1. How to test a capacitor without capacitance measurement If only a simple multimeter without a function for capacitance measurement is available, then only the rough functionality of the capacitor or electrolytic capacitor (electrolytic capacitor) can be checked.
There are several ways to check a capacitor using a multimeter. Basically, however: The multimeter requires a special measuring device in order to be able to test capacitors and thus to determine the exact values of the capacitance of a capacitor.
One of the most common ways to test a capacitor is by using a multimeter. We can do this test in two different ways: 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.
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.
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.
Then, the power supply must be turned on and the time taken for the Capacitor to charge to 63.2% of the supply voltage should be measured. Next, from this Time and Resistance, the Capacitance must be measured by the formula τ = R × C and it should be compared with the value printed on the Capacitor.
