Circuit Breaker Identifiers

188 FFF - Standard Electric Works Co., Ltd (SEW)

● The 188FFF doesn't have the function of the sensitivity adjustment.
If the customers need the sensitivity adjustment function, plase refer to other models.
● 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.
