氧氮?dú)浞治鰞x的常見故障及解決方法供電正常、通訊正常，點(diǎn)擊確認(rèn)鍵后分析儀不工作。這是沒有水流，爐子溫度太高或儀器通道電壓不正常。如沒有水流，爐子溫度太高這些信息會(huì)顯示在顯示器畫面上，但沒有信息顯示說明這兩項(xiàng)正常。接下來檢查儀器通道零位電壓，如果比±3V高出1V以上，可能是因?yàn)闅馄靠樟?，或者是空氣進(jìn)入到分析儀中。檢查并更換化學(xué)試劑，如果有空氣進(jìn)入熱導(dǎo)池里，熱導(dǎo)池的電壓就會(huì)＜-6V，此時(shí)打開右面的門，堵住爐子氣體進(jìn)口，10s后，熱導(dǎo)池電壓值必然升高。經(jīng)過逐一排查，**終確認(rèn)堿石棉有問題，更換后儀器正常。上海禹重實(shí)業(yè)有限公司為您提供分析儀，歡迎新老客戶來電！松江分析儀
