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.
