Abstract

Scaling from the quantum Hall resistance to 100 Ω standard resistors used by the NIST-4 Watt Balance involves multiple resistance standards and bridges to provide the lowest possible uncertainty. Described here is the infrastructure and procedures developed to support these measurements at better than 20 x 10^-9 standard uncertainty levels.
