Abstract

A re-evaluation of the coaxial bridge system used in the traceable measurements of NPL 10 pF primary capacitance standard via the DC, QHE is discussed. Comparisons are made between the previously reported measurement uncertainties and recent measurements on the 100:1 equal power, quadrature and 10:1 coaxial bridge systems, in order to evaluate systematic errors.
