Measurement Procedure and Examples
Measurement Contacts
7-
Contact Resistance
Contact resistance between the contacting terminals and the DUT causes
measurement error when measuring large values of capacitance, especially in
D (dissipation factor) measurements.
When measuring large capacitance values, the four-terminal measurement
contacts have the advantage of less measurement error as compared to the
two-terminal method. Select a test fixture which can hold the DUT tightly to
stabilize the connection.
