虎丘便攜式汽車衡*獅山稱重模塊檢修流程：

檢(jian)查(cha)信(xin)號線(xian)(xian)是(shi)(shi)否(fou)斷裂(lie)，主線(xian)(xian)與儀表(biao)接(jie)頭焊點是(shi)(shi)否(fou)脫落 ，接(jie)線(xian)(xian)盒里面里接(jie)線(xian)(xian)是(shi)(shi)否(fou)良(liang)好等(deng)等(deng)，這些都(dou)可能導致這個癥狀的(de)發(fa)生。有些秤(cheng)體至儀表(biao)之間距離過大，其間主線(xian)(xian)有外露部分(fen)，有可能被人為(wei)破壞或老鼠(shu)啃(ken)咬，金屬屏(ping)蔽失去作用(yong)或連(lian)接(jie)處不牢，造成數字跳(tiao)變。用(yong)萬(wan)用(yong)表(biao)電阻檔測量該主線(xian)(xian)，以確保每一股都(dou)是(shi)(shi)獨的(de)通(tong)道，并且(qie)連(lian)線(xian)(xian)牢固，否(fou)則更(geng)換主線(xian)(xian)。其重點是(shi)(shi)，一定要(yao)仔(zi)細確認接(jie)線(xian)(xian)是(shi)(shi)否(fou)有問題。如若接(jie)線(xian)(xian)是(shi)(shi)好的(de)，那么(me)再請檢(jian)查(cha)儀表(biao)是(shi)(shi)否(fou)正常，必要(yao)時可開封檢(jian)查(cha)儀表(biao)內部連(lian)接(jie)線(xian)(xian)是(shi)(shi)否(fou)正常。

檢查(cha)接(jie)(jie)線(xian)盒(he)內電(dian)(dian)路板(ban)是否損壞。接(jie)(jie)線(xian)盒(he)內的(de)(de)電(dian)(dian)路板(ban)是由接(jie)(jie)線(xian)端(duan)子盒(he)和幾(ji)組多圈(quan)電(dian)(dian)阻組成。接(jie)(jie)線(xian)端(duan)子長期使(shi)用可(ke)致氧(yang)化(hua)銹(xiu)蝕，接(jie)(jie)頭處氧(yang)化(hua)銹(xiu)蝕部(bu)分(fen)脫(tuo)落，導致壓線(xian)松動，從(cong)而使(shi)儀表數(shu)字跳(tiao)變。此(ci)時(shi)，可(ke)用砂紙(zhi)或銼刀摩擦掉其接(jie)(jie)觸面，重(zhong)新(xin)連接(jie)(jie)牢固(gu)，故(gu)障現象排除。多圈(quan)電(dian)(dian)阻長期使(shi)用也可(ke)導致內部(bu)金屬表面被(bei)氧(yang)化(hua)，使(shi)得數(shu)字不穩、跳(tiao)變，此(ci)時(shi)用更換相同阻值的(de)(de)多圈(quan)電(dian)(dian)阻即可(ke)排除故(gu)障
