【Abstract】 For the problems of lack calibration and superfluous calibration caused by traditional metrology and assurance ways,a condition-based metrology method for automatic test systems was proposed.Firstly,the system of condition-based metrology was established.Then,according to calibration requirements of automatic test systems,the traceability design was presented.After historical calibration data were analyzed,calibration interval optimization models were proposed.Furthermore,the measurement process control was also used during two calibration’s intervals to monitor quality values.Experiments show that the condition-based metrology improves the metrological efficiency of automatic test systems.更多还原
