2、端的校正螺钉，使气泡向正中间位置退回一半为使竖轴竖直，再用脚螺旋使气泡居中即可此项检验与校正必须反复进行，直到满足条件为止。 （2）十字丝竖丝应垂直于横轴的检验和校正检验时用十字丝竖丝瞄准一清晰小点，使望远镜绕横轴上下转动，如果小点始终在竖丝上移动则条件满足否则需要进行校正。校正时松开四个压环螺钉（装有十字丝环的目镜用压环和四个压环螺钉与望远镜筒相连接。转动目镜筒使小点始终在十字丝竖丝上移动，校好后将压环螺钉旋紧。2、水准仪及水准尺检验：（1） 光学测微器效用正确性的检验和分划值的测定步骤：架设水准仪，将仪器视准轴瞄准水准尺，使用倾斜螺旋使水准气泡影像精密符合，在一测回内要严格保持倾斜螺旋的位
3、置不变。旋转测微器螺旋，使测微器读数略大于零，指挥扶尺者将特制分划尺上下移动，直到特制分划尺上某一分划线被楔形丝平分。然后将特制分划尺固定，并在一测回中保持此位置不变。往测旋进测微螺旋，用楔形丝分别夹准特制分划尺上两相邻分划线，读取并记录分划线编号和相应的测微器读数。返测按相反的次序，旋出测微螺旋，使楔形丝分别夹准特制分划尺上两相邻分划线，读取并记录分划线编号和相应的测微器读数。至此算作一个测回。每测完两个测回后，应略微移动分划尺或变更仪器高度，使每两个测回分别观测分划尺上不同的分划间隔。（2）、视准轴与水准管轴相互关系的检验校正：、i角检验：设水准管轴不平行于视准轴，它们之间的交角为i。当水
4、准管气泡居中时，视准轴不在水平线上而倾斜了i角，水准仪至水准尺的距离越远，由此引起的读数偏差也越大。检验时，在平坦地面的一直线上选定J1，A，B，J2四点，点间距均为20.6m， 具体检验结果如下：i角误差的检验对于精密水准仪，要求i角小于20。超出限差时，必须对其进行校正。算出i=12终点.时段DX/改正数DY/改正数DZ/改正数距离/改正数中误差/相对误差I025-I075.191B-955.5505-434.5615-93.10521053.84490.03240.0088-0.00420.0001-0.00631: 32550I67-I068.191H-74.4072-140.6239
