How to use a multimeter to judge whether the capacitor is damaged?
Usually, a multimeter can be used to check whether the capacitor is damaged. When checking, first turn the multimeter selection knob to the ohm gear RX1k or RX10k, and then alternately touch the two ends of the capacitor with two test pens. If the pointer of the meter deflects to a certain extent and slumps back to the starting position, it means that the capacitor is in good condition; if the pointer does not return to the starting position after swinging, the resistance value indicated by the pointer at this time is the leakage resistance value of the capacitor; If the pointer is deflected to the zero ohm position, it means that the capacitor is short-circuited; if the pointer does not move at all, it may be that the capacitor is broken or failed.
