Abstract :
A Cryogenic Current Comparator (CCC) Bridge for the measurement of the quantum Hall resistance and standard resistors from 1 /spl Omega/ to 10 k/spl Omega/ was built for its use at the National Center of Metrology (CENAM) in Mexico. Construction details and operating principles of the system are described.
