How does the cable fault tester calibrate the starting points of the ranging reflected pulse waveform? Today, the editor of the cable fault tester will introduce how to calibrate the starting point of the ranging reflected pulse waveform. Friends who want to know how to calibrate the starting point of the ranging reflected pulse waveform will follow the editor's cable fault tester. ? Today, the editor of the cable fault tester will introduce to you how to calibrate the starting point of the ranging reflected pulse waveform. Friends who want to know more about it, please follow the introduction of the editor. Common low-voltage pulse reflection instruments in cable fault testing rely on the operator to move a ruler or an electronic cursor to measure the fault distance. In actual testing, people are often not sure where the cursor should be positioned to calibrate the starting point of the ranging reflected pulse. The farther the cable fault point is, the smoother the reflected pulse rises, and the more difficult the calibration will be.
In the actual test, the inflection point caused by the reflected pulse on the ranging waveform should be selected as the starting point of the reflected pulse, or a tangent line can be drawn from the front edge of the reflected pulse of the ranging waveform, and the intersection point with the horizontal line of the waveform can be used as the starting point of the reflected pulse. The above is the content of the cable fault tester introduced to you, I hope to bring you some help.
