Measurement Systems Characteristics – Part I

In Lesson 3, we start with the concept of stability of the measurement system.  Just as we should be concerned with stability of production processes, we need to monitor measurement systems to detect significant changes.  We define the characteristics of an ideal measurement system.  In order to even assess measurement systems, we must have adequate discrimination, and this is the first characteristic discussed.  We then define and describe accuracy and precision as they relate to measurement systems.
