Errors in Measurement
This chapter is devoted to analyzing the basic aspects of errors in instrumentation measurements. A few general definitions related to instrumentation properties are first offered. In a second part, elements contributing to measurement quality, such as precision, systematic errors, hysteresis, dead band, sensitivity and speed of response, are covered. Following are the terminology and concepts used in calibration curves. Finally, in the last part, a brief review of the accuracy of different instruments is offered. A more complete coverage of the material discussed in this chapter can be found in the handbooks on instrumentation edited by Liptak (1997) and Webster (1999).
