Normally, a big capacitor is larger than 3 ohm.\u003cbr\u003e\u003cbr\u003eUsing this theory, we can measure the capacitor is bad\/ damaged or good in condition.\u003cbr\u003eBecause our ESR meter only applies less than 15mV DC or peak to peak on a good\u003cbr\u003ecapacitor, as a result we can use it as in circuit test.
