440R说明书

440R说明书

的部分仅适用于KTS440R型全站仪。

使用仪器之前请仔细阅读！注：厂家保留对技术参数进行更改而不事先通知的权利！一、特点1、功能全面科力达KTS440(R)(L)全站仪除具备丰富的测量程序，还同时具有参数设置、数据存储等功能，适用于进行各种专业测量和工程测量。

2、强大的内存管理采用大容量内存，可存储测量数据或坐标数据14000个，并可以方便地进行内存管理，实现数据的增加、删除、修改、传输。

3、绝对编码度盘预装绝对数码度盘，仪器开机即可直接进行测量。

即使中途重置电源，方位角信息也不会丢失。

12、免棱镜型KTS440R系列全站仪发射光是激光，使用时不能对准眼睛。

三、安全指南内置测距仪（可见激光）警告：全站仪配备激光等级3R / Ⅲa测距仪由以下标识辨认：在仪器正镜垂直制微动上方贴有提示标签：”3A类激光产品”，对面也有一张同样的标签。

该产品属于Class 3R级激光产品，根据下列标准IEC 60825-1：2001 “激光产品的辐射安全”。

Class 3R / Ⅲa激光产品：连续观察激光束是有害的，要避免激光直射眼睛。

在波长400nm-700nm能达到发射极限在Class 2 / Ⅱ的五倍以内。

警告：连续直视激光束是有害的。

预防：不要用眼睛盯着激光束看，也不要用激光束指向别人。

反射光束对仪器来说都是有效测量。

警告：当激光束照射在如棱镜、平面镜、金属表面、窗户上时，用眼睛直接观看反射光可能具有危险性。

预防：不要盯着激光反射的地方看。

在激光开关打开时（测距模式），不要在激光光路或棱镜旁边看。

只能通过全站仪的望远镜观看照准棱镜。

警告：不正确使用Class 3R激光设备是有危险性的。

预防：要避免造成伤害，让每个使用者都切实做好安全预防措施，必须在可能发生危害的距离内（依标准IEC60825-1:2001）做好控制。

下面是有关标准的主要部分的解释：Class 3R级激光产品在室外和建筑工地使用（测量、定线、操平）。
