标准、校准及跟踪 所谓的校准仪器,其内容之一就是用它去测量“标准”件,而这些“标准”件的特性或参数是已知的。通过这种测量调整仪器,使其测量的结果与“标准”件的特性或参数相一致。因此,对标准件的质量要求非常高,因为其后由该仪器所进行的测量都是与校准结果相比较而言的。通常,仪器的校准是逐级传递的,例如A级标准用来校准标准实验室中的B级仪器,B级用来校准在工厂中使用的C级仪器,C级用来校准最终的产品D,校准D的实际上是A,校准的路径是A→B→C→ Standardizing, calibrating and tracking so-called calibration instruments, one of its contents uses it to measure “standard” pieces whose characteristics or parameters are known. Adjust the instrument with this measurement to make the result of the measurement consistent with the characteristics or parameters of the “standard” piece. Therefore, the quality requirements of the standard parts are very high, since the measurements made by the instrument thereafter are compared with the calibration results. Typically, the calibration of the instrument is carried out step by step, for example, Class A standard is used to calibrate Class B instruments in a standard laboratory, Class B is used to calibrate Class C instruments used in a factory and Class C is used to calibrate the final product D , Calibration D is actually A, calibration path is A → B → C →
