AC/DC transfer standards calibration in Central Military Calibration Laboratory

The article discusses the method used at the Central Military Calibration Laboratory to calibrate Fluke 5790 AC/DC transfer standard with the reference transfer standard Fluke 792A. It presents the measurement equation and the uncertainty budget. The contribution of uncertainty components in the measurement uncertainty has been presented. The metrological traceability has been evaluated by comparing calibration results with the results in the last Fluke certificate of calibration.
