Definition
The process of comparing indications from a measuring instrument with an appropriate reference to determine measurement error and support confirmation of fitness for use.
Human Explanation
Calibration checks how an instrument’s indications relate to a known reference.
Why it Matters
Reliable decisions depend on measurements whose uncertainty and error are understood.
Conceptual Boundary
Calibration is not repair or adjustment, although its results may show that adjustment is required.
Practical Perspective
Calibration should follow a justified schedule, use traceable references where required and produce controlled records.
