檢修流程：

檢查信號(hao)線(xian)(xian)(xian)是(shi)(shi)(shi)否(fou)(fou)斷裂，主(zhu)線(xian)(xian)(xian)與(yu)儀(yi)(yi)(yi)表接(jie)頭(tou)焊點(dian)是(shi)(shi)(shi)否(fou)(fou)脫落(luo) ，接(jie)線(xian)(xian)(xian)盒里(li)面里(li)接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否(fou)(fou)良好(hao)等(deng)(deng)等(deng)(deng)，這(zhe)些都(dou)可能(neng)導致這(zhe)個癥狀的發生。有(you)些秤(cheng)體(ti)至儀(yi)(yi)(yi)表之間(jian)(jian)距離過大(da)，其間(jian)(jian)主(zhu)線(xian)(xian)(xian)有(you)外露部(bu)分(fen)，有(you)可能(neng)被人為破壞(huai)或(huo)老鼠啃咬，金(jin)屬屏蔽失去作用或(huo)連(lian)接(jie)處不牢(lao)，造(zao)成(cheng)數(shu)字(zi)跳(tiao)變。用萬(wan)用表電(dian)阻檔測量該主(zhu)線(xian)(xian)(xian)，以確保每一(yi)股都(dou)是(shi)(shi)(shi)獨的通道，并且連(lian)線(xian)(xian)(xian)牢(lao)固，否(fou)(fou)則更換主(zhu)線(xian)(xian)(xian)。其重(zhong)點(dian)是(shi)(shi)(shi)，一(yi)定(ding)要仔(zi)細確認(ren)接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否(fou)(fou)有(you)問題。如若接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)好(hao)的，那(nei)么再請檢查儀(yi)(yi)(yi)表是(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)常，必要時可開封檢查儀(yi)(yi)(yi)表內部(bu)連(lian)接(jie)線(xian)(xian)(xian)是(shi)(shi)(shi)否(fou)(fou)正(zheng)(zheng)常。

檢查接(jie)線盒(he)內(nei)電路板是(shi)否損(sun)壞。接(jie)線盒(he)內(nei)的電路板是(shi)由(you)接(jie)線端(duan)子(zi)(zi)盒(he)和幾組多(duo)(duo)圈電阻(zu)(zu)組成。接(jie)線端(duan)子(zi)(zi)長期使用可(ke)致(zhi)氧(yang)化(hua)銹(xiu)蝕(shi)，接(jie)頭處氧(yang)化(hua)銹(xiu)蝕(shi)部(bu)分脫(tuo)落，導(dao)致(zhi)壓線松動，從而使儀表數字跳變。此(ci)(ci)時，可(ke)用砂紙或銼(cuo)刀摩擦掉其接(jie)觸(chu)面，重新(xin)連接(jie)牢固(gu)，故障(zhang)現象排除。多(duo)(duo)圈電阻(zu)(zu)長期使用也(ye)可(ke)導(dao)致(zhi)內(nei)部(bu)金(jin)屬(shu)表面被氧(yang)化(hua)，使得數字不穩、跳變，此(ci)(ci)時用更換相同阻(zu)(zu)值的多(duo)(duo)圈電阻(zu)(zu)即可(ke)排除故障(zhang)
