Tone Generator Testers
Generate an audible signal when testing for short circuits, line continuity, or when locating a cable. Use an amplifier (sold separately) to hear the signal. These tone generators have a light signal to verify polarity.
Pocket-Size Telephone Line Testers
Measure voltage and continuity and verify polarity in one- and two-line analog telephone networks. A light signals when there is sufficient current available for proper network operation.
| Measures | Features | Each | |
| Continuity, Polarity, Voltage | RJ11 Plug | 0000000 | 000000 |
Telephone Testing Amplifiers
Use this amplifier with a tone generator or tester to identify a cable without making direct contact with the wire. The tone will get louder the closer you get to the correct cable.
Noise-Filtering Telephone Testing Amplifiers
Block out power-line hum when identifying a cable. Use this amplifier with a tone generator or tester to identify a cable without making direct contact with the wire. The tone will get louder the closer you get to the correct cable.
Adapters for Inline Telephone Line Testers
Attach the included cord to an RJ11 wall outlet to isolate the signals of a telephone line, and use alligator clips to connect your testing device.
