Application of Automation in Calibration of Multimeter using Precision Calibrator

74-77 In computer age, there is an important contribution of automation in improving the error free precision calibration and to save the time. Automatic measurement is normally done using computer in high precision system and calibration. In the present paper, we discuss in detail about the automatic process and as a case study the precision calibration of digital multi meter by high precision calibrator traceable to ‘‘National Standard’’. The commercial software MET/CAL was used in the automation. We also discuss the process of the validation of this software prior to its use. The uncertainty evaluation reported in this paper is as per the ISO ‘‘GUM’’ document
