1. Comprehensive functions, safe, rapid, and accurate fault testing. The instrument uses low-voltage pulse method and high-voltage flashover method to detect various cable faults, especially for cable flashover and high-resistance faults, which can be directly tested without burning through. If equipped with an acoustic positioning device, it can accurately determine the precise fault location.
2. High testing accuracy, the instrument adopts high-speed data sampling technology with A/D sampling speed of 100MHz, enabling a reading resolution of 1m and a detection blind zone of 1m.
3. High intelligence, test results are automatically displayed on the large LCD screen in the form of waveforms and data, making fault judgment intuitive. It is equipped with a full Chinese menu display operation function, requiring no special training for operators.
4. This cable fault detector has waveform and parameter storage and recall functions, using non-volatile devices, so waveforms and data are not lost after power off.
5. Dual-trace display function, allowing comparison of the test waveform of the faulty cable with the normal waveform, which is beneficial for further fault judgment.
6. Waveform expansion ratio function, changing the waveform ratio to expand the waveform for precise testing.
7. The position of dual cursors can be arbitrarily changed to directly display the direct or relative distance between the fault point and the test point.
8. The propagation speed can be modified at any time according to the different cable under test.
9. Compact portable design, powered by built-in rechargeable battery, convenient for carrying and use.
