檢修流程：

檢(jian)(jian)查(cha)信號線(xian)(xian)(xian)是(shi)(shi)(shi)否斷裂(lie)，主(zhu)線(xian)(xian)(xian)與儀(yi)表接(jie)頭(tou)焊(han)點是(shi)(shi)(shi)否脫落 ，接(jie)線(xian)(xian)(xian)盒里面(mian)里接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否良(liang)好(hao)等等，這些(xie)都可能導致(zhi)這個癥狀(zhuang)的(de)發生(sheng)。有些(xie)秤(cheng)體至(zhi)儀(yi)表之間(jian)距(ju)離過大(da)，其(qi)(qi)間(jian)主(zhu)線(xian)(xian)(xian)有外露部分(fen)，有可能被人為破壞或老(lao)鼠(shu)啃咬，金屬屏蔽(bi)失去作用(yong)或連(lian)接(jie)處(chu)不(bu)牢，造(zao)成數字跳變。用(yong)萬用(yong)表電阻(zu)檔測量該主(zhu)線(xian)(xian)(xian)，以(yi)確保每(mei)一股都是(shi)(shi)(shi)獨的(de)通道，并且(qie)連(lian)線(xian)(xian)(xian)牢固，否則更(geng)換主(zhu)線(xian)(xian)(xian)。其(qi)(qi)重點是(shi)(shi)(shi)，一定要(yao)(yao)仔細確認接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否有問題(ti)。如若接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)好(hao)的(de)，那么再請檢(jian)(jian)查(cha)儀(yi)表是(shi)(shi)(shi)否正常，必要(yao)(yao)時可開封(feng)檢(jian)(jian)查(cha)儀(yi)表內部連(lian)接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否正常。

檢查接(jie)(jie)線(xian)盒(he)內(nei)電(dian)路板是(shi)否損壞(huai)。接(jie)(jie)線(xian)盒(he)內(nei)的(de)電(dian)路板是(shi)由接(jie)(jie)線(xian)端子盒(he)和幾組多(duo)圈電(dian)阻組成。接(jie)(jie)線(xian)端子長期(qi)使(shi)用(yong)可(ke)致(zhi)(zhi)氧(yang)化(hua)銹(xiu)(xiu)蝕，接(jie)(jie)頭處氧(yang)化(hua)銹(xiu)(xiu)蝕部分脫(tuo)落，導(dao)致(zhi)(zhi)壓線(xian)松動，從(cong)而使(shi)儀表(biao)數(shu)字(zi)跳變。此(ci)時(shi)，可(ke)用(yong)砂(sha)紙(zhi)或銼(cuo)刀摩擦掉(diao)其(qi)接(jie)(jie)觸(chu)面，重新連接(jie)(jie)牢(lao)固，故障(zhang)現象排除。多(duo)圈電(dian)阻長期(qi)使(shi)用(yong)也可(ke)導(dao)致(zhi)(zhi)內(nei)部金(jin)屬表(biao)面被氧(yang)化(hua)，使(shi)得數(shu)字(zi)不(bu)穩、跳變，此(ci)時(shi)用(yong)更換相同阻值的(de)多(duo)圈電(dian)阻即可(ke)排除故障(zhang)
