The precision length calibration process is very much like any length measurement process, but taken to a significantly higher level. Both processes are composed of the same elements, including the following five key parts of any measurement/calibration process:
The Standard: This can be any certified physical dimensional standard used for setting a zero or starting point. Any standard employed in a measurement/calibration process should be recently certified, clean, free of damage/corrosion, temperature stable, and appropriate for that particular measurement process.
