3 Measurement Tutorial
The values of capacitance and loss resistance measured with the multimeter may
differ from the values measured using an LCR meter. This is to be expected, since
this is essentially a DC measurement method, while LCR measurement uses
applied frequencies anywhere from 100 Hz to 100 kHz. In most cases, neither
method measures the capacitor at its exact frequency of application.
For the best accuracy, take a zero null measurement with open probes, to null out
the test lead capacitance, before connecting the probes across the capacitor to be
measured.
