1)電子皮帶秤探(tan)測(ce)器信(xin)號(hao)受(shou)干擾。前(qian)放板接(jie)(jie)收電離室產生的(de)(de)微弱電流(liu)信(xin)號(hao).放大后(hou)通過(guo)屏(ping)蔽電纜傳送給(gei)主(zhu)(zhu)機。如(ru)果電磁干擾過(guo)大或主(zhu)(zhu)機端(duan)屏(ping)蔽接(jie)(jie)地不(bu)良(liang)，信(xin)號(hao)受(shou)到干擾會產生較大的(de)(de)波動(dong)。處理這種問(wen)題，屏(ping)蔽線探(tan)測(ce)器端(duan)應懸(xuan)空，主(zhu)(zhu)機端(duan)要保(bao)證良(liang)好接(jie)(jie)地，還應注意(yi)電離室與套筒隔離。

　　2)電(dian)離(li)室(shi)(shi)(shi)(shi)及前放板受(shou)(shou)潮(chao)(chao)。現場有時(shi)濕度太(tai)大而套筒橡膠墊又密(mi)封不嚴(yan)，會(hui)使(shi)電(dian)離(li)室(shi)(shi)(shi)(shi)高壓(ya)極(ji)(ji)、收(shou)集(ji)極(ji)(ji)的陶瓷絕緣(yuan)(yuan)子受(shou)(shou)潮(chao)(chao)產生漏電(dian)流，前放板受(shou)(shou)潮(chao)(chao)使(shi)負(fu)高壓(ya)不足同樣會(hui)使(shi)電(dian)離(li)室(shi)(shi)(shi)(shi)電(dian)流比平時(shi)變小。可(ke)對電(dian)離(li)室(shi)(shi)(shi)(shi)電(dian)極(ji)(ji)陶瓷絕緣(yuan)(yuan)子的絕緣(yuan)(yuan)性能(neng)進(jin)行檢查，使(shi)用1000V或(huo)2500V兆(zhao)歐表分別測試(shi)高壓(ya)極(ji)(ji)和收(shou)集(ji)極(ji)(ji)對外殼的絕緣(yuan)(yuan)電(dian)阻，應該(gai)指示無窮大，否則使(shi)用干凈或(huo)酒(jiu)精(jing)棉球(qiu)多(duo)遍擦洗，最后(hou)用電(dian)吹風吹干，以保證絕緣(yuan)(yuan)子干燥潔(jie)凈。

　　3)電(dian)(dian)子元器件(jian)特性不穩。前(qian)放板(ban)中的高阻阻值達到5Gl,溫度系數較大，因(yin)此核子秤在(zai)套筒內(nei)使(shi)(shi)(shi)用加(jia)熱帶等裝置對電(dian)(dian)離(li)室(shi)及前(qian)放板(ban)進行整體加(jia)熱恒溫，以使(shi)(shi)(shi)其免受環(huan)境溫度變化的影響。于長期處于較高的溫度下，某些元器件(jian)的質量下降，特性不穩，造成信(xin)號波動。如高壓系統電(dian)(dian)容漏電(dian)(dian)會使(shi)(shi)(shi)電(dian)(dian)離(li)室(shi)電(dian)(dian)極(ji)上出(chu)現交變電(dian)(dian)容致使(shi)(shi)(shi)輸出(chu)信(xin)號大幅波動，濾(lv)波電(dian)(dian)容損壞將使(shi)(shi)(shi)信(xin)號噪聲電(dian)(dian)壓大幅提高。
