Abstract :
A potentiometric measurement system used to compare the quantised Hall resistance with a nominally equal standard resistor and making use of Zener current and compensation voltage sources was studied, to detect the noise limits and optimise the measurement strategy. The Allan variance was used to evaluate the time correlation of repeated measurements.
