A few small knowledge to use the cable fault tester Cable fault tester manufacturer Cable fault tester is mainly composed of three parts: flash measurement, tracing and positioning. It can be used to detect low resistance, high resistance, short circuit, open circuit and leakage of various cables The positioning consists of three parts. It can be used to detect low resistance, high resistance, short circuit, open circuit, leakage fault and flashover fault of various cables, and can accurately detect the fault location, cable length and cable buried path of underground cables.
The cable fault tester has the characteristics of accurate test, high degree of intelligence, wide adaptability, stable performance and lightness and portability. The instrument adopts Chinese character system, high-definition display and friendly interface. The operation method of the cable fault tester The multiple pulse method fault test waveform is easy to judge and has high accuracy, but if you want to obtain an ideal waveform that is easy to interpret, you need to master certain skills.
8 little knowledge that you need to know when using the cable fault tester 1. The cable fault tester has the functions of wave open and parameter storage and recall. Using non-volatile devices, the waveform and data are not easily lost after shutdown. 2. Control the measurement cursor, which can automatically search along the line and stop automatically at the inflection point of the fault waveform.
3. The cable fault tester can change the position of the double cursor at will, and directly display the direct distance or relative distance between the fault point of the cable instrument and the test point. Fourth, the cable fault tester has the function of waveform expansion ratio. Change the waveform scale and expand the waveform for testing.
5. High test accuracy. The instrument adopts high-speed data sampling technology with a reading resolution of 1m. High degree of intelligence.
The test results are automatically displayed on the large-screen LCD screen with small size and data, and the fault diagnosis is intuitive. It is also equipped with a menu display operation function, which does not require special training for operators. 6. Complete functions, low risk of test failure, fast and accurate.
The instrument adopts low-voltage pulse method and high-voltage flashover method to detect various faults of cables, and can directly test the flashover and high-resistance faults of power cables without burning through. If equipped with a sound point meter, the location of the fault point can be accurately determined. 7. The cable fault tester has dual trace display function.
The test waveform of the faulty cable can be compared with the normal waveform, which is conducive to further judgment of the fault. Eight, the cable fault tester also has a printing function. Print and archive the test results.
