1 straight red flash flash method and the method of difference is that the red ball flash pulse waveform is often formed gap discharge, and discharge from the ball gap to malfunction Click to wear a certain delay;

2 Due to the impact of stray inductance, often with raised up in the reflected pulse wave head, you should pay attention to the virtual cursor is positioned at the starting point raised upward;

3 full advantage of scaling functions to determine the fine scale;

Raised the starting point 4 of the reflected wave head is sometimes difficult to pinpoint, often resulting in distance slightly larger than the actual value of the fault distance;

5 points of failure must be properly ranging breakdown
