CHOICE OF THE MEAUREMENT POINTS FOR A CALIBRATION IN A RANGE

Umberto Pogliano

Abstract

Calibration of instruments like modern programmable instruments is generally made in specific points within each range, even if the desired result is the general calibration of the instruments. This paper is considering the problem of how many points are needed for a correct calibration of a range, and, by means of a statistical approach, the method propose evaluates a confidence interval where the difference between the measured and the calibrated can be confined with an assigned probability.
