Measuring Systems
摘要
The International Vocabulary of Metrology (VIM) defines a measuring system as a “Set of one or more measuring instruments and often other devices, including any reagent and supply, assembled and adapted to give information used to generate measured quantity values within specified intervals for quantities of specified kinds. A measuring system may consist of only one measuring instrument.” [VIM—3.2] In this chapter, we will analyze some basic concepts and the main metrological characteristics of measurement systems, such as reading resolution, sensitivity, stability, drift, measurement errors, accuracy, precision, repeatability, and reproducibility.
