The three-terminal test port of the instrument uses the standard rubber jack, therefore the
inexpensive rubber plug- alligator clip can be used as the test line. It is very convenient to apply
the extended test, but the drawback is low testing accuracy.
To improve the accuracy of the test line when using the extension line, the LCR is also equipped
with the five-terminal test notch for dedicated test fixture. It renders possible the complete
four-terminal measurement of the extension line to ensure the high testing accuracy.
