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.
Every attempt of the test should show similar result on the display for a good capacitor. If there is no change in the resistance in the further tests, the capacitor is dead. This method of testing the capacitor might not be accurate but can differentiate between a good and bad capacitors.
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.
So let's start: A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. By taking the capacitor's resistance, we can determine whether the capacitor is good or bad. To do this test, We take the ohmmeter and place the probes across the leads of the capacitor.
If there is no movement of the needle or the resistance always shows a higher value, the capacitor is an Open Capacitor. This test can be applied to both through hole and surface mount capacitors. The method described here is one of the oldest methods to test a capacitor and check whether it is a good one or a bad one.
ESR stand for equivalent series resistance. What happens to a bad capacitor is that its ESR value changes. The change in ESR is totally helpful when determining with 100% sure if the capacitor is bad or good. Usually a bad capacitor can doge the visual inspection method as well the capacitance measurement method.
