When a meter measures capacitance, it sends a small test current through the capacitor. The multimeter reads this test current to determine the farads of the capacitor. In order to accurately measure this test current, the capacitor needs to be discharged. How to measure capacitance using a multimeter?
Another way to measure the capacitance is to include the unknown capacitor in a resonance circuit. The accuracy is directly dependent on the used reference inductor. Inductors with a small tolerance are rare and expensive. Fig. 11: Resonance method measuring arrangement for capacitors.
Recall that capacitance refers to a system that stores an electric charge. Recall that farads is the unit of measurement for a capacitor. The image below shows a run capacitor used in HVAC systems. Let’s learn how to set your meter to measure capacitance. Capacitance measurement plays a major role in setting up a device.
2. Capacitance Calibration The precision measurement of capacitors for the purpose of calibration is generally based on a national primary standard of high accuracy, secondary/working Standards derived from it, and a capacitance- (or LCR-) meter used for the measurement (i.e. calibration) of the devices under test (DUT).
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.
To measure the internal resistance accurate the channel 2 probe must be placed as close as possible at the capacitor. The resistor Rs must have approximately the same value as the impedance of the capacitor. De first method describes the measurement of small capacitors whereof the series resistance is negligible. Fig. 5: Mathematical model.
