長興便攜式汽車衡*九亭稱重模塊*濱湖地磅檢修(xiu)流(liu)程：

檢查(cha)信號線(xian)(xian)(xian)是(shi)(shi)否斷(duan)裂，主線(xian)(xian)(xian)與儀(yi)表(biao)接頭焊(han)點是(shi)(shi)否脫落 ，接線(xian)(xian)(xian)盒里面里接線(xian)(xian)(xian)是(shi)(shi)否良好等(deng)等(deng)，這(zhe)(zhe)些(xie)(xie)都可能導致這(zhe)(zhe)個癥狀的發生。有(you)些(xie)(xie)秤體至儀(yi)表(biao)之間(jian)距(ju)離過大，其(qi)間(jian)主線(xian)(xian)(xian)有(you)外(wai)露(lu)部分，有(you)可能被人為破壞或老鼠啃咬，金屬屏蔽失去作用或連(lian)接處不牢(lao)，造成(cheng)數字(zi)跳變。用萬用表(biao)電阻(zu)檔(dang)測量(liang)該主線(xian)(xian)(xian)，以確(que)保每(mei)一股都是(shi)(shi)獨的通道(dao)，并且(qie)連(lian)線(xian)(xian)(xian)牢(lao)固(gu)，否則更換(huan)主線(xian)(xian)(xian)。其(qi)重(zhong)點是(shi)(shi)，一定要仔(zi)細確(que)認接線(xian)(xian)(xian)是(shi)(shi)否有(you)問題。如(ru)若接線(xian)(xian)(xian)是(shi)(shi)好的，那么再請檢查(cha)儀(yi)表(biao)是(shi)(shi)否正常，必要時可開封檢查(cha)儀(yi)表(biao)內部連(lian)接線(xian)(xian)(xian)是(shi)(shi)否正常。

檢查接(jie)(jie)線(xian)盒(he)(he)內(nei)電(dian)(dian)路(lu)板是(shi)否損壞。接(jie)(jie)線(xian)盒(he)(he)內(nei)的電(dian)(dian)路(lu)板是(shi)由(you)接(jie)(jie)線(xian)端子盒(he)(he)和幾組(zu)多圈電(dian)(dian)阻組(zu)成(cheng)。接(jie)(jie)線(xian)端子長期使(shi)用(yong)可(ke)(ke)(ke)致(zhi)氧化銹(xiu)蝕，接(jie)(jie)頭處氧化銹(xiu)蝕部(bu)分脫(tuo)落，導(dao)致(zhi)壓(ya)線(xian)松(song)動，從而(er)使(shi)儀表數字跳變。此時，可(ke)(ke)(ke)用(yong)砂紙或銼刀摩擦掉其(qi)接(jie)(jie)觸(chu)面，重(zhong)新連接(jie)(jie)牢固，故障現象排除(chu)。多圈電(dian)(dian)阻長期使(shi)用(yong)也可(ke)(ke)(ke)導(dao)致(zhi)內(nei)部(bu)金屬表面被(bei)氧化，使(shi)得數字不穩(wen)、跳變，此時用(yong)更換相同阻值的多圈電(dian)(dian)阻即(ji)可(ke)(ke)(ke)排除(chu)故障
