内容記述 | In this report, the digital level is referred to a level that aims at bar-code staff and reads the height of that collimation axis automatically. We go back to the measurement principle of a digital level, and examine the reading accuracy. Hereafter, as long as there is no notice in particular, we treat the digital level NA 3000 and staff GPCL3 manufactured by Leica. When using a digital level, we most worry about whether a level recognizes a sta scale correctly or not. Moreover, we also want to know the measurement accuracy. In this case, the quantity which must be grasped at least is the minimum resolution of a reading, and proportional relation between a reading and a staff scale. The results of our examination mostly confirm the characteristic of specifications given by Leica. The resolution of measured value was decided as 20 micrometers or less at the maximum. Furthermore, the error of linearity was presumed to be about 20 micrometers over 3m staff. Since the stability and setting accuracy of horizontal axis are the basic performance of a level, we made those examinations of Leica digital level in the second half part of the report. | |||||
