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.
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 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.
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.
A motor with a defective capacitor either hums before starting or starts with a clearly audible hum. These are clear signs of a loss of capacity and thus a defective capacitor. You should be very careful with this type of test as there is a great risk of injury. Above all, never test saws or lawnmowers, in this way.
Next, make sure that the two terminals of the capacitor are in contact with your leads by pressing the probes firmly against them. The meter should indicate a small but finite resistance value, typically in the range of 0-100 ohms. If the reading is higher than 100 ohms, it may be an indication that the capacitor has failed.
