Characterizing & Disciplining Electrical Calibrator Instrumentation to Improve Test Accuracies & Measurement Uncertainties (154.06 KB)

This paper examines a solution to the problem of insufficient accuracy of calibration sources used for dc & low frequency ac electrical voltage, resistance, and current calibration when the instruments being tested have an accuracy which approaches that of the calibrator. The solution lies in techniques of using higher accuracy precision measurement devices to characterize the calibrator and thereby improve the measurement uncertainties obtained in these tests.
