1、在試(shi)驗(yan)運行過程中(zhong)(zhong)突然出現(xian)故(gu)障(zhang)時，控制儀表上出現(xian)對應的(de)(de)(de)故(gu)障(zhang)顯示提(ti)示并有聲訊報(bao)警(jing)提(ti)示。操(cao)作人員可以對照設(she)備的(de)(de)(de)操(cao)作使用中(zhong)(zhong)的(de)(de)(de)故(gu)障(zhang)排除一章中(zhong)(zhong)快速(su)檢(jian)查出屬于哪一類故(gu)障(zhang)，即可請專業人員快速(su)排除故(gu)障(zhang)，以確保試(shi)驗(yan)的(de)(de)(de)正常(chang)進行。其它環境試(shi)驗(yan)設(she)備在使用中(zhong)(zhong)還會有其它的(de)(de)(de)現(xian)象(xiang)，那就(jiu)要具(ju)體現(xian)象(xiang)，具(ju)體分(fen)析和排除。

2、在高溫(wen)(wen)(wen)(wen)試驗中，如(ru)(ru)溫(wen)(wen)(wen)(wen)度(du)(du)變化(hua)達不到(dao)試驗溫(wen)(wen)(wen)(wen)度(du)(du)值時，可以檢(jian)查電(dian)器(qi)系(xi)統(tong)，逐一(yi)排除(chu)故障。如(ru)(ru)恒(heng)(heng)溫(wen)(wen)(wen)(wen)恒(heng)(heng)濕試驗箱溫(wen)(wen)(wen)(wen)度(du)(du)升得很慢，就要查看風循環系(xi)統(tong)，看一(yi)下(xia)風循環的調節擋板是否開啟正常，反之，就檢(jian)查風循環的電(dian)機運轉(zhuan)是否正常。如(ru)(ru)溫(wen)(wen)(wen)(wen)度(du)(du)過(guo)沖厲害(hai)那么就需要整定PID的設(she)置(zhi)參數。如(ru)(ru)果溫(wen)(wen)(wen)(wen)度(du)(du)直接上升，那么控制器(qi)出故障，須更換控制儀表。

3、在做濕(shi)(shi)(shi)熱試(shi)驗中，出現實際濕(shi)(shi)(shi)度(du)(du)會(hui)達到100%或者(zhe)(zhe)實際濕(shi)(shi)(shi)度(du)(du)與目標濕(shi)(shi)(shi)度(du)(du)相(xiang)差(cha)很大，數值低得很多，前者(zhe)(zhe)的(de)現象：可(ke)能是(shi)(shi)(shi)(shi)濕(shi)(shi)(shi)球(qiu)傳感(gan)器(qi)(qi)(qi)上(shang)的(de)紗布(bu)干(gan)燥(zao)引(yin)起，那(nei)就要(yao)檢查(cha)濕(shi)(shi)(shi)球(qiu)傳感(gan)器(qi)(qi)(qi)的(de)水(shui)(shui)(shui)(shui)(shui)槽中是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)缺水(shui)(shui)(shui)(shui)(shui)，水(shui)(shui)(shui)(shui)(shui)槽中的(de)水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)是(shi)(shi)(shi)(shi)由(you)一(yi)水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)控制(zhi)器(qi)(qi)(qi)自動控制(zhi)的(de)，查(cha)水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)控制(zhi)器(qi)(qi)(qi)供水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)供水(shui)(shui)(shui)(shui)(shui)正(zheng)常(chang)，水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)控制(zhi)器(qi)(qi)(qi)工作(zuo)是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)正(zheng)常(chang)。另一(yi)種可(ke)能就是(shi)(shi)(shi)(shi)濕(shi)(shi)(shi)球(qiu)紗布(bu)因(yin)(yin)使用時間長，或供水(shui)(shui)(shui)(shui)(shui)水(shui)(shui)(shui)(shui)(shui)質純凈度(du)(du)的(de)原因(yin)(yin)，會(hui)使紗布(bu)變硬，使紗布(bu)無法吸收水(shui)(shui)(shui)(shui)(shui)份而干(gan)燥(zao)，只要(yao)更(geng)換或清洗紗布(bu)即可(ke)排除(chu)以(yi)上(shang)現象。后者(zhe)(zhe)的(de)現象主(zhu)要(yao)是(shi)(shi)(shi)(shi)恒(heng)溫恒(heng)濕(shi)(shi)(shi)試(shi)驗箱(xiang)的(de)加(jia)濕(shi)(shi)(shi)系(xi)(xi)統(tong)(tong)不(bu)工作(zuo)，查(cha)看加(jia)濕(shi)(shi)(shi)系(xi)(xi)統(tong)(tong)的(de)供水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)，供水(shui)(shui)(shui)(shui)(shui)系(xi)(xi)統(tong)(tong)內是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)有一(yi)定的(de)水(shui)(shui)(shui)(shui)(shui)量，控制(zhi)加(jia)濕(shi)(shi)(shi)鍋(guo)爐水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)的(de)水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)控制(zhi)是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)正(zheng)常(chang)，加(jia)濕(shi)(shi)(shi)鍋(guo)爐內的(de)水(shui)(shui)(shui)(shui)(shui)位(wei)(wei)(wei)(wei)(wei)是(shi)(shi)(shi)(shi)否(fou)(fou)(fou)正(zheng)常(chang)。如以(yi)上(shang)一(yi)切(qie)都正(zheng)常(chang)，那(nei)就要(yao)檢查(cha)電(dian)器(qi)(qi)(qi)控制(zhi)系(xi)(xi)統(tong)(tong)，這(zhe)要(yao)請專(zhuan)業維修人員進行(xing)檢修。

4、恒(heng)(heng)溫(wen)(wen)(wen)(wen)恒(heng)(heng)濕(shi)試驗(yan)箱(xiang)低(di)溫(wen)(wen)(wen)(wen)達不到(dao)試驗(yan)的(de)(de)指標，那你就(jiu)(jiu)要(yao)(yao)觀察溫(wen)(wen)(wen)(wen)度(du)(du)的(de)(de)變化，分清楚是溫(wen)(wen)(wen)(wen)度(du)(du)降的(de)(de)很(hen)慢，還是溫(wen)(wen)(wen)(wen)度(du)(du)到(dao)一(yi)定值(zhi)后(hou)溫(wen)(wen)(wen)(wen)度(du)(du)有回升(sheng)的(de)(de)趨勢。前者就(jiu)(jiu)要(yao)(yao)檢(jian)查一(yi)下，做低(di)溫(wen)(wen)(wen)(wen)試驗(yan)前是否將(jiang)工作(zuo)室(shi)烘(hong)干(gan)，使(shi)(shi)工作(zuo)室(shi)保(bao)持(chi)干(gan)燥后(hou)再(zai)將(jiang)試驗(yan)樣(yang)品放(fang)入工作(zuo)室(shi)內(nei)(nei)再(zai)做試驗(yan)，工作(zuo)室(shi)內(nei)(nei)的(de)(de)試驗(yan)樣(yang)品是否放(fang)置(zhi)的(de)(de)過多，使(shi)(shi)工作(zuo)室(shi)內(nei)(nei)的(de)(de)風不能(neng)充分循環(huan)(huan)，在排除上述(shu)原因后(hou)，就(jiu)(jiu)要(yao)(yao)考慮是否是制冷系統中的(de)(de)故(gu)障了，這樣(yang)就(jiu)(jiu)要(yao)(yao)請廠家(jia)的(de)(de)專業人(ren)員進行檢(jian)修。后(hou)者的(de)(de)現象是恒(heng)(heng)溫(wen)(wen)(wen)(wen)恒(heng)(heng)濕(shi)試驗(yan)箱(xiang)設(she)(she)備的(de)(de)使(shi)(shi)用環(huan)(huan)境不好(hao)所(suo)致，設(she)(she)備放(fang)置(zhi)的(de)(de)環(huan)(huan)境溫(wen)(wen)(wen)(wen)度(du)(du)，放(fang)置(zhi)的(de)(de)位置(zhi)（箱(xiang)體后(hou)與墻的(de)(de)距(ju)離）要(yao)(yao)滿足要(yao)(yao)求（在設(she)(she)備操作(zuo)使(shi)(shi)用說(shuo)明(ming)中都有規(gui)定）。
