calibration

1. Quality: (1) Determination whether or not the characteristics of an assembly, component, or material are within specifications. (2) Matching or reconciliation of a measuring device of unverified accuracy with another device that is known (verified) to be of standard or superior accuracy. Any difference found between their accuracies is used to adjust the first (unverified) device.

2. Plans: Comparison of a mathematical or theoretical model’s predictions with the actual data, and the adjustment of its underlying assumptions or equations to achieve a better fit with the reality.
