Am. Jeffery et al., NIST COMPARISON OF THE QUANTIZED HALL RESISTANCE AND THE REALIZATION OF THE SI OHM THROUGH THE CALCULABLE CAPACITOR, IEEE transactions on instrumentation and measurement, 46(2), 1997, pp. 264-268
The latest NIST result from the comparison of the quantized Hall resis
tance (QHR) with the realization of the SI ohm obtained from the NIST
calculable capacitor is reported, A small difference between the 1988
result and the present result has led to a re-evaluation of the source
s and magnitudes of possible systematic errors.
