FINDING CIRCUIT BREAKER
Use the tip of the Sniffer to scan the circuit breakers. Please note that the Sniffer is designed to be held vertically for the vertical circuit breakers and horizontally for the horizontal circuit breakers.
MAKE SURE ALL THE CIRCUIT BREAKERS ARE ON
For example, start scanning from the top left row, then go down etc.
But you can scan the breakers in any order. While you are scanning, observe the bar-graph and listen to the buzzer.
FINDING EARTH FAULT
To find an earth fault or the trace faulty wire, you must connect the transmitter in serie with the fault. For example, if you have a short between Line and Earth, but you don't know where the short is.
Connect the Transmitter, using and adaptor, in series, in the line. If the Protection device trips, then you will have to bypass the protection device for the duration of this test. Use the optional leads for this use.

The 188FFF is a Fuse and Fault Finder which comprises of two parts : The Receiver and the Transmitter

The Transitter draws a current from the mains supply circuit to whcih it is connected to the Signal Current from the Tx is at about 10 kHz. 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 on 9V battery
