The specific method is: contact the two leads of the capacitor with the red and black meter pen, remember the size of the leakage current (resistance value) when the pointer swings back and stops, and then connect the positive and negative lead of the capacitor short, and then test the leakage current after adjusting the red and black meter pen.
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?
The quality factor is a measure of the extent to which a capacitor acts like a theoretically pure capacitor. It is the inverse of the dissipation factor (DF). Q is typically reported for capacitance values ≦ 330pF, DF > 330pF.
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.
