Precision resistors: a review of the techniques of measurement, advantages, disadvantages, and results
D.W. Braudaway · IEEE Transactions on Instrumentation and Measurement · 1999
The characteristics of the principal resistance measuring systems developed over the last two centuries are reviewed, Also reviewed is their application to measurement of resistance from /spl mu//spl Omega/ to M/spl Omega/. Included in the review are potentiometer systems and their adaptation to computer operation, the Wheatstone bridge, the enhanced Kelvin double-bridge and the current-comparator in both manual and computer operated forms. Methods of establishing ratio from the base 1 /spl Omega/ reference value throughout the range are discussed. Uncertainties attainable at the highest levels of precision are presented.
