二. 使用說明
1．儀器簡介
WT系列微型比色計(jì)（水質(zhì)分析儀）是以發(fā)光二級(jí)管作為單色光源，采用微處理器控制的微型光度計(jì)，廣泛適用于實(shí)驗(yàn)室及野外的測量工作。儀器中已經(jīng)預(yù)置了常用的水質(zhì)分析指標(biāo)的測量程序。本儀器具有以下特點(diǎn)：
u 直接顯示待測物的濃度，同時(shí)顯示吸光度值。
u 友好的人機(jī)界面，漢字菜單能指導(dǎo)用戶操作。
u 內(nèi)建時(shí)鐘，能夠記錄測量日期與時(shí)間。
u 500組測量數(shù)據(jù)的*保存與自動(dòng)刷新
儀器采用四節(jié)5號(hào)堿性干電池供電。在室內(nèi)測定時(shí)，也可使用外接電源供電。
1.1 儀器的啟封
將儀器和配件從貨運(yùn)箱中取出，仔細(xì)檢查各個(gè)部分在運(yùn)輸過程中是否有所損壞，并清點(diǎn)包裝單上所列物品是否齊全。若有損壞或缺失，請(qǐng)與產(chǎn)品經(jīng)銷商。
標(biāo)準(zhǔn)件
u 儀器主機(jī)(含暗室蓋) 1個(gè)
u 電源適配器 1個(gè)
