表能開機(ji)，能自檢，但不能稱重(zhong)

檢修流程：

檢查(cha)信號線(xian)是否斷裂，主線(xian)與(yu)儀(yi)表(biao)(biao)(biao)接(jie)頭焊點是否脫落 ，接(jie)線(xian)盒里面里接(jie)線(xian)是否良好(hao)等等，這些都(dou)可能(neng)導致這個(ge)癥狀的(de)發生(sheng)。有(you)些秤體至儀(yi)表(biao)(biao)(biao)之(zhi)間(jian)距離過大，其(qi)間(jian)主線(xian)有(you)外露部分，有(you)可能(neng)被人(ren)為破壞或老(lao)鼠啃咬，金屬屏蔽失去(qu)作用(yong)或連(lian)接(jie)處(chu)不牢，造成數(shu)字跳變(bian)。用(yong)萬用(yong)表(biao)(biao)(biao)電阻檔測(ce)量(liang)該主線(xian)，以確保每一股都(dou)是獨的(de)通道，并且連(lian)線(xian)牢固，否則(ze)更換主線(xian)。其(qi)重點是，一定(ding)要仔(zi)細確認接(jie)線(xian)是否有(you)問題。如若接(jie)線(xian)是好(hao)的(de)，那么再請檢查(cha)儀(yi)表(biao)(biao)(biao)是否正常(chang)，必(bi)要時可開(kai)封檢查(cha)儀(yi)表(biao)(biao)(biao)內部連(lian)接(jie)線(xian)是否正常(chang)。

檢(jian)查接(jie)(jie)(jie)(jie)線(xian)盒(he)內(nei)電路板是否(fou)損壞。接(jie)(jie)(jie)(jie)線(xian)盒(he)內(nei)的(de)電路板是由接(jie)(jie)(jie)(jie)線(xian)端子盒(he)和幾組多圈(quan)電阻(zu)組成(cheng)。接(jie)(jie)(jie)(jie)線(xian)端子長(chang)期(qi)使(shi)用(yong)可(ke)致氧化(hua)銹蝕，接(jie)(jie)(jie)(jie)頭(tou)處氧化(hua)銹蝕部(bu)分脫落，導致壓線(xian)松動，從而使(shi)儀表數字跳變。此(ci)時，可(ke)用(yong)砂紙或銼刀摩擦掉其接(jie)(jie)(jie)(jie)觸(chu)面，重新連接(jie)(jie)(jie)(jie)牢(lao)固，故障現象排除(chu)。多圈(quan)電阻(zu)長(chang)期(qi)使(shi)用(yong)也可(ke)導致內(nei)部(bu)金屬(shu)表面被氧化(hua)，使(shi)得數字不(bu)穩、跳變，此(ci)時用(yong)更換相同阻(zu)值的(de)多圈(quan)電阻(zu)即可(ke)排除(chu)故障。
