Resistance calibrators for verification of instruments destined for industrial applications

Nowadays, there are some problems corresponding with specifics of industrial instrumentation metrological support, i.e., compatibility ranges of resistance reproducibility in existing calibrators and the measurement range of industrial instrumentation, disability of controlling metrological characteristics in operation mode etc. To solve such problems, the use of active resistance simulators is possible. In the paper, there is presented the proper structure of an industrial resistance calibrator together with the calibrator error analysis.
