专用测试系统计量校准问题讨论

Discussion on Calibration of Test Systems

针对计量行业的难点问题之一"专用测试仪器系统"的计量校准问题进行了系统性讨论。首先,从其定义出发,结合其技术目标的特殊性特点,分析了专用测试系统的技术特征。其次,针对其校准中存在的歧义,如综合校准的含义、系统校准的含义等进行了辨析讨论,对于现场校准的三种基本模式特征进行了系统性区分和讨论。最后,针对其计量校准规范的制订难度,提出了制订单参量通用校准规范的方式予以组合使用解决方案,以及具体实现综合性校准和系统性校准的具体步骤。

A discussion on the problems of calibration of test systems is presented. First,beginning from the definition of the test system and combining the specialties of the target of test systems,the features of test systems is analyzed. Then,aiming at the ambiguity on the calibration of test systems,such as synthetic calibration and system calibration,some definitions are discussed in detail. The characteristics of three basic calibration modes are identified and analyzed. Finally,to the difficulties on drawing calibration specifications of test systems,one scheme is taken out,which is the combination of different single parameter calibration specifications. And both the steps and process for synthetic calibration or system calibration are presented.
