①、首(shou)先檢查(cha)(cha)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)是否正常(chang)（顯(xian)示器(qi)前面(mian)有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)指示燈是否指示、亮點）。 ②、再檢查(cha)(cha)220V交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)插頭(tou)是否松(song)，插座有(you)(you)沒有(you)(you)插好(hao)(hao)，電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線有(you)(you)沒有(you)(you)斷(duan)裂。 ③、儀(yi)(yi)表內(nei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)是否欠壓，造成自(zi)(zi)動關機（有(you)(you)內(nei)置電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)機種(zhong)）。 ④、然(ran)后檢查(cha)(cha)顯(xian)示器(qi)后面(mian)的交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)保(bao)險(xian)絲(si)（上面(mian)一根）是否完好(hao)(hao)（可(ke)自(zi)(zi)行(xing)修復更換(huan)通用保(bao)險(xian)絲(si)、插座、電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)線即可(ke)）。 ⑤、A9儀(yi)(yi)表：2根保(bao)險(xian)絲(si)，上面(mian)是交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)保(bao)險(xian)絲(si)，下面(mian)是直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)保(bao)險(xian)絲(si)。停(ting)電(dian)(dian)(dian)(dian)(dian)(dian)需(xu)按下儀(yi)(yi)表后紅(hong)色按鈕，就切換(huan)到直(zhi)流電(dian)(dian)(dian)(dian)(dian)(dian)工作狀態，電(dian)(dian)(dian)(dian)(dian)(dian)來自(zi)(zi)動切換(huan)交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)工作狀態 ⑥、A9+儀(yi)(yi)表：1根保(bao)險(xian)絲(si)，是交(jiao)/直(zhi)流保(bao)險(xian)絲(si)，若斷(duan)了儀(yi)(yi)表都沒顯(xian)示。

修常見(jian)故障檢修實(shi)例之二：

某公司用(yong)(yong)(yong)于一(yi)臺(tai)100噸數字(zi)式地磅，使用(yong)(yong)(yong)過(guo)程發(fa)現(xian)(xian)重(zhong)量異(yi)(yi)常(chang)，利(li)用(yong)(yong)(yong)重(zhong)車(che)對比(bi)發(fa)現(xian)(xian)45噸的重(zhong)車(che)偏(pian)差(cha)7噸多，查(cha)看(kan)(kan)段(duan)差(cha)發(fa)現(xian)(xian)3段(duan)重(zhong)量偏(pian)差(cha)大，處理過(guo)程：用(yong)(yong)(yong)8噸叉車(che)查(cha)看(kan)(kan)角(jiao)(jiao)(jiao)差(cha)，發(fa)現(xian)(xian)6只傳(chuan)感器(qi)偏(pian)差(cha)2噸多，檢查(cha)機械機構及傳(chuan)感器(qi)未見(jian)異(yi)(yi)常(chang)，更(geng)換一(yi)只新傳(chuan)感器(qi)調試，故(gu)障仍無法排除，嘗試將傳(chuan)感器(qi)地址位兌對換，發(fa)現(xian)(xian)6只仍就(jiu)存在大偏(pian)差(cha)，后在查(cha)看(kan)(kan)儀表參數中發(fa)現(xian)(xian)，角(jiao)(jiao)(jiao)差(cha)常(chang)數6號被改(gai)為0，將該系數改(gai)為1后重(zhong)新調整8點角(jiao)(jiao)(jiao)差(cha)平(ping)衡，用(yong)(yong)(yong)重(zhong)車(che)對比(bi)校正(zheng)后恢復正(zheng)常(chang)。

小(xiao)(xiao)結：儀(yi)表的任何(he)一個參(can)數都有(you)可能影(ying)響各傳(chuan)感(gan)器性能等情(qing)況，嚴禁非人(ren)員對儀(yi)表參(can)數做(zuo)任何(he)修改，另維修考慮需盡可能的全面，避(bi)免小(xiao)(xiao)故(gu)障，而處理過程(cheng)中把簡單的事情(qing)復雜化。

故(gu)(gu)障(zhang)檢修實例之三：某(mou)公司有(you)一(yi)臺80噸的(de)(de)模擬式(shi)地(di)磅，有(you)時(shi)重車開(kai)(kai)上之后(hou)就會由負(fu)超載(zai)的(de)(de)情(qing)況出(chu)現(xian)(xian)，等(deng)待(dai)重新開(kai)(kai)機之后(hou)，又會恢復到正(zheng)常的(de)(de)情(qing)況。分(fen)析：故(gu)(gu)障(zhang)出(chu)現(xian)(xian)時(shi)有(you)時(shi)無的(de)(de)情(qing)況，估計(ji)不是儀表的(de)(de)原因，對秤臺，連(lian)接(jie)件(jian)以及限(xian)位等(deng)檢查(cha)后(hou)都屬(shu)于(yu)正(zheng)常，排除了機械方面的(de)(de)問題(ti)，重新檢查(cha)一(yi)次接(jie)線(xian)板的(de)(de)所有(you)焊點，也排除了脫焊和虛焊的(de)(de)問題(ti)。后(hou)使(shi)用扯線(xian)法和替代法，發(fa)現(xian)(xian)某(mou)一(yi)個(ge)傳(chuan)感器(qi)出(chu)現(xian)(xian)了故(gu)(gu)障(zhang)，通過檢查(cha)，發(fa)現(xian)(xian)有(you)一(yi)只傳(chuan)感器(qi)的(de)(de)正(zheng)信號線(xian)被坑破(po)，有(you)時(shi)候接(jie)觸上儀表就能正(zheng)常顯示，如(ru)果斷(duan)開(kai)(kai)，那么就會出(chu)現(xian)(xian)負(fu)超載(zai)的(de)(de)問題(ti)。

處理：剪斷被咬破的傳(chuan)感器信號線(xian)，然后重新(xin)制(zhi)作一(yi)個接頭，那么地(di)磅就能夠恢復正常狀態。
