檢修流程：

檢(jian)(jian)查信號線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)斷(duan)裂，主線(xian)(xian)(xian)(xian)與儀表接(jie)(jie)(jie)頭焊點(dian)是(shi)(shi)否(fou)(fou)脫落 ，接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)盒里(li)面里(li)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)良好(hao)等等，這些都可能(neng)導(dao)致這個癥狀的發生。有些秤(cheng)體至(zhi)儀表之間距離(li)過(guo)大，其(qi)間主線(xian)(xian)(xian)(xian)有外露部(bu)分(fen)，有可能(neng)被人為破壞或老鼠啃(ken)咬，金屬屏蔽(bi)失去(qu)作用或連接(jie)(jie)(jie)處不牢，造成數字跳變。用萬用表電阻檔(dang)測(ce)量該主線(xian)(xian)(xian)(xian)，以確(que)保(bao)每(mei)一股都是(shi)(shi)獨的通道，并(bing)且連線(xian)(xian)(xian)(xian)牢固，否(fou)(fou)則更換主線(xian)(xian)(xian)(xian)。其(qi)重點(dian)是(shi)(shi)，一定要仔細(xi)確(que)認接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)有問題。如若(ruo)接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)好(hao)的，那么再請(qing)檢(jian)(jian)查儀表是(shi)(shi)否(fou)(fou)正(zheng)常，必要時可開封檢(jian)(jian)查儀表內部(bu)連接(jie)(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)正(zheng)常。

檢查接(jie)(jie)線(xian)盒(he)(he)內(nei)電(dian)(dian)路板(ban)是否損壞。接(jie)(jie)線(xian)盒(he)(he)內(nei)的(de)電(dian)(dian)路板(ban)是由接(jie)(jie)線(xian)端子(zi)盒(he)(he)和幾(ji)組多(duo)圈電(dian)(dian)阻(zu)(zu)組成。接(jie)(jie)線(xian)端子(zi)長(chang)期使用可致(zhi)氧(yang)化(hua)銹(xiu)蝕，接(jie)(jie)頭處(chu)氧(yang)化(hua)銹(xiu)蝕部(bu)分脫落(luo)，導致(zhi)壓線(xian)松動(dong)，從而使儀(yi)表(biao)數字(zi)跳(tiao)變。此時(shi)，可用砂紙或銼刀摩擦掉其接(jie)(jie)觸(chu)面，重(zhong)新連接(jie)(jie)牢(lao)固，故障現象(xiang)排除。多(duo)圈電(dian)(dian)阻(zu)(zu)長(chang)期使用也可導致(zhi)內(nei)部(bu)金屬表(biao)面被氧(yang)化(hua)，使得數字(zi)不穩(wen)、跳(tiao)變，此時(shi)用更換相同阻(zu)(zu)值的(de)多(duo)圈電(dian)(dian)阻(zu)(zu)即可排除故障
