Calibration is an essential process that verifies the compliance of a measuring instrument with its design and functional specifications. By conducting calibration, we can determine the deviation value of the measuring instrument and ensure that it aligns with its specifications. As time progresses, the performance of a measuring instrument inevitably declines, and it becomes necessary to calibrate it to preserve its function and performance. The advantages of calibrating a measuring instrument include preserving its function and performance, preventing product defects, maintaining the instrument’s condition to align with its specifications, avoiding hazardous risks, and minimizing work accidents to ensure workplace safety.
