表(biao)能開機，能自(zi)檢(jian)，但不能稱重

檢修流程：

檢查(cha)信(xin)號線(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)(fou)斷裂，主線(xian)(xian)(xian)與儀(yi)表(biao)接(jie)(jie)(jie)(jie)頭(tou)焊點是(shi)(shi)否(fou)(fou)(fou)脫落 ，接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)盒里面里接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)(fou)良好(hao)等(deng)等(deng)，這些(xie)都(dou)可能導致這個癥(zheng)狀(zhuang)的(de)(de)發生。有些(xie)秤體(ti)至儀(yi)表(biao)之間(jian)距離(li)過大，其間(jian)主線(xian)(xian)(xian)有外露部(bu)分，有可能被(bei)人為破(po)壞或(huo)老鼠啃咬，金屬屏蔽(bi)失(shi)去(qu)作用或(huo)連接(jie)(jie)(jie)(jie)處不牢，造成數字跳變(bian)。用萬用表(biao)電阻(zu)檔測(ce)量該主線(xian)(xian)(xian)，以(yi)確(que)保每一(yi)(yi)股都(dou)是(shi)(shi)獨的(de)(de)通道，并且連線(xian)(xian)(xian)牢固，否(fou)(fou)(fou)則更換(huan)主線(xian)(xian)(xian)。其重點是(shi)(shi)，一(yi)(yi)定要仔(zi)細確(que)認(ren)接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)(fou)有問題(ti)。如若(ruo)接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)是(shi)(shi)好(hao)的(de)(de)，那么再請檢查(cha)儀(yi)表(biao)是(shi)(shi)否(fou)(fou)(fou)正常，必要時可開封檢查(cha)儀(yi)表(biao)內部(bu)連接(jie)(jie)(jie)(jie)線(xian)(xian)(xian)是(shi)(shi)否(fou)(fou)(fou)正常。

檢查接線(xian)(xian)盒(he)內電路板是(shi)否損(sun)壞。接線(xian)(xian)盒(he)內的(de)電路板是(shi)由接線(xian)(xian)端(duan)子盒(he)和幾組多圈(quan)電阻(zu)(zu)組成(cheng)。接線(xian)(xian)端(duan)子長期(qi)使用(yong)可(ke)(ke)致(zhi)氧化銹(xiu)蝕(shi)，接頭(tou)處(chu)氧化銹(xiu)蝕(shi)部分脫落，導(dao)(dao)致(zhi)壓(ya)線(xian)(xian)松動，從而(er)使儀表數(shu)字跳(tiao)變(bian)(bian)。此時(shi)，可(ke)(ke)用(yong)砂紙或銼刀(dao)摩(mo)擦掉其接觸面，重新連接牢(lao)固(gu)，故障(zhang)現(xian)象排(pai)除。多圈(quan)電阻(zu)(zu)長期(qi)使用(yong)也可(ke)(ke)導(dao)(dao)致(zhi)內部金屬(shu)表面被氧化，使得數(shu)字不穩、跳(tiao)變(bian)(bian)，此時(shi)用(yong)更(geng)換相同阻(zu)(zu)值的(de)多圈(quan)電阻(zu)(zu)即(ji)可(ke)(ke)排(pai)除故障(zhang)。

維修故障解決方案:

1.儀(yi)表歸零(ling)的故障類(lei)型(xing)和調整(zheng)技術

1）基礎(chu)不(bu)牢(lao)(lao)，影響儀表歸(gui)零。汽車衡儀表不(bu)歸(gui)零，一方面是基礎(chu)不(bu)平(ping)；另一方面是設備放(fang)置不(bu)牢(lao)(lao)固。解(jie)決(jue)這兩個(ge)問題，就能確(que)保儀表歸(gui)零。

2）地線接觸不(bu)良。汽車(che)衡(heng)度很高，其通電線路(lu)的電阻(zu)必須小(xiao)于4Ω，接地不(bu)良也會引起儀表不(bu)歸零，維(wei)修(xiu)技術就是修(xiu)整接地樁。

3）限位(wei)不當(dang)造成儀表不歸(gui)零。秤體(ti)橫、縱向限位(wei)裝置固定(ding)后，因為熱(re)脹冷縮，沒有(you)及(ji)(ji)時(shi)(shi)調整限位(wei)螺栓，秤體(ti)有(you)時(shi)(shi)被側向頂死，造成儀表不歸(gui)零。排(pai)除技術就是根據夏脹冬(dong)縮及(ji)(ji)時(shi)(shi)調整限位(wei)。

4）損(sun)壞傳感(gan)器，造成儀表不(bu)歸零。損(sun)壞傳感(gan)器是儀表不(bu)歸零常見的主(zhu)要(yao)原因，維修(xiu)技術就是更換(huan)傳感(gan)器。

5）保(bao)養不到位，也(ye)影響儀表。汽車(che)衡(heng)一般都安置在室外，揚塵、樹葉、車(che)輛灑(sa)落的煤、沙、石等雜物(wu)隨時會堵塞標準(zhun)間隙(xi)。影響儀表歸零；維(wei)修方法就是確保(bao)高(gao)標準(zhun)日常的維(wei)護。

2數字閃(shan)爍提示(shi)可能出現的故障及維(wei)修技(ji)術

有(you)三種故障(zhang)時，可能引起儀(yi)(yi)表(biao)數字閃爍。一是(shi)(shi)儀(yi)(yi)表(biao)有(you)問(wen)題或(huo)供電(dian)系統不(bu)穩定；二(er)是(shi)(shi)傳感器的插頭(tou)接(jie)觸不(bu)良或(huo)者接(jie)線(xian)盒受潮；三是(shi)(shi)接(jie)線(xian)電(dian)路接(jie)觸不(bu)良。維修技術就是(shi)(shi)更換(huan)儀(yi)(yi)表(biao)，檢查電(dian)源，梳理電(dian)路，晾干或(huo)用(yong)吹風機吹干接(jie)線(xian)盒。

3不顯(xian)示(shi)、循環顯(xian)示(shi)提示(shi)出現(xian)的故障及(ji)維(wei)修技術

首先是(shi)儀表(biao)故障(zhang)；其次(ci)是(shi)傳(chuan)感器(qi)問(wen)題；第三是(shi)供(gong)電線(xian)路(lu)接(jie)觸不良。引(yin)起這類故障(zhang)故障(zhang)一(yi)(yi)般是(shi)綜合性的問(wen)題，因此，要用萬能表(biao)對線(xian)路(lu)、原件逐一(yi)(yi)檢(jian)查、檢(jian)測。維修技術(shu)就是(shi)更換元(yuan)件，加(jia)固線(xian)路(lu)接(jie)頭等。
