檢修流程：

檢(jian)查信(xin)號線(xian)(xian)(xian)(xian)是(shi)否(fou)斷裂，主線(xian)(xian)(xian)(xian)與儀(yi)表(biao)(biao)接(jie)(jie)頭焊點是(shi)否(fou)脫落 ，接(jie)(jie)線(xian)(xian)(xian)(xian)盒里(li)面里(li)接(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)否(fou)良(liang)好等(deng)等(deng)，這些(xie)都可能(neng)導致這個癥狀的(de)(de)發(fa)生(sheng)。有些(xie)秤體至(zhi)儀(yi)表(biao)(biao)之間距離過大，其間主線(xian)(xian)(xian)(xian)有外(wai)露(lu)部(bu)分(fen)，有可能(neng)被(bei)人為破(po)壞或老(lao)鼠啃咬(yao)，金屬屏蔽失去作(zuo)用或連(lian)接(jie)(jie)處不牢，造成數字跳變。用萬(wan)用表(biao)(biao)電阻(zu)檔測量該主線(xian)(xian)(xian)(xian)，以確(que)保每一股都是(shi)獨(du)的(de)(de)通道，并且連(lian)線(xian)(xian)(xian)(xian)牢固(gu)，否(fou)則更換(huan)主線(xian)(xian)(xian)(xian)。其重點是(shi)，一定要仔細(xi)確(que)認(ren)接(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)否(fou)有問(wen)題。如若接(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)好的(de)(de)，那么(me)再(zai)請檢(jian)查儀(yi)表(biao)(biao)是(shi)否(fou)正常，必(bi)要時可開封檢(jian)查儀(yi)表(biao)(biao)內(nei)部(bu)連(lian)接(jie)(jie)線(xian)(xian)(xian)(xian)是(shi)否(fou)正常。

檢查(cha)接線(xian)盒(he)內(nei)電(dian)路板是否(fou)損壞。接線(xian)盒(he)內(nei)的(de)電(dian)路板是由接線(xian)端(duan)子(zi)盒(he)和幾組多(duo)圈電(dian)阻組成。接線(xian)端(duan)子(zi)長(chang)期使(shi)(shi)用可(ke)致氧(yang)化(hua)銹(xiu)蝕，接頭(tou)處氧(yang)化(hua)銹(xiu)蝕部分脫落，導致壓線(xian)松(song)動，從而使(shi)(shi)儀表數字跳變。此(ci)時，可(ke)用砂紙或銼刀摩擦掉其接觸面(mian)，重新連接牢固，故障現象排(pai)除(chu)。多(duo)圈電(dian)阻長(chang)期使(shi)(shi)用也(ye)可(ke)導致內(nei)部金(jin)屬表面(mian)被氧(yang)化(hua)，使(shi)(shi)得數字不穩(wen)、跳變，此(ci)時用更換(huan)相同阻值的(de)多(duo)圈電(dian)阻即(ji)可(ke)排(pai)除(chu)故障
