检查水平方向的激光束的找平精度
针对这项检验,您需要一个无障碍物的 5 x 5 米空旷场
地。
将测量仪器放在两道墙 A B 的中间。 可以把仪器
固定在支架,一般的三脚架,或把测量仪器放置在
平坦,坚固的底垫上。让测量仪器找平。
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)
A 上点 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
=2 x 5 x 0,3 毫米 / = 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。
把测量仪器放置在距离门孔 2,5 米处的坚实,平坦
的地面上 (不可以使用三脚架) 把激光束朝向门
孔并且让测量仪器找平。
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)。
