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.
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.
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.
Check the multimeter reading. If the capacitance reading on the multimeter is close to the value printed on the capacitor itself, the capacitor is good. If it’s significantly less than the value printed on the capacitor, or zero, the capacitor is dead. Know which caps function or fail in a batch.
Discharge your given capacitor by shorting their legs through high resistance material. If you forget to discharge the capacitor, this may lead to a false reading and sometimes can damage your measuring device as well. After discharging, take the capacitance meter or multimeter and connect the probes.
I am familiar with the process of checking a single capacitor for a short or open circuit by charging/discharging the capacitor with a digital meter and watching the resistance values to determine the integrity of the capacitor. Is the same principal of testing used for 3-phase capacitor units.
