Abstract :
A project funded by the European Commission which started in 1998 has been completed. The aim of this project was to establish a measurement system that allows the calibration of standard capacitors in terms of R/sub K90/. The whole system comprises quantum Hall samples, an automated modular bridge system, and devices to calibrate and characterize the set-up. The uncertainty for the calibration of a 10-pF capacitor is about one part in 10^7.
