在距离测量仪2.5米处的墙上寻找激光束的投射点,
并在该点的中心打上记号 (墙 A 上的记号为点 I
B 上的记号为点 II
把测量仪旋转 180 度后,再把仪器移动到 5 米远的位
置上。让仪器找平。
调整测量仪的高度 (借助三脚架,必要时得使用垫
块),让激光束的中心点,准确地落在墙 B 的点 II
上。
在墙 A 上寻找激光束的中心点并打上记号,此记号
便是点 III (点 III 应该为在点 I 的正上方或正下
方)
墙A上I 和点III 之间的距离d是测量仪在水平方
向的实际偏差值。
您可以使用以下的公式计算最大的许可偏差 d
max
:
d
max
= 两倍的墙壁间距 x 0.3 毫米 /
范例:如果墙壁的间距为 5 米,那麽最大的许可偏差
d
max
=2x5x 0.3 / = 3 毫米。所以记号之
间的距离,不可以超过 3 毫米。
检查垂直方向的激光束的找平精度
针对这项检验,您必须寻找一处有门孔而且地板坚实
的场地。此外,门孔的前后两侧至少要有 2.5 米的空
间。
把测量仪放置在距离门孔 2,5 米处的坚实、平坦的
地面上 (不可以使用三脚架)。让测量仪在交叉测
量的功能上找平,并且把激光束朝向门孔。
找出投射在门孔地板上的垂直激光束的中心点,并
在该中心点打上记号 (点 I。在门孔的另一侧约
5 米远处再做一个记号 (点 II,在门孔的上缘做
第三个记号 (点 III)。
把测量仪移动到门孔的另一侧,并将它放置在点 II
的后面。让仪器找平,并且调整好激光束,垂直激
光束的中心必须穿过点 I 和点 II
投射在门孔上缘的激光束的中心点和点 III 之间的距
d,便是测量仪在垂直方向的实际偏差。
测量门孔的高度。
您可以使用以下的公式计算最大的许可偏差 d
max
:
d
max
= 两倍的门孔高度 x 0.3 毫米 /
范例:如果门孔的高度为 2 米,那麽最大的许可偏差
d
max
=2 x 2米x 0.3 毫米 / = 1.2 毫米。所以记号
之间的距离,不可以超过 1.2 毫米。
有关操作方式的指点
记号一定要打在激光束的中心位置。 激光束的宽度
会随著距离的远近而改变。
使用找准片工作
使用找准片 12 可以帮助仪器对准参考线段,也可以
让垂直激光束和参考线段成 45 度角或 90 度角。
