Description
The authors discuss the quantum Hall effect being used to monitor the U.S. legal representation of the ohm, or as-maintained ohm, ΩNBS. Measurements have been made on a regular basis since August 1983. Individual transfers between the quantized Hall resistance RH and the five 1-Ω resistors which comprise ΩNBS can now be made with a total one standard deviation (1σ) uncertainty of +-0.014 ppm. This uncertainty is the root-sum-square of 32 individual components
