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.
To test a capacitor with a multimeter, you need to follow these steps: Disconnect the capacitor from the circuit. Before testing a capacitor, you need to make sure that it is not connected to any power source or other components in the circuit. This will prevent any damage to the multimeter or the capacitor. Discharge the capacitor.
To test a capacitor with a voltmeter, 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.
In summary, the best solution to test a capacitor without desoldering it actually for the circuit board is either using an ESR meter or smart tweezers. Both work the same and are fine to use. But the ESR meter is preferred for through-hole capacitors, and the latter one is preferred to test SMD capacitors.
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.
You may also see the Greek letter mu (µ), which looks like a lowercase “u” with a tail in front of it. (Because the farad is a large unit, most capacitors measure capacitance in microfarads; a microfarad is a millionth of a farad.) Set your multimeter to its capacitance setting.
