檢修流程：

檢查信號線(xian)(xian)(xian)(xian)是否(fou)(fou)斷裂，主線(xian)(xian)(xian)(xian)與儀表(biao)接(jie)頭焊點是否(fou)(fou)脫落 ，接(jie)線(xian)(xian)(xian)(xian)盒里面里接(jie)線(xian)(xian)(xian)(xian)是否(fou)(fou)良好等(deng)等(deng)，這(zhe)些(xie)都可(ke)能導致這(zhe)個(ge)癥狀的發生(sheng)。有(you)(you)些(xie)秤(cheng)體至儀表(biao)之間距離過大，其(qi)間主線(xian)(xian)(xian)(xian)有(you)(you)外露部(bu)分，有(you)(you)可(ke)能被人為破壞或(huo)(huo)老鼠啃咬，金屬屏蔽失去(qu)作用(yong)或(huo)(huo)連接(jie)處不牢，造成(cheng)數字跳變。用(yong)萬用(yong)表(biao)電(dian)阻檔(dang)測量(liang)該主線(xian)(xian)(xian)(xian)，以確保(bao)每一股都是獨的通道，并且連線(xian)(xian)(xian)(xian)牢固，否(fou)(fou)則更換主線(xian)(xian)(xian)(xian)。其(qi)重點是，一定要(yao)仔細確認接(jie)線(xian)(xian)(xian)(xian)是否(fou)(fou)有(you)(you)問題。如(ru)若接(jie)線(xian)(xian)(xian)(xian)是好的，那么(me)再請檢查儀表(biao)是否(fou)(fou)正(zheng)常，必要(yao)時可(ke)開封檢查儀表(biao)內部(bu)連接(jie)線(xian)(xian)(xian)(xian)是否(fou)(fou)正(zheng)常。

檢查接線(xian)(xian)(xian)盒(he)(he)內(nei)(nei)電(dian)路板是否損壞。接線(xian)(xian)(xian)盒(he)(he)內(nei)(nei)的電(dian)路板是由接線(xian)(xian)(xian)端子盒(he)(he)和幾(ji)組(zu)多(duo)(duo)圈(quan)電(dian)阻組(zu)成(cheng)。接線(xian)(xian)(xian)端子長期使用(yong)可致氧化銹(xiu)蝕(shi)，接頭處氧化銹(xiu)蝕(shi)部(bu)分脫落，導(dao)致壓(ya)線(xian)(xian)(xian)松動，從而使儀(yi)表(biao)數字跳(tiao)變。此時(shi)，可用(yong)砂紙或銼(cuo)刀摩擦掉(diao)其接觸面(mian)，重新(xin)連接牢固(gu)，故障現象(xiang)排除。多(duo)(duo)圈(quan)電(dian)阻長期使用(yong)也可導(dao)致內(nei)(nei)部(bu)金(jin)屬表(biao)面(mian)被氧化，使得(de)數字不穩、跳(tiao)變，此時(shi)用(yong)更換相同阻值的多(duo)(duo)圈(quan)電(dian)阻即可排除故障
