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.
