表能(neng)開機，能(neng)自檢，但(dan)不能(neng)稱重

檢修流程：

檢查(cha)信號線(xian)(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)斷(duan)裂，主線(xian)(xian)(xian)(xian)(xian)與(yu)儀(yi)(yi)表(biao)接頭焊點是(shi)(shi)否(fou)(fou)脫落 ，接線(xian)(xian)(xian)(xian)(xian)盒里面里接線(xian)(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)良好(hao)等(deng)等(deng)，這些(xie)都(dou)可(ke)能導致這個癥(zheng)狀(zhuang)的(de)發生。有(you)(you)些(xie)秤體至儀(yi)(yi)表(biao)之間距離過大(da)，其間主線(xian)(xian)(xian)(xian)(xian)有(you)(you)外露部分(fen)，有(you)(you)可(ke)能被人為破壞或老(lao)鼠啃(ken)咬，金屬屏蔽(bi)失去作(zuo)用(yong)或連接處不(bu)牢，造成數字跳變(bian)。用(yong)萬用(yong)表(biao)電(dian)阻(zu)檔測量(liang)該(gai)主線(xian)(xian)(xian)(xian)(xian)，以確保每一(yi)股都(dou)是(shi)(shi)獨的(de)通道，并且連線(xian)(xian)(xian)(xian)(xian)牢固，否(fou)(fou)則更換(huan)主線(xian)(xian)(xian)(xian)(xian)。其重點是(shi)(shi)，一(yi)定(ding)要(yao)仔(zi)細確認接線(xian)(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)有(you)(you)問題。如若接線(xian)(xian)(xian)(xian)(xian)是(shi)(shi)好(hao)的(de)，那么再(zai)請檢查(cha)儀(yi)(yi)表(biao)是(shi)(shi)否(fou)(fou)正常(chang)，必要(yao)時可(ke)開封檢查(cha)儀(yi)(yi)表(biao)內部連接線(xian)(xian)(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)正常(chang)。

檢查接線盒內電(dian)路板是否損壞。接線盒內的電(dian)路板是由接線端子盒和(he)幾(ji)組(zu)多(duo)圈(quan)電(dian)阻(zu)(zu)組(zu)成。接線端子長期(qi)使(shi)用可(ke)致(zhi)(zhi)氧化銹蝕，接頭(tou)處氧化銹蝕部(bu)分脫落(luo)，導致(zhi)(zhi)壓線松動，從而使(shi)儀表數字跳變。此時(shi)，可(ke)用砂(sha)紙或銼刀摩(mo)擦(ca)掉其接觸面，重(zhong)新連接牢(lao)固，故(gu)障現象排除(chu)。多(duo)圈(quan)電(dian)阻(zu)(zu)長期(qi)使(shi)用也(ye)可(ke)導致(zhi)(zhi)內部(bu)金(jin)屬表面被氧化，使(shi)得數字不穩、跳變，此時(shi)用更換相同(tong)阻(zu)(zu)值的多(duo)圈(quan)電(dian)阻(zu)(zu)即可(ke)排除(chu)故(gu)障。

維修故障解決方案:

1.儀表歸零的故(gu)障類型和調(diao)整(zheng)技術

1）基(ji)礎(chu)不(bu)牢(lao)，影(ying)響儀表(biao)歸(gui)(gui)零。汽車衡儀表(biao)不(bu)歸(gui)(gui)零，一(yi)方面是(shi)基(ji)礎(chu)不(bu)平(ping)；另一(yi)方面是(shi)設備放置不(bu)牢(lao)固。解決(jue)這兩個問題，就能(neng)確保儀表(biao)歸(gui)(gui)零。

2）地(di)線接(jie)觸不良。汽(qi)車衡度很高(gao)，其通電(dian)線路的電(dian)阻必須小于4Ω，接(jie)地(di)不良也會引(yin)起儀表不歸(gui)零，維修(xiu)技術就是修(xiu)整接(jie)地(di)樁。

3）限(xian)位(wei)不當造(zao)成(cheng)儀(yi)表不歸(gui)零。秤體橫、縱(zong)向限(xian)位(wei)裝置固定后，因為熱脹冷縮，沒(mei)有及(ji)時調整限(xian)位(wei)螺栓，秤體有時被側向頂死，造(zao)成(cheng)儀(yi)表不歸(gui)零。排除技術就是根(gen)據夏脹冬縮及(ji)時調整限(xian)位(wei)。

4）損壞傳感器，造成儀(yi)表不歸(gui)零(ling)(ling)。損壞傳感器是儀(yi)表不歸(gui)零(ling)(ling)常(chang)見的主要原因，維修(xiu)技術就是更換傳感器。

5）保(bao)養不到位，也影響儀表(biao)。汽車衡一般(ban)都安置在室外，揚塵、樹(shu)葉、車輛灑落的煤、沙、石等雜物隨時會堵塞標(biao)準(zhun)(zhun)間(jian)隙。影響儀表(biao)歸零；維修方(fang)法就是(shi)確保(bao)高標(biao)準(zhun)(zhun)日(ri)常的維護。

2數字閃爍(shuo)提示(shi)可(ke)能(neng)出現的故障及維修技術

有(you)三(san)種故障時(shi)，可能引起儀表(biao)數(shu)字(zi)閃爍。一是儀表(biao)有(you)問題或(huo)供電(dian)(dian)(dian)系統不(bu)穩定(ding)；二是傳(chuan)感器的插頭接(jie)觸不(bu)良(liang)或(huo)者接(jie)線(xian)盒(he)受潮；三(san)是接(jie)線(xian)電(dian)(dian)(dian)路接(jie)觸不(bu)良(liang)。維修技術(shu)就是更換儀表(biao)，檢(jian)查電(dian)(dian)(dian)源，梳理電(dian)(dian)(dian)路，晾干或(huo)用吹風機吹干接(jie)線(xian)盒(he)。

3不顯(xian)示(shi)(shi)、循(xun)環顯(xian)示(shi)(shi)提示(shi)(shi)出現(xian)的故障(zhang)及維修(xiu)技術

首先(xian)是(shi)儀表故障；其次是(shi)傳感器問題；第(di)三(san)是(shi)供電(dian)線(xian)路接觸不良。引起這(zhe)類(lei)故障故障一般是(shi)綜(zong)合性(xing)的問題，因此(ci)，要用萬(wan)能表對線(xian)路、原件逐一檢查(cha)、檢測(ce)。維修技(ji)術就是(shi)更(geng)換元件，加(jia)固線(xian)路接頭等。
