檢修流程：

檢查(cha)信號線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)斷裂，主(zhu)線(xian)(xian)(xian)(xian)與儀(yi)(yi)表(biao)(biao)接(jie)頭焊點(dian)是(shi)(shi)否(fou)(fou)脫(tuo)落 ，接(jie)線(xian)(xian)(xian)(xian)盒里(li)面(mian)里(li)接(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)良好等等，這些都可(ke)能(neng)導致(zhi)這個癥狀的(de)(de)發生。有(you)(you)些秤(cheng)體(ti)至(zhi)儀(yi)(yi)表(biao)(biao)之間距離過大，其間主(zhu)線(xian)(xian)(xian)(xian)有(you)(you)外露部(bu)(bu)分，有(you)(you)可(ke)能(neng)被人為破壞或(huo)老鼠啃咬，金屬屏蔽失去(qu)作(zuo)用或(huo)連接(jie)處不牢(lao)，造(zao)成(cheng)數字(zi)跳變。用萬用表(biao)(biao)電阻(zu)檔測量該主(zhu)線(xian)(xian)(xian)(xian)，以確保每(mei)一(yi)股都是(shi)(shi)獨(du)的(de)(de)通道，并(bing)且連線(xian)(xian)(xian)(xian)牢(lao)固，否(fou)(fou)則更換(huan)主(zhu)線(xian)(xian)(xian)(xian)。其重點(dian)是(shi)(shi)，一(yi)定要(yao)仔(zi)細確認接(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)有(you)(you)問(wen)題。如若接(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)好的(de)(de)，那么再請(qing)檢查(cha)儀(yi)(yi)表(biao)(biao)是(shi)(shi)否(fou)(fou)正常(chang)，必(bi)要(yao)時(shi)可(ke)開(kai)封檢查(cha)儀(yi)(yi)表(biao)(biao)內部(bu)(bu)連接(jie)線(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)正常(chang)。

檢查接線盒(he)內電(dian)路(lu)板是否損壞(huai)。接線盒(he)內的電(dian)路(lu)板是由接線端(duan)子(zi)盒(he)和幾組多(duo)(duo)圈(quan)(quan)電(dian)阻(zu)(zu)組成。接線端(duan)子(zi)長(chang)期使用可致(zhi)氧(yang)(yang)化(hua)銹蝕，接頭處氧(yang)(yang)化(hua)銹蝕部(bu)分脫落，導(dao)致(zhi)壓線松動，從而使儀表(biao)數字跳變(bian)。此(ci)時，可用砂(sha)紙或(huo)銼(cuo)刀摩擦掉其接觸面，重(zhong)新連(lian)接牢固，故(gu)障現(xian)象排(pai)除。多(duo)(duo)圈(quan)(quan)電(dian)阻(zu)(zu)長(chang)期使用也可導(dao)致(zhi)內部(bu)金屬表(biao)面被氧(yang)(yang)化(hua)，使得數字不穩、跳變(bian)，此(ci)時用更換相同阻(zu)(zu)值(zhi)的多(duo)(duo)圈(quan)(quan)電(dian)阻(zu)(zu)即可排(pai)除故(gu)障
