1. The difference between the direct-flash method and the rush-flash method is that the rush-flash waveform often has pulses composed of ball-gap discharges, and the distance from the ball-gap discharge to the There is a certain delay in the fault click-through; 2. Due to the influence of stray inductance, the wave head of the reflected pulse tends to bulge upward, and attention should be paid to positioning the virtual cursor at the starting point of the upward bulge; 3. Make full use of the share amplification function accurately Calibration; 4. The convex starting point of the reflective wave head is sometimes difficult to locate accurately, which often causes the distance measurement value to be slightly larger than the actual fault interval; 5. The fault point must be broken down to measure the distance correctly. An Noyafa Electronic Technology Co., Ltd., the fixed-point test manufacturer of the distance meter.
