Calibration

Calibration or instrument calibration is one of the primary processes used to maintain instrument accuracy. Is the operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and, in a second step, uses this information to … Leggi tuttoCalibration
