CAPAOTANCEAGCUBACY TEST
4-18. This test checks capacitance measurement accuracy
for various combinations of
test signal frequency, test signal level and cable length. The capacitance accuracy checks
are
made
by
connecting a standard capacitor to the instrument and comparing
measurement results with the calibrated values of the standard.
Accuracies for
dissipation factors near zero are also checked in this test.
Capacitance accuracy check ranges (cable length = Om)
