传统钢卷尺检定台读取钢卷尺刻度偏差的体例是野生将带读数显微镜的滑车挪动到丈量地位，经由进程肉眼将规范尺方针刻度线纹与读数显微镜镜头某一刻度线纹对齐，滑车坚持不动，而后微调手轮，使得读数显微镜上述刻度线纹与被测尺方针线纹对齐，再读取读数显微镜刻度在这一进程中的变更量。在钢卷尺逐米检定进程中，需屡次挪动小滑车地位，再反复人眼对准读数，这类丈量体例读取钢卷尺刻度偏差进程烦琐，且读数显微镜视场狭窄，读数费时又坚苦。全体效力低，检定职员任务量也大。
QT-0011钢卷尺主动读数检定台，可主动图象辨认刻度偏差，即便是差别的操纵职员也𝓡能坚持杰出的数据分歧性，同时带有5个高清产业相机，站在电脑旁便能够实现逐米5个地位的偏差丈量，切确又高效，别的还带有ཧ砝码主动加载器、数据存储和原始记实生胜利能，检定职员任务方便性大大进步。
