Abstract :
Based on a dual Josephson voltage standard, a measuring system has been set up for highly precise determinations of resistance ratios. It is demonstrated that, by means of this system, 10-k/spl Omega/ and 100-/spl Omega/ standard resistors can be linked to a 12.9-k/spl Omega/ quantised Hall resistance with expanded uncertainties (k=2) of 5 parts in 10/sup 9/ and 20 parts in 10/sup 9/, respectively.
