Abstract
The influence of the contacts on the precision of the quantized Hall resistance is studied in a series of high precision measurements. Deviations of the Hall resistance of up to 0.35 ppm from the expected values are observed if the resistance of one of the voltage contacts is comparable to the Hall resistance.
