①、首先檢查電(dian)(dian)(dian)源(yuan)是否(fou)正常（顯示器前面有(you)電(dian)(dian)(dian)源(yuan)指(zhi)示燈(deng)是否(fou)指(zhi)示、亮(liang)點）。 ②、再檢查220V交(jiao)流電(dian)(dian)(dian)源(yuan)插(cha)頭是否(fou)松，插(cha)座有(you)沒(mei)有(you)插(cha)好，電(dian)(dian)(dian)源(yuan)線有(you)沒(mei)有(you)斷(duan)裂。 ③、儀表(biao)內電(dian)(dian)(dian)池是否(fou)欠壓，造成自(zi)動(dong)關機（有(you)內置(zhi)電(dian)(dian)(dian)池機種）。 ④、然(ran)后(hou)檢查顯示器后(hou)面的交(jiao)流電(dian)(dian)(dian)源(yuan)保險絲(si)(si)（上面一根(gen)）是否(fou)完好（可自(zi)行修復更換通用保險絲(si)(si)、插(cha)座、電(dian)(dian)(dian)源(yuan)線即可）。 ⑤、A9儀表(biao)：2根(gen)保險絲(si)(si)，上面是交(jiao)流電(dian)(dian)(dian)保險絲(si)(si)，下面是直流電(dian)(dian)(dian)保險絲(si)(si)。停電(dian)(dian)(dian)需按下儀表(biao)后(hou)紅(hong)色(se)按鈕(niu)，就切換到直流電(dian)(dian)(dian)工作狀態(tai)，電(dian)(dian)(dian)來自(zi)動(dong)切換交(jiao)流電(dian)(dian)(dian)工作狀態(tai) ⑥、A9+儀表(biao)：1根(gen)保險絲(si)(si)，是交(jiao)/直流保險絲(si)(si)，若斷(duan)了儀表(biao)都沒(mei)顯示。

表能開機，能自檢，但不能稱(cheng)重

檢修流程：

檢查信號線是否斷裂，主(zhu)(zhu)線與儀表(biao)(biao)接頭焊點(dian)是否脫落 ，接線盒里面里接線是否良(liang)好等等，這(zhe)些都(dou)可能導致這(zhe)個癥狀的發生。有(you)(you)些秤體(ti)至(zhi)儀表(biao)(biao)之間距離過大，其間主(zhu)(zhu)線有(you)(you)外露部分，有(you)(you)可能被(bei)人(ren)為破壞(huai)或老(lao)鼠(shu)啃咬，金屬屏(ping)蔽失(shi)去作用或連接處不(bu)牢(lao)，造成數字(zi)跳(tiao)變。用萬(wan)用表(biao)(biao)電(dian)阻檔測量該(gai)主(zhu)(zhu)線，以確保每(mei)一股都(dou)是獨的通(tong)道，并且連線牢(lao)固，否則更(geng)換主(zhu)(zhu)線。其重點(dian)是，一定要(yao)仔細確認(ren)接線是否有(you)(you)問題(ti)。如(ru)若接線是好的，那么再請檢查儀表(biao)(biao)是否正(zheng)常(chang)，必要(yao)時可開封檢查儀表(biao)(biao)內(nei)部連接線是否正(zheng)常(chang)。

檢查接線(xian)(xian)盒(he)內(nei)(nei)電路板是否損壞。接線(xian)(xian)盒(he)內(nei)(nei)的電路板是由接線(xian)(xian)端(duan)子(zi)盒(he)和幾組(zu)多圈電阻(zu)組(zu)成。接線(xian)(xian)端(duan)子(zi)長期使(shi)用(yong)可致(zhi)氧(yang)化(hua)銹蝕(shi)，接頭處氧(yang)化(hua)銹蝕(shi)部分脫落，導致(zhi)壓線(xian)(xian)松(song)動，從而使(shi)儀(yi)表數字跳變。此時，可用(yong)砂紙或銼刀(dao)摩擦掉其接觸面，重新(xin)連接牢固，故障現象排除。多圈電阻(zu)長期使(shi)用(yong)也(ye)可導致(zhi)內(nei)(nei)部金屬表面被氧(yang)化(hua)，使(shi)得(de)數字不(bu)穩、跳變，此時用(yong)更(geng)換相同阻(zu)值的多圈電阻(zu)即可排除故障。
