Abstract

The quantized Hall resistance R_H(2) is compared with various 100-kΩ AC resistance standards. The measurements were performed with an 8:1 four terminal-pair divider bridge at a frequency of 1592 Hz. The 100-kΩ resistances were previously calibrated using the PTB ohm chain starting at the DC side with the same quantum Hall resistance. The mean AC value of the quantized Hall resistance was 12906.4017 Ω with a relative standard deviation of 0.14×10^-6 after ten measurements. The total uncertainty, which is mainly determined by the AC bridge, was about 3×10^-6
