防(fang)爆電(dian)子(zi)(zi)(zi)臺(tai)秤防(fang)爆電(dian)子(zi)(zi)(zi)桌(zhuo)秤隔爆電(dian)子(zi)(zi)(zi)臺(tai)秤防(fang)腐(fu)蝕電(dian)子(zi)(zi)(zi)秤維(wei)修:
1、開機無(wu)任何顯(xian)示(shi)、聲音：從電(dian)路(lu)上分析(xi)“無(wu)顯(xian)示(shi)”是(shi)顯(xian)示(shi)電(dian)路(lu)的(de)故障，沒有聲音是(shi)蜂鳴(ming)電(dian)路(lu)上的(de)故障。這2個故障同時出(chu)現的(de)概率很(hen)低(di)。所以一(yi)般故障出(chu)現在供電(dian)電(dian)路(lu)上。
2、稱重量(liang)不(bu)準：觀測傳感(gan)器各部位是(shi)否有(you)摩擦現象，穩(wen)壓電源(yuan)是(shi)否穩(wen)定，運放(fang)電路是(shi)否正常。A/D電路的線路板是(shi)否有(you)異(yi)物(wu)。
3、顯示不良(liang)：開機觀察正(zheng)常的(de)LCD上(shang)是否有不良(liang)情況(kuang)，如果沒(mei)有的(de)話可斷定為LCD不良(liang)；檢查(cha)CPU接(jie)腳(jiao)有無氧化(hua)、冷焊或短路現象；檢查(cha)CPU與LCD之間線路有無短路。
4、電池無(wu)法蓄電：先(xian)確(que)定保(bao)險絲、電源開(kai)關、電源線的問題所(suo)造成；檢(jian)查(cha)變壓器有無(wu)AC110/220輸(shu)(shu)入及AC18V輸(shu)(shu)出(chu)；檢(jian)查(cha)機版，變壓器輸(shu)(shu)入端插PIN附件之二極體(ti)是(shi)否正常；更換蓄電池。
5、電(dian)(dian)(dian)(dian)(dian)(dian)子稱無法充電(dian)(dian)(dian)(dian)(dian)(dian)或充電(dian)(dian)(dian)(dian)(dian)(dian)指示燈不量(liang)或沒(mei)反應：請先確定電(dian)(dian)(dian)(dian)(dian)(dian)子稱的(de)110V/220V電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)切換開(kai)關是否(fou)調到與使用電(dian)(dian)(dian)(dian)(dian)(dian)源一樣的(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)，并確定充電(dian)(dian)(dian)(dian)(dian)(dian)線已牢固(gu)的(de)插(cha)在秤上(shang)的(de)充電(dian)(dian)(dian)(dian)(dian)(dian)座；檢查充電(dian)(dian)(dian)(dian)(dian)(dian)線是否(fou)有外力(li)因素而造成(cheng)斷路；檢查保險絲(si)是否(fou)不良；蓄電(dian)(dian)(dian)(dian)(dian)(dian)池不良。
6、按鍵(jian)無動作(zuo)或(huo)動作(zuo)不(bu)(bu)正(zheng)常會自(zi)動觸發：按鍵(jian)不(bu)(bu)良(liang)；按鍵(jian)插座不(bu)(bu)良(liang)。
7、電(dian)(dian)(dian)子(zi)稱(cheng)(cheng)無(wu)法秤(cheng)到滿載：電(dian)(dian)(dian)子(zi)稱(cheng)(cheng)保(bao)護(hu)螺(luo)絲未(wei)拆除(chu)；電(dian)(dian)(dian)子(zi)稱(cheng)(cheng)是否(fou)有異(yi)物滲入造成干涉或(huo)撞擊、摔傷；電(dian)(dian)(dian)子(zi)臺秤(cheng)的(de)內部程序設(she)定是否(fou)正(zheng)確。
