Abstract
A capacitance scaling system from 10 nF to 100 mF [1], [2] has been implemented at the National Institute of Standards and Technology (NIST). Standard four-terminal-pair (4TP) capacitors are characterized using a capacitance scaling calibration procedure introduced in [3]. This system operates over frequencies from 100 Hz to 100 kHz and depends upon the accurate characterization of a 1 nF capacitor as well as 10:1 scaling fixture and LCR meter readings. The scaling fixture consists of an inductive voltage divider (IVD) and an electronic interface. This paper presents an uncertainty analysis of the scaling system and verifies its performance. A 10 nF capacitor was measured with a combined standard uncertainty of 5 parts in 106 at 1 kHz and 7 parts in 106 at 10 kHz.Citation
