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.
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.
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.
For a good Capacitor, every attempt of the test should show a similar result on the display. If in the further tests there is no change in the resistance, then the capacitor should be replaced as it is a dead one. At first, the Capacitor must be disconnected from the circuit board and then it should be discharged completely.
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.
To test a capacitor with a multimeter, you need to follow these steps: Disconnect the capacitor from the circuit. Before testing a capacitor, you need to make sure that it is not connected to any power source or other components in the circuit. This will prevent any damage to the multimeter or the capacitor. Discharge the capacitor.
