Answer:
Calibration
Explanation:
The calibration of any measuring instrument is necessary to measure the quantity in terms of standard unit. It is the process of framing the scale of the instrument by applying some standardized signals. Calibration is a premeasurement process, generally carried out by manufacturers.
It is carried out by making adjustments such that the read out device produces zero output for zero measured input. Similarly, it should display an output equivalent to the known measured input near the full scale input value.
The accuracy of the instrument depends upon the calibration. Con stant use of instruments affect their accuracy. If the accuracy is to be maintained, the instruments must be checked and recalibrated if neces sary. The schedule of such calibration depends upon the severity of use, environmental conditions, accuracy of measurement required etc. As far as possible calibration should be performed under environmental conditions which are vary close to the conditions under which actual measurements are carried out. If the output of a measuring system is linear and repeatable, it can be easily calibrated
