Precise measurement of a ratio of resistance, 6453.2 to 1, is required to calibrate 1-Ω standard resistors against the quantized Hall resistance. In this paper, a novel technique is proposed which can measure this ratio with an accuracy of 0.01 ppm by using three Hamon devices and a high-precision Wheatstone bridge. In addition, the ratio 6453.2:10000 is obtained as a by-product.
