Using a multimeter to test a capacitor is straightforward: Set your multimeter to the capacitance (usually labeled as “C”) mode. Discharge the capacitor by short-circuiting its terminals with a resistor or insulated screwdriver. Connect the multimeter probes to the capacitor terminals, ensuring the correct polarity.
There is left one choice we can use to test a capacitor, and that is by measuring its equivalent series resistance (ESR). You know, when the capacitor is in use for a long time. Its capacitance value tends to decrease because the capacitor dries out with time, but its internal resistance value increases.
To test a capacitor with resistance, you need to follow these steps: Disconnect the capacitor from the circuit. As before, you need to make sure that the capacitor is not connected to any power source or other components in the circuit. Discharge the capacitor.
Turn on the ESR meter, and short its leads until you get a 0 reading on its screen. If the screen is already showing a 0 reading, then there is no need to short the leads. Place the red lead of the ESR meter into a positive and black lead to the negative terminal of the capacitor under test. Note the readings on the ESR meter.
Check the capacitor’s voltage rating. This information should be printed on the outside of the capacitor as well. Look for a number followed by a capital “V,” the symbol for “volt.” Charge the capacitor with a known voltage less than, but close to, its rated voltage.
You just cannot test a bad capacitor inside or outside a circuit board by measuring its capacitance value with a capacitor meter or a multimeter. Because in such a situation mentioned devices lead you into false reading, and you may not be able to actually tell if the capacitor you tested was actually a bad or right one. Why?
