摘要：
The ability to accurately measure a physical quantity changes with a variety of factors. As such, calibration quantifies measurement uncertainty by comparing user measurements to a known standard so as to verify that the measurement device is operating within stated specifications. If the device's measurements exceed the published uncertainty, then the product's measurement circuitry is adjusted until there is agreement with the published specification.
