Abstract :
A cryogenic-current-comparator-based resistance measurement system in use at the National Research Council of Canada to maintain a reference of resistance is described. Results of maintenance activities since 1990 and results of comparisons of the ratio equivalence of steps two, three, four, and six at a precision of a few parts in 108 are presented
