701A型孔径测量仪对震动很敏感,微小的震动都会引起干涉带条纹的抖动,给读数造成困难。采取下述简便方法,可使它的工作条件得到明显改善: 1.去掉底脚螺钉上的垫脚1,使底脚螺钉的圆弧面2直接与减震橡皮垫接触(参看下图),或按需要重新制作接触面积较小的底脚螺钉(以仪器安放稳妥为前提)。同时适当增大减震橡皮垫的面积,其直径不小于100毫米。 2.用四个小千斤顶在桌子底部适当位置将桌子顶离地面,离地间隙以一张薄纸能顺利通过为
701A aperture gauge is very sensitive to vibration, small vibration will cause interference with stripe jitter, to make reading difficult. The following simple method can be used to improve the working conditions: 1. Remove the foot 1 on the foot screw, make the arc surface 2 of the foot screw directly contact with the shock absorber rubber cushion (see below), or According to the need to re-create a smaller contact area of the foot screws (the instrument placed on the premise of security). At the same time, the area of shock absorbing rubber pad should be increased appropriately, and its diameter should not be less than 100mm. 2 with four small jack at the bottom of the table at the right place the table top off the ground, ground clearance to a thin paper can be passed
