The first method is a visual inspection. The second method is using a capacitance or multimeter to verify its capacitance value with a given tolerance. The last one is by measuring the ESR value of the capacitor. Some of the above methods are applicable for off and in circuit testing as well.
However, it doesn’t come without faults. Capacitors can suffer from leakage current, which is the result of imperfections in the oxide layer. Plus, capacitors with leakage current can become a big problem in your circuits. Luckily, there’s an easy solution to this problem. All you need is a capacitor leakage tester!
Identification: Electrolytic capacitors can leak their internal electrolyte when they fail. This leakage can appear as a wet or crusty residue around the base of the capacitor or seeping from the top. Consequences: The leaked electrolyte can be corrosive and may damage the circuit board or other components it comes into contact with.
Follow the following step to check if capacitor is bad or good. Take the MESR-100 and turn it on. Take your capacitor and discharge it properly through resistance material. Discharging a capacitor can be done by shorting the legs of the capacitor by any high resistance substance available to you. Connect the discharged capacitor to the ESR meter.
For the modern capacitor, we used the leakage tester to apply approximately 400 volts, and the leakage was around 25 microamps. That’s a small leakage, so the modern capacitor passed the test. On the other hand, we applied the same 400 volts to the old-fashioned capacitor, and we found it passing through 10x the current.
A simple capacitor leakage tester can test leaky electrolytic capacitors within the range of 1uf to 450uf. Also, it’s capable of testing large start-and-run capacitors and smaller 1uf capacitors with 10v ratings. However, once you grasp the timing cycle, you could test below 1uf (0. uf) and higher than 450uf (up to 650uf).
