Abstract
The paper introduces the cryogenic current comparator (CCC) resistance ratio bridge being built at DFM, which is designed to relate the value of quantized Hall resistance R/sub H/(i) to room temperature resistance standards. The CCC is an overlapping tube type with copper wire. A double constant current source is used to supply for the CCC resistance ratio bridge.<>
