Short answer: No. A capacitance measurement will only give you part of the picture. You also need to measure the ESR, especially for electrolytic capacitors. You could have an electrolytic capacitor that measures exactly what its rated capacitance suggests, but the cap will not work at all in the circuit because its ESR is too high. Functional?
The electrostatic capacitance of ceramic capacitors is generally measured using an LCR meter. 2. Measurement principle The typical measurement system of LCR meters is the "automatic balancing bridge method," such as shown in the figure below. The measurement principle is as follows.
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.
The second method describes a measurement that is suitable for measuring on larger capacities and can also determine the internal series resistance (ESR). This method is thus mainly suitable for measuring on electrolytic capacitors. Figure 8 shows the mathematical model with the associated vector diagram in figure 9.
Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it's capacitance measurement is +- 20% of it's declared value without doing the ohm/voltage test? Are these test overkill after the capacitance value has been verified?
