As you know, a capacitor has two terminals, and we measure capacitors in terms of capacitance. Capacitance (C) is the ability of a capacitor to store energy. The unit of capacitance is Farad. Let's see some fundamental mathematics of capacitance. You can see that capacitance is the ratio of total charge and the voltage applied across the capacitor.
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.
Capacitance C, dissipation factor D, and equivalent series resistance ESR are the parameters usually measured. Capacitance is the measure of the quantity of electrical charge that can be held (stored) between the two electrodes. Dissipation factor, also known as loss tangent, serves to indicate capacitor quality.
When measuring other capacitors the frequency must be chosen lower than desired what means that only the capacitance can be measured. Two examples are given: The first one is for measuring only the capacitance, and the second one is for measuring the capacity as well as the ESR.
