Artifact Calibration and Its Use in Calibrating 8.5-Digit DMMs (1.1 MB)

Verifying that an 8.5-digit digital multimeter’s (DMM’s) measurement performance is within its specification is not a trivial task. In dc and low frequency ac electrical metrology, the specifications are similar for both the DMM (measurement device) and the calibrator (source) used to verify it. Specified maximum measurement errors are typically on the order of 5 to 50 parts per million over various functions and ranges. When using an electrical calibrator as a source to calibrate/verify a precision DMM, the calibrator’s performance must be at its best level with minimum uncertainties.

This paper examines how the Artifact Calibration capabilities of the Fluke Calibration 5700 Series of Precision Multifunction Calibrators can optimize the uncertainties for calibrating 8.5-digit DMMs.
