RD-22 Dytronic Primary Transfer Ultra Stable Standard

RD-22 Dytronic Primary Transfer Ultra Stable Standard

The RD-22 Ultra Stable Primary Transfer Standard represents the state-of-the art technology in a commercially available AC transfer reference. The Ultra Stable RD-22 is a variant of the RD-ě2 Primary Transfer Standard that has been optimized for 120/240V @ 5A operation to provide optimum stability. In a stable test environment, repeatability for a 10-second test of +- 0.6 mikroWh/VAh is attained at 120v and 240 V at 5A inputs with a 95% confidence interval. A typical experimental 2 repeatability of less than +- 0.25 mikroWh/VAh is achieved. In a stable test environment, a reproducibility of +-2mikroWh/VAh over a five-day interval is attained at 120V and 240V at 5A inputs with 95% conficence interval.
