40180 Tone Generator and Amplifier Probe Circuit Finder Kit,Black

40180 Tone Generator and Amplifier Probe Circuit Finder Kit,Black

Q: Do you have to use the transmitter or can it locate passive cables behind a wall without it?

You can locate 60Hz lines behind a wall to some extent, without the transmitter: The probe will make a louder 120Hz buzzing noise as it is moved closer to cables.

Q: If I have both ends of a house wire exposed, how would I hook up to check if I have the correct wire?

You connect the transmitter to a pair of wires in the room, either raw ends or in an RJ11 telephone jack. Turn it on. Turn on the probe and check that the toner is working. Go go to NID, where all the house wiring starts. The tone can be hear is you are near the wire, louder on the outside of the cable, very loud when actually touch the correct pair of wires.

Q: Is it easy for a beginner to use? Does it easily hook up to the wire or do I need to cut into the plastic surrounding the wire?

It's easy to connect and you don't need to cut into the insulator, but the problem I had with the tool is: the signal is so sensitive that I wasn't able to tell if the wire was cut, because all the wires I was testing were in a harness

Q: How many feet will this work for?

i was using it very successfully at over 70 feet. The lines I was tracing were up and over in a building. So i really do not know the exact distance. but it worked great
