How the needle behaves determines whether or not the capacitor is good. If the needle initially shows a low resistance value then gradually moves towards infinity, the capacitor is good. If the needle shows a low resistance value and doesn’t move, the capacitor has been shorted out. You’ll need to replace it.
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.
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.
It is reading as if there is an open circuit across the capacitor. A normal capacitor would have a resistance reading up somewhere in between these 2 extremes, say, anywhere in the tens of thousands or hundreds of thousands of ohms. But not 0Ω or several MΩ. This is a simple but effective method for finding out if a capacitor is defective or not.
A capacitance meter is an electronics device that measure the value of capacitance for any given capacitor (both electrolytic and ceramic). Most multimeter also have capacitance measuring feature. You can use such multimeter as well for this method. Follow the following steps: First do the visual inspection. If the given capacitor pass that test.
