An Automated Potentiometric System For Precision Measurement Of the Quantized Hall Resistance

This paper describes the development of an automated potentiometric measurement system that is used to compare the quantized Hall resistance with that of wire-wound reference resistors having the same nominal value. Conceptual considerations, along with the major practical problems associated with this method, are presented. We then report experimental results which demonstrate that this measurement system is accurate to within a 0.007 ppm one standard deviation uncertainty.
