver is a tuned circuit which has it’s center frequency tuned to about 10kHz.
The 188 FFF 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.
