Abstract
A method has been developed to relate the mean value of the IEN primary group of 1-Ω standard resistors to the i =2 quantum level of the Hall resistance. It is based on an automated potentiometric system, a 36×360 Ω Hamon network, and a commercial Kusters current comparator bridge. A description of the equipment and of the measurement technique is given together with a detailed uncertainty budget. The typical fractional global uncertainty of the measurement of one standard deviation level is 5×10-8
