Knowing these 8 points, the cable fault tester will be handy. The cable fault tester is composed of three parts: flash measurement, tracing and positioning. It can be used to detect low-resistance, high-resistance, short-circuit, open-circuit, leakage faults of various cables, and knowing these 8 points will be handy when using the cable fault tester. Most of the composition. 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.
It has the characteristics of accurate test, high degree of intelligence, wide adaptability, stable performance and light weight and portability. The instrument adopts Chinese character system, high-definition display and friendly interface. The fault test waveform of the multiple pulse method is very easy to judge and has high accuracy, but to obtain a more ideal and easy to interpret waveform, it needs to master certain skills.
Knowing the following 8 points, the use of the cable fault tester will be handy. First, 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. Second, the test accuracy is high.
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. 3. Complete functions, low risk of test failure, fast, 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, it can accurately determine the location of the fault point. Fourth, the cable fault tester has a 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. 5. 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.
6. Control the measurement cursor, which can automatically search along the line and stop automatically at the inflection point of the fault waveform. 7. The cable fault tester has the function of waveform expansion ratio. Change the waveform scale and expand the waveform for precise testing.
Eight, the cable fault tester also has a printing function. Print and archive the test results. For more cable fault tester usage skills, please consult Shenzhen Noyafa Electronic Technology Co., Ltd.
