Let’s get into the practical method of capacitance measurements. You may encounter two cases in which you may measure the capacitor. The first case would be a solo capacitor. No matter what is the situation the first step is to discharge the capacitor fully. A capacitor is a charge storing device.
Following are the steps using which we can measure the capacitance of the capacitor using a digital multimeter. See the results on the display. The values may start from low and gradually increase. Take the highest value.
The key to measure the capacitance and dissipation factor correctly is the meter settings. The voltage settings are critical for high capacitance capacitors. For some cap meters, the applied voltage to the test component is not enough and the capacitance reads low. The frequency settings are also important.
Let’s start with our first method, the visual method. This method is the easiest and most effective way to measure the capacitance value of any given capacitor. Follow the below easy steps for an electrolytic capacitor: On the body, you will find the written capacitance value for rated maximum voltage and tolerance. It is that simple.
Models with a capacitance range of at least 100 μF are recommended. Test leads – A pair of reusable multimeter test leads with sharp, slim probes facilitates accurate capacitor testing. Lead sockets that firmly grip capacitor legs are also useful.
Therefore, Cs should be used for the meter setting to measure capacitance. A good rule of thumb to select the impedance setting is to use Cp for capacitor impedance values greater than 10kΩ and Cs for less than 10Ω. How can I accurately measure the quality factor (Q)?
