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.
After that, the leads of the Capacitor should be connected to the Multimeter probes and the readings on the Multimeter must be observed. In the beginning, the resistance will be low and then will gradually increase for a good Capacitor. For a shorted Capacitor, the resistance will low at all times.
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.
As the needle starts with a low resistance value and steadily progresses toward infinity, the capacitor is operational. However, if the needle indicates a low resistance value and remains still, it’s likely that the capacitor has short-circuited and requires replacement.
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.
Look at the capacitance of the capacitor tag capacitor to select the appropriate gear. Let''s take the 25 microfarad capacitor as an example. Adjust the multimeter to the capacitor position. …
