Calibration and Metrology Glossary of Terms
|Accuracy:||Conformity to fact, exactness.|
|Calibration:||To check, adjust, or determine by comparison with a standard, the readings from a measurement device.|
|International System of Units, SI:||
This is a coherent system of units defined through international consensus.

|Measurement:||The act of measuring or the process of being measured|
|Metrology:||The science of weights and measures. A system of weights and measures.|
The state or quality of being precise; exactness.
|Primary Laboratories:||These are metrology laboratories, like National Test Equipment, capable of realizing and maintaining an SI unit through a primary standard, and of carrying out calibrations with respect to the primary standard.|
|Primary Standard:||This is a standard that is designated or widely acknowledged as having the highest metrological qualities in a specified field.|
|Resolution:||The fineness of detail that can be distinguished (as in a moving coil meter face, for example).|
|Tolerance:||The allowable variation from a standard.|
|Traceability:||To have origins; be traceable - the 'pedigree' of a calibration.|
Uncertainty:||The estimated amount by which an observed or calculated value may differ from the true value.|
