一(yi)、使用方法 

多檔位定時設定 

1.儀器在(zai)使用(yong)前(qian)應充(chong)足電(dian)，根據采(cai)(cai)(cai)樣(yang)需要設置(zhi)采(cai)(cai)(cai)樣(yang)時(shi)間(jian)，然后波動數碼開(kai)(kai)關鍵至相(xiang)應的(de)定時(shi)檔位(如“3”位置(zhi)，此(ci)時(shi)采(cai)(cai)(cai)樣(yang)工作時(shi)間(jian)為4小時(shi))。并將采(cai)(cai)(cai)用(yong)器的(de)電(dian)源開(kai)(kai)關向上打開(kai)(kai)，此(ci)時(shi)指示燈亮，表明采(cai)(cai)(cai)樣(yang)開(kai)(kai)始。定時(shi)精度(du)可用(yong)秒表校核。 

2.儀(yi)(yi)器在(zai)采集(ji)氣體時(shi)，首先在(zai)進氣口接(jie)上過濾器，以(yi)免(mian)將液體或顆粒(li)吸(xi)進機(ji)內(nei)影(ying)響流量，如與固體吸(xi)附管(guan)配套采樣，液體也不(bu)能進入吸(xi)附管(guan)內(nei)，以(yi)免(mian)造成吸(xi)附劑膨(peng)脹，使儀(yi)(yi)器不(bu)能正常工作。如果不(bu)慎吸(xi)入機(ji)中(zhong)，應立即注入蒸餾水(shui)，清洗(xi)幾(ji)次，再(zai)吸(xi)入無水(shui)乙(yi)醇，并將儀(yi)(yi)器空(kong)載運轉半小時(shi)左右，使無水(shui)乙(yi)醇充分排出，一般都能恢(hui)復正常技術(shu)指標。 

3.儀器應充足電(dian)(dian)放置(zhi)，若長期不使用，每隔2-3個月需要維護性充電(dian)(dian)一次，以確保(bao)電(dian)(dian)池具有(you)良好的性能。切(qie)勿用非本儀器配(pei)套的專用電(dian)(dian)源充電(dian)(dian)。 

4.儀器(qi)處(chu)于關機狀態(tai)時應將調節閥(fa)手柄(bing)松開(kai)，以免調節閥(fa)手柄(bing)長期(qi)壓迫氣管而影響(xiang)流量。 

1.采樣前(qian)的準備(bei)： 

選配內置電(dian)(dian)(dian)(dian)(dian)池(chi)：該(gai)儀器應(ying)選用(yong)6節(jie)5#1.5V干電(dian)(dian)(dian)(dian)(dian)池(chi)或1.2V鎳(nie)氫(qing)高容量充(chong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)池(chi)作(zuo)(zuo)為(wei)內置工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)。裝備電(dian)(dian)(dian)(dian)(dian)池(chi)應(ying)打開電(dian)(dian)(dian)(dian)(dian)池(chi)后蓋，裝入電(dian)(dian)(dian)(dian)(dian)池(chi)盒中，并按開始(shi)鍵檢查內置電(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)量是否(fou)符合儀器工作(zuo)(zuo)和(he)采(cai)(cai)樣要(yao)求。如果儀器顯示欠(qian)壓(ya)(ya)或達不到采(cai)(cai)樣時間要(yao)求，應(ying)立即充(chong)電(dian)(dian)(dian)(dian)(dian)或改用(yong)專用(yong)穩(wen)定(ding)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)，充(chong)電(dian)(dian)(dian)(dian)(dian)時間一般需16小時左右。(穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)220V50HZ，輸出電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)9V，電(dian)(dian)(dian)(dian)(dian)流300MA)。穩(wen)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)作(zuo)(zuo)為(wei)工作(zuo)(zuo)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)供(gong)電(dian)(dian)(dian)(dian)(dian)應(ying)撥至穩(wen)壓(ya)(ya)位，插(cha)入電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)插(cha)孔，并接(jie)通(tong)220V50HZ交流電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)即可。 

二、注意(yi)事項 

1.采樣(yang)時必(bi)須(xu)連接過濾器，才能(neng)確保采樣(yang)工作效能(neng)。 

2.在采樣或自動關機時間設定中顯示自動閃爍，表示欠壓，應及時給儀器補充電。(標準充電時間需16小時) 

3.若(ruo)長時(shi)間儀器不使用，應定期每月給電(dian)池組進行維護性補充電(dian)，以(yi)確保電(dian)池具有良好的工作性能。
