Siborg System's LCR-Reader-MPA, an all-in-one multimeter. There are three main ways of measuring capacitance: DC charge/discharge, AC response and bridge methods. The first method is only applicable to RC while the latter two to LCR measurements.
The novel results in the field of measurements of very small capacitance changes are presented. The operating principles like double differential principle, RC phase delay, charging and discharging, oscillator, capacitance to phase angle conversion used for measuring very small capacitance changes are discussed.
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.
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.
The AC response method to measure capacitance is done by passing a known high-frequency alternating current through the device and recording the resulting voltage across it. From the ratio of these the magnitude of the impedance is calculated.
Application Note MPA-CB1 Rev. There are three main ways of measuring capacitance: DC charge/discharge, AC response and bridge methods. The first method is only applicable to RC while the latter two to LCR measurements.
If I have two capacitors and measure their difference, should I measure them one by one. And calculate their difference. Or I should measure a differential capacitance directly.
