NRC Nuclear Energy Glossary
Oil and Gas Field Glossary
Comparison and adjustment of instruments, prior to use, to known basic reference points often traceable to the National Bureau of Standards. When calibrating instruments, often one of the reference points is "zero", thereby providing the means to establish the gain (slope) and the offset (y-intercept).

A basic control to a data source from controls and displays for calibrating a device; Also, a procedure to adjust physical devices so that they provide the most accurate results possible; calibration procedures commonly result in correction factors to be downloaded from the host processor to the device; during calibration, the device is usually not available; See Also: alignment, boresighting, initialization;
