  • Abstract
    A system based on a cryogenic current comparator is used to measure the quantized Hall resistance RH in terms of Omega 69-BI, the Bureau International des Poids et Mesures (BIPM) representation of the ohm, with an uncertainty of 1.5*10-8. This measurement system and the former potentiometric one are in good agreement within their combined uncertainties (5.1*10-8).
