Additionally, the qualification of the unit does not meet the calibration of the experimental conditions, or not in accordance with the relevant national calibration regulations "calibration" can not be called calibration, can only be called "calibration", and does not have the qualification of the unit calibration Even under the experimental conditions in line with the verification work "verification" can not be called verification, can only be called "calibration".
