Recent determinations of R/sub H/ in terms of Omega /sub 69-BI

A system based on a cryogenic current comparator is used to measure the quantized Hall resistance R/sub H/ in terms of Omega /sub 69-BI/, the Bureau International des Poids et Mesures (BIPM) representation of the ohm, with an uncertainty of 1.5*10/sup -8/. This measurement system and the former pote...

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