| Outline of Final Research Achievements |
To establish the voltage standard system based entirely on the fundamental physical constant, quantized Hall resistance (QHR) voltage divider and its evaluation system has been researched. We developed the evaluation system by using a reference voltage divider. Measurement uncertainty of QHR voltage divider of 2:1 ratio was estimated to be in the order of 0.1×10~(-6).
