二. 使用说明
1．仪器简介
wt系列微型比色计（水质分析仪）是以发光二级管作为单色光源，采用微处理器控制的微型光度计，广泛适用于实验室及野外的测量工作。仪器中已经预置了常用的水质分析指标的测量程序。本仪器具有以下特点：
u 直接显示待测物的浓度，同时显示吸光度值。
u 友好的人机界面，汉字菜单能指导用户操作。
u 内建时钟，能够记录测量日期与时间。
u 500组测量数据的*保存与自动刷新
仪器采用四节5号碱性干电池供电。在室内测定时，也可使用外接电源供电。
1.1 仪器的启封
将仪器和配件从货运箱中取出，仔细检查各个部分在运输过程中是否有所损坏，并清点包装单上所列物品是否齐全。若有损坏或缺失，请与产品经销商。
