It may be the beginning of knowledge, but you are scarcely in your thought advanced to the stage of a science.” Lord Kelvin  You don’t know anything about anything unless you can measure it.

Davis  Keeping America’s Navy #1 in the World  7     Definitions WARFARE CENTERS CORONA  Metrology: The Science of Measurement  Calibration: VIM: Set of operations that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realized by standards. Navy: Calibration is the comparison of a measurement system or device of unverified accuracy, to a measurement system or device of known or greater accuracy, to detect and correct any variation from
required performance specifications.

WARFARE CENTERS CORONA  • Ensure the readiness of test equipment to perform accurate measurements and provide valid data • Limit the number of erroneous test decisions • Maintain overall measurement integrity and traceability Keeping America’s Navy #1 in the World  10     Why Calibrate? – Data Integrity WARFARE CENTERS CORONA  • How do we know the data is good? – – – –  Accurate? Precise? Stable? Can you trust the person collecting the data? Can you trust the measurement instrument?
