F Set / Cable Pair Identifier


The set comprises of two main items, a transmitter and search probe. The transmitter is connected to the cable to be traced via either crocodile clips or a RJ11 plug. This connection provides the tracing signal which the probe can then detect. The probe is activated by a push button switch. A warble tone will be heard when the tip of the probe is over the wanted cable or pair. The new tone on short feature gives confirmation of the identified pair by triggering an audible buzzer at the transmitter when the pair is shorted together.
