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 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 a
bar-graph type Leds.
The more Leds ON, the stronger the signal is.
The Receiver uses one 9V battery
