If circumstances permit, it is best to have a good circuit board that is the same as the plate to be repaired as a reference. Then, using the double bang VI curve scanning function of the tester, the two plates are tested for good and bad contrast. The starting comparison test point can start with the port of the board, and then the testers is especially a comparison test of the capacitor. This can make up for the multimeter online difficult to detect whether the capacitance leakage defects.
