Abstract :
The traditional scaling method used at the Istituto Elettrotecnico Nazionale (IEN) for the calibration of the 10-kΩ 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 1×10-7
