The transmitter module generates a coded signal that is injected into a powered AC line, and the receiver wand uses this signal to reject noise and correctly identify the correct circuit breaker or fuse wire.
Three testers in one:-
Identify circuit breaker to electrical sockets Trace AC cables in walls Identify AC wires in a bundle
Additional features:-
Microprocessor controller Coded transmission allows easy differentiation of transmitter signal Audible and visual indicators Includes sensitivity adjustment Cable tracing depth to 400mm (15 inches) norminal Receiver Tracing depth for fuse identification to 100mm (4 in) norminal
