执行校准的一个关键原因是评估设备是否超出公差。常见的校准测试场景通过测量过程将设备参数与测量标准的参数进行比较。如果设备参数与测量标准之间的差值大于指定的公差，则认为该设备超出了公差。然而，测量过程中的错误会带来不正确评估的可能性。不正确的评估可能会导致设备错误地声明为不允许(错误-接受)或错误地声明为超出允许范围(错误-拒绝)。
One key reason for performing a calibration is to assess a device as either inor out-of-tolerance. Common calibration test scenarios compare a device parameter against that of a measurement standard by way of a measurement process. If the difference between the device parameter and the measurement standard is greater than the specified tolerance, the device is deemed out-of-tolerance. However, errors in the measurement process bring about the possibility of an incorrect assessment. An incorrect assessment may result in devices incorrectly declared as in-tolerance (false-accept) or incorrectly declared as out-of-tolerance (false-reject).
