1.設(she)備(bei)在試驗運行過(guo)程中(zhong)(zhong)突(tu)然出現(xian)故(gu)障時(shi)，控制儀(yi)表上出現(xian)對(dui)應的(de)(de)故(gu)障顯示提示并有聲訊報警提示。操(cao)作人(ren)員可(ke)以對(dui)照設(she)備(bei)的(de)(de)操(cao)作使用中(zhong)(zhong)的(de)(de)故(gu)障排除一章(zhang)中(zhong)(zhong)快(kuai)速(su)檢(jian)查出屬于哪一類故(gu)障，即(ji)可(ke)請專業人(ren)員快(kuai)速(su)排除故(gu)障，以確保試驗的(de)(de)正常進行。

　　2.在高(gao)溫(wen)(wen)(wen)試驗中，如(ru)(ru)溫(wen)(wen)(wen)度變(bian)化(hua)達不到試驗溫(wen)(wen)(wen)度值(zhi)時，可以檢查(cha)(cha)電器(qi)系統(tong)，逐一排除故(gu)障。如(ru)(ru)溫(wen)(wen)(wen)度升(sheng)得很(hen)慢(man)，就(jiu)要(yao)查(cha)(cha)看(kan)風(feng)(feng)循(xun)環(huan)系統(tong)，看(kan)一下(xia)風(feng)(feng)循(xun)環(huan)的調節擋板是(shi)否開(kai)啟正常，反之，就(jiu)檢查(cha)(cha)風(feng)(feng)循(xun)環(huan)的電機運轉是(shi)否正常。如(ru)(ru)溫(wen)(wen)(wen)度過沖(chong)厲害那么(me)就(jiu)需要(yao)整(zheng)定PID 的設置參(can)數。如(ru)(ru)果溫(wen)(wen)(wen)度直(zhi)接(jie)上升(sheng)，過溫(wen)(wen)(wen)保護(hu)，那么(me)，控制器(qi)出故(gu)障，須(xu)更換控制儀(yi)表。

　　3.低溫(wen)(wen)(wen)(wen)達不(bu)(bu)到試(shi)(shi)驗(yan)的(de)指標，那你(ni)就(jiu)要觀察(cha)溫(wen)(wen)(wen)(wen)度(du)的(de)變化，是(shi)(shi)(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)降(jiang)的(de)很慢，還是(shi)(shi)(shi)(shi)(shi)溫(wen)(wen)(wen)(wen)度(du)到一(yi)定(ding)值(zhi)后(hou)(hou)溫(wen)(wen)(wen)(wen)度(du)有(you)回升的(de)趨勢，前者就(jiu)要檢(jian)查一(yi)下，做低溫(wen)(wen)(wen)(wen)試(shi)(shi)驗(yan)前是(shi)(shi)(shi)(shi)(shi)否(fou)(fou)將(jiang)工作(zuo)(zuo)室烘干(gan)，使工作(zuo)(zuo)室保持(chi)干(gan)燥后(hou)(hou)再將(jiang)試(shi)(shi)驗(yan)樣品放(fang)入工作(zuo)(zuo)室內(nei)(nei)再做試(shi)(shi)驗(yan)，工作(zuo)(zuo)室內(nei)(nei)的(de)試(shi)(shi)驗(yan)樣品是(shi)(shi)(shi)(shi)(shi)否(fou)(fou)放(fang)置(zhi)的(de)過多，使工作(zuo)(zuo)室內(nei)(nei)的(de)風不(bu)(bu)能充分循環(huan)，在(zai)(zai)排除上述(shu)原因后(hou)(hou)，就(jiu)要考慮是(shi)(shi)(shi)(shi)(shi)否(fou)(fou)是(shi)(shi)(shi)(shi)(shi)制冷系統(tong)中的(de)故障了，這樣就(jiu)要請廠家(jia)的(de)專業人員(yuan)進行檢(jian)修。后(hou)(hou)者的(de)現象是(shi)(shi)(shi)(shi)(shi)設(she)備的(de)使用環(huan)境(jing)不(bu)(bu)好所致，設(she)備放(fang)置(zhi)的(de)環(huan)境(jing)溫(wen)(wen)(wen)(wen)度(du)，放(fang)置(zhi)的(de)位置(zhi)(箱(xiang)體(ti)后(hou)(hou)與墻的(de)距離)要滿足要求(在(zai)(zai)設(she)備操作(zuo)(zuo)使用說(shuo)明(ming)中都有(you)規定(ding))。

　　4.在做濕(shi)(shi)熱試驗中，出現(xian)(xian)實際濕(shi)(shi)度(du)(du)會(hui)達(da)到(dao)100%或者(zhe)(zhe)實際濕(shi)(shi)度(du)(du)與目標濕(shi)(shi)度(du)(du)相差很大，數值低得(de)很多，前者(zhe)(zhe)的(de)(de)現(xian)(xian)象(xiang):可(ke)(ke)能是(shi)濕(shi)(shi)球(qiu)傳感(gan)(gan)器(qi)(qi)上的(de)(de)紗布(bu)干燥(zao)引起，那就要(yao)(yao)檢查濕(shi)(shi)球(qiu)傳感(gan)(gan)器(qi)(qi)的(de)(de)水(shui)槽中是(shi)否(fou)缺水(shui)，水(shui)槽中的(de)(de)水(shui)位(wei)是(shi)由一(yi)水(shui)位(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)自動控(kong)(kong)(kong)制(zhi)的(de)(de)，查水(shui)位(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)供(gong)(gong)水(shui)系(xi)統(tong)(tong)(tong)是(shi)否(fou)供(gong)(gong)水(shui)正(zheng)常(chang)，水(shui)位(wei)控(kong)(kong)(kong)制(zhi)器(qi)(qi)工作是(shi)否(fou)正(zheng)常(chang)。另(ling)一(yi)種可(ke)(ke)能就是(shi)濕(shi)(shi)球(qiu)紗布(bu)因使用時間長，或供(gong)(gong)水(shui)水(shui)質純(chun)凈度(du)(du)的(de)(de)原因，會(hui)使紗布(bu)變(bian)硬(ying)，使紗布(bu)無法(fa)吸收水(shui)份(fen)而干燥(zao)，只要(yao)(yao)更換(huan)或清(qing)洗紗布(bu)即可(ke)(ke)排除以(yi)(yi)上現(xian)(xian)象(xiang)。后(hou)者(zhe)(zhe)的(de)(de)現(xian)(xian)象(xiang)主要(yao)(yao)是(shi)加(jia)濕(shi)(shi)系(xi)統(tong)(tong)(tong)不工作，查看加(jia)濕(shi)(shi)系(xi)統(tong)(tong)(tong)的(de)(de)供(gong)(gong)水(shui)系(xi)統(tong)(tong)(tong)，供(gong)(gong)水(shui)系(xi)統(tong)(tong)(tong)內(nei)是(shi)否(fou)有一(yi)定的(de)(de)水(shui)量，控(kong)(kong)(kong)制(zhi)加(jia)濕(shi)(shi)鍋爐水(shui)位(wei)的(de)(de)水(shui)位(wei)控(kong)(kong)(kong)制(zhi)是(shi)否(fou)正(zheng)常(chang)，加(jia)濕(shi)(shi)鍋爐內(nei)的(de)(de)水(shui)位(wei)是(shi)否(fou)正(zheng)常(chang)。如以(yi)(yi)上一(yi)切都(dou)正(zheng)常(chang)，那就要(yao)(yao)檢查電(dian)器(qi)(qi)控(kong)(kong)(kong)制(zhi)系(xi)統(tong)(tong)(tong)，這要(yao)(yao)請專業維修(xiu)人員進行檢修(xiu)。

　　其它環境試驗設備在使用中還會有其它的現象，那就要具體現象，具體分析和排除。小型高低溫濕熱試驗箱還要定期(qi)進(jin)行維護保養(yang)，制冷(leng)系(xi)統的冷(leng)凝器定期(qi)清理，對于活動部件應按說明書(shu)加油潤滑，電器控制系(xi)統定期(qi)維護檢(jian)查等(deng)等(deng)，這些(xie)工作是*的。
