Cable tester with tone generator UNI-T UT682D
Product information:
UNI-T cable tester for detecting cables and possible breaks.
Method: Use both the tone generator and the probe to determine where a cable goes and see if it is broken (and if so, where the break is located).
You attach the tone generator to a wire with the crocodile clip and use the measuring probe to follow the wire (the measuring probe will beep louder as you get closer).
This is possible over cabling up to 3000m.
Works on two 9V batteries (incl.)
