Abstract :
Commercial quantum Hall resistance standard has been put into operation at the CMI. Small, but systematic discrepancy between results obtained at 2nd and 4th QHE plateaux was observed and its possible origin will be discussed. Unpredictable drift of the built-in 100Omega transfer standard will also be dealt with
