  • Abstract
    The BIPM has an ongoing project to establish a Thompson Lampard calculable capacitor for use in the determination of the von Klitzing constant, RK. This paper describes key parts of the measurement chain used to provide the link between the dc quantum Hall effect and the calculable capacitor. The bridge used to calibrate a conventional 1 pF standard against a known 0.4 pF capacitance change is presented. The target relative uncertainty for the overall measurement is 1 part in 108.
