There are two ways to tell you whether the capacitor is good or bad

【DESCRIPTION】：1: Measure the capacitance with a digital multimeter: set the gear to the capacitance (select the gear according to the capacitance value you measured). During the test, use two probes to connect the two feet of the capacitance. The meter has a certain value, and then return to the infinity position. Exchange the probes and try again. This time, the size of the data shows a slight error, and then return to the infinity. The capacitance is good, If the appearance of infinite large, clarify the internal open circuit or no capacity.
2: Use a pointer multimeter to touch one foot of the capacitor with a pointer multimeter, and then touch the other with the other. At this time, the needle will rise rapidly and then slowly drop. This is the charging and discharging process of the capacitor. It is stated that the capacitance is good. If there is no change, the AC pen will show the above phenomenon, which is also good, If there is no charge or discharge or the needle does not drop after rising, the capacitance is broken. If it doesn't go down, it will break down inside. If the needle doesn't move, it will be invalid. For large capacitance, use 1x10 or 1x10k for small capacitance.
The above method is not very simple. If you still don't understand, you can contact our engineer: 0086-0755-27299931/+86-13632665518, Yang GONGDING will answer your questions in more detail!
