ME6504 – METROLOGY AND MEASUREMENTS
Measurement is the act, or the result, of a quantitative comparison between a predetermined standard and an unknown magnitude.
It represents the highest possible value that can be measured by an instrument.
It is defined as the ratio of a change in scale reading to the corresponding change in pointer deflection. It actually denotes the smallest change in the measured variable to which an instrument responds.
True or actual value
It is the actual magnitude of a signal input to a measuring system which can only be approached and never evaluated.
It is defined as the closeness with which the reading approaches an accepted standard value or true value.
It is the degree of reproducibility among several independent measurements of the same true value under specified conditions. It is usually expressed in terms of deviation in measurement.
