At this point the dial gauge extension is positioned exactly at a rightAngle to the front face of the pinion head.
达到此点时,百分表加长杆正好与小齿轮头部的前面成直角。
2
Fit the dial gauge holder with the dial gauge so that a rightAngle is produced between the dial gauge axis and the measuring lever.
安装好百分表与其支架,从而使百分表轴线与测量杆之间呈直角。
3
