Calibrations in Instrumentation and Measurements
Pages 14

Calibration of instruments assures that the processes are well controlled and the products meet expected speciŸcations since the measurements can dri£ away from their correct and calibratedvalues resulting in unreliable readings. For example, if the representation of process variables dri£s away from their true range, it can result in costly production downtimes, create adverse safety issues, and lead to inferior quality goods being produced. Today, in our daily lives, we are very much dependent on the correct operations of instruments, for example, when driving vehicles, but we take them for granted with the expectation that they are all functioning well giving us correct readings, which may not be the case.
