Answer: The cable fault tester is used to test power faults, so how does it test high voltage and low voltage? What are the specific steps? Xiaobian will introduce it to you. 1. First, judge whether the cable fault is high resistance, low resistance or grounding. According to this condition, different test methods are used.

The fault distance can be measured by the second or third pulse. Compared with the traditional test method, the advanced point of the second and third pulse method is to simplify the complex waveform in the shock high voltage flashover method into the simplest low voltage pulse short circuit. The fault waveform is very simple, so the interpretation is extremely simple, and the fault distance can be accurately calibrated. 2. When finding the path, add a signal to the cable, then use the receiver to receive the signal, and walk along the path with the signal to determine the path of the cable. 3. Accurate positioning according to the measured distance.

When you hear the loudest sound from the headphone of the pointing device, you have found the location of the fault point. I hope everyone will understand. If you want to work efficiently and efficiently, you are welcome to buy the cable fault tester from Shenzhen Noyafa Electronic Technology Co., Ltd.! .
