Abstract :
In this paper we describe the setup we have developed for intercomparison of resistors with the quantum Hall effect using a 8 1/2 digit digital voltmeter. A unique feature of the system is its simplicity in setup and operation, whereas at the same time an estimated accuracy of better than 1 part in 10/sup 7/ is obtained.
