Measurements • The information acquired is based on the output of the measurement device or system. There are important issues to be addressed to ensure that the output of the measurement device is a reliable indication of the true value of the measured variable
Measurement FeasibilityWe must address the following important questions:1. How can a measurement or test plan be devised sothat the measurement provides the unambiguousinformation we seek?2. How can a measurement system be used so thatthe engineer can easily interpret the measured dataand be confident in their meaning?

Learning Objectives: identify the major components of a general measurementsystem, and state the function of each.: develop an experimental test plan,: distinguish between random and systematic errors, describe and define the various error types,: define a standard and distinguish among primary,secondary, and transfer standards, and clearly delineate defined and derived dimensions in variousunit systems
