Cable Fault Locator
The Biddle 435F identifies and/or locates opens, shorts, high resistance splices, wet splices, sheath damage, split cable pairs and resplits, water migration, taps, connectors, change of insulation, amplifiers, repeaters, load coils, stubs, and capacitor networks.
Features
- Primarily for use on twisted-pair telephone cables
- May also be used on multi-conductor control cables and power cables
- Test a single line
- Compare a good cable pair with a faulty pair, balance a good pair with a faulty pair showing the algebraic difference
- Transmit on one pair and receive on another pair to prove out splits and resplits
