Abstract :
Several variants of resistive transfer standard (RTS) for link between quantum Hall resistance (QHR), 12.9 k/spl Omega/ or 6.45 k/spl Omega/, and decimal resistance, 10 k/spl Omega/, are developed and investigated. Relative uncertainty of transition does not exceed (1-3)/spl times/10/sup -8/ under. The main features of the standard are the usage of the minimal number of equal resistors, small (of order 1-20 ppm) deviation of actual transfer coefficient value from nominal value, self-calibration, and simplicity of use.
