Often multiple coils are necessary to adequately measure across the 0.5 ～ 330pF range. For capacitors > 330pF, the quality factor can be calculated by taking the inverse of the dissipation factor (see Formula 1). What is the allowable ripple current of capacitors?
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.
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.
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)?
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.
