Instrumentation calibration mainly do what?

Instrumentation calibration is simply the process of calibrating, aligning, and tuning instruments; it is defined as the process of linking the response of an instrument to its starting signal or to the true value measured by other methods. \x0d\ Under specified conditions, a set of operations to determine the relationship between the quantitative value indicated by a measuring instrument or measuring system, or represented by a physical gauge or reference material, and the corresponding quantitative value reproduced by a standard. Its purpose is to determine the indicated value of a measuring device by comparison with a standard. \x0d\ Calibration should meet the following basic requirements:\x0d\ (1) Environmental conditions If calibration is carried out in the calibration (calibration) room, the environmental conditions should meet the temperature, humidity and other provisions required by the laboratory. Calibration if carried out in the field, the environmental conditions to be able to meet the conditions of the instrument field use shall prevail. \x0d\(2) The instrument as a standard instrument for calibration of its error limit should be calibrated meter error limit of 1/3 ~ 1/10. \x0d\(3) Personnel calibration is different from the calibration, but the calibration of the personnel should be effectively assessed and obtain the appropriate certificate of competency, only the licensed personnel can issue calibration certificates and calibration reports, and only this kind of certificates and reports are considered to be valid
