Gage Calibration: Setting the Standards and Documenting the Calibration
Gage calibration, also known as gauge calibration , is the process of verifying and adjusting the accuracy of measuring instruments or gauges. This process is important to ensure that the measurements taken by the instruments are reliable and consistent. During gage calibration , the instrument is compared against a known standard or reference, typically a more accurate instrument or a calibration standard traceable to a national or international standard. Any deviations or inaccuracies found in the instrument are then adjusted or corrected to bring it back into alignment with the standard. The calibration process typically involves the following steps: 1. Establishing a calibration interval: Determining how often the instrument needs to be calibrated based on its usage, environment, and manufacturer's recommendations. 2. Selection of calibration standards: Choosing appropriate reference standards with a higher level of accuracy than the instrument being calibrated. 3. Performing
