The differences in repeatability measurements between one operator than another will affect the accuracy, precision and hence the uncertainty of the same device measurements. To try to avoid or reduce the variation in repeatability measurements between each operator, a special automated translation stage was designed to improve the accuracy of measurements at defined positions. This automated stage was applied to measure the irradiance levels of two phototherapy luminaires as an example of an exposing cabinet. The standard regulations recommend that the irradiance level of any exposed area must be collected at specified positions. The results of using an automated stage show that there are personal errors affecting the manual repeatability measurements. Using the automated stage in collecting data, the standard deviation of repeatability decreased significantly by 87.5% for LED luminaire and 43.3% for the fluorescent lamps luminaire. Besides, the automated stage saved the time and energy of the operator in the most accurate way.

开发自动过渡阶段作为提高测量精度质量的一种方式

一个操作员与另一个操作员之间的可重复性测量差异将影响同一设备测量的准确度、精确度以及不确定度。为了尽量避免或减少每个操作员之间重复性测量的差异，设计了一个特殊的自动平移台来提高定义位置测量的准确性。该自动化平台用于测量两个光疗灯具的辐照度水平，作为曝光柜的示例。标准规定建议必须在指定位置收集任何暴露区域的辐照度水平。使用自动化平台的结果表明存在影响手动重复性测量的个人错误。使用自动化阶段收集数据，LED 灯具的重复性标准偏差显着降低了 87.5%，荧光灯灯具的重复性标准偏差显着降低了 43.3%。此外，自动化平台以最准确的方式节省了操作员的时间和精力。
