● 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 is 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
● The more Leds ON, the stronger the signal.
● The Receiver uses one 9V battery.
