ABSTRACT

The performance of a measurement system is investigated in this chapter. Calibration methods are presented that assure recorded values are accurate indicators of the variables sensed. Both the static and the dynamic response characteristics of linear measurement systems are examined. First-order and second-order systems are considered in detail, including how their output can lag in time with changes in the experimental environment. With this information, approaches to data acquisition and signal processing, which are the subjects of subsequent chapters, then can be considered.
