Traceability of the 10-kΩ standard at IEN

The traditional scaling method used at the Istituto Elettrotecnico Nazionale (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. For the three methods, the measurement results and the uncertainty budgets are reported. The agreement is better than 1/spl times/10/sup -7/.
