Path Fault:
It consists of a transmitter, receiver, induction probe, and potential difference detection frame. The instrument uses electromagnetic induction to trace the route and measure burial depth of optical cables and cables, and uses the potential difference method to locate faults in optical cables and cables. It is suitable for locating the route, burial depth, and insulation fault points of various optical cables and cables with metal conductors (wire pairs, sheaths, shielding layers). It is a dedicated line fault tester for postal and telecommunications systems, as well as railway, mining, oil field, airport, shipping, and other units.

Main Features:
1. High precision cable fault detector manufacturer has complete functions, and tests faults safely, quickly, and accurately. The instrument uses low-voltage pulse method and high-voltage flashover method for detection, can test various faults of cables, and directly test flashover and high-resistance faults of power cables without burning through. If equipped with an acoustic point locator, the fault point position can be accurately determined.
2. High testing accuracy. The instrument adopts high-speed data sampling technology with a reading resolution of 1m. High intelligence. Test results are automatically displayed on a large LCD screen in small text and data, making fault judgment intuitive. It also has a menu display operation function, requiring no special training for operators.
3. Has waveform and parameter storage and recall functions. Uses non-volatile devices, so waveforms and data are not lost after power off.
4. Has dual-trace display function. The test waveform of the faulty cable can be compared with the normal waveform, which is helpful for further fault judgment.
5. Has waveform expansion ratio function. Changing the waveform ratio can expand the waveform for precise testing.
6. Control measurement cursor, can automatically search along the line, and automatically stop at the inflection point of the fault waveform.
