Abstract :
The traditional scaling method used at IEN for the calibration of the 10 k/spl Omega/ standard is compared with more straightforward techniques, one based on the linearity of a DVM and the other on a commercial current comparator bridge. The results of the three methods agree to better than 1/spl middot/10/sup -7/.
