溫度(du)曲(qu)(qu)線出現異(yi)常l請確認(ren)曲(qu)(qu)線異(yi)常的地方是否為光纖熔接點。l請檢查光纖連接頭。如果光纖連接頭污染，或者(zhe)受損(sun)，將影響溫度(du)曲(qu)(qu)線。

請(qing)查(cha)看(kan)光(guang)纖(xian)是否彎折(zhe)。如果出現彎折(zhe)，請(qing)將光(guang)纖(xian)取直。如果光(guang)纖(xian)取直后，曲線(xian)仍異常，說明光(guang)纖(xian)已損壞，請(qing)更換光(guang)纖(xian)。

光纖末端(duan)一部分沒有測(ce)量數(shu)據由于光纖尾端(duan)的(de)端(duan)面反射比較大，會(hui)影響前端(duan)的(de)溫(wen)度測(ce)量，因此(ci)扣(kou)除尾端(duan)5m左右的(de)溫(wen)度測(ce)量數(shu)據。

光纖(xian)末段5m加熱沒有報警理(li)由同上。光纖(xian)尾端的斷面(mian)反射比較大，扣除了(le)尾端5m左右的溫度測量數據。

光(guang)纖頭(tou)部(bu)20m溫度測(ce)(ce)量不準確由于光(guang)纖頭(tou)部(bu)的反(fan)射光(guang)比較大，影響(xiang)頭(tou)部(bu)20m范圍(wei)內的溫度測(ce)(ce)量值(zhi)，可能造(zao)成誤報，因此光(guang)纜布設時需(xu)扣除(chu)前段(duan)20m，推薦將(jiang)頭(tou)部(bu)20m盤繞(rao)在機(ji)柜內。

插(cha)拔(ba)光(guang)(guang)纖(xian)時(shi)出現誤(wu)報警插(cha)拔(ba)光(guang)(guang)纖(xian)時(shi)由于(yu)長度發生(sheng)變化，可(ke)能造成溫度測(ce)量(liang)異(yi)常以及誤(wu)報警。因此，若(ruo)需插(cha)拔(ba)光(guang)(guang)纖(xian)，請(qing)先停止測(ce)量(liang)。

光(guang)纖斷(duan)裂瞬間出現誤報警系統能自動檢(jian)測光(guang)纖斷(duan)裂情況，并(bing)準確定位斷(duan)纖位置(zhi)。由(you)于光(guang)纖長度發生變化，光(guang)纖斷(duan)裂瞬間可能造(zao)成(cheng)(cheng)溫度測量異常，并(bing)造(zao)成(cheng)(cheng)誤報警。
