激光功率计的量值标定是由计量部门进行的,定标时由标准功率计的读数标定待测功率计的读数。但是由于运输途中的震动、使用中的损坏或其它事故,很容易造成定标数值的变化,用户再次送到计量部门进行定标,不但耽误时间,而且还会造成不必要的经济损失。本 The calibration of the laser power meter is carried out by the measurement department. The calibration of the power meter is calibrated by the reading of the standard power meter. However, due to the vibration in transit, the use of the damage or other accidents, it is easy to cause the calibration value changes, the user sent again to the measurement department for calibration, not only the delay time, but also cause unnecessary economic losses. this
