Research of transfer quantum hall resistance with direct current comparator bridge instrument

The problems of transfer Quantum Hall resistance to 1 Omega resistance standard with direct current comparator bridge (DCC) are introduced. Some effective technique ways are suggested by analyzing the possible causations of the measurement results' fluctuation. The comparing experiments between DCC and cryogenic current comparator bridge (CCC) have been performed with analyzing the uncertainty of measurement results. The transfer uncertainty from Quantum Hall resistance to 1 Omega standard with DCC is 3times10-8 (k=1), which is enough accurate in practical resistance standard calibration of metrology.
