維修：

1、稱量不(bu)準確(que)的故(gu)障(zhang)分析(xi)觀測內碼值是否(fou)(fou)穩定，傳感器各部位是否(fou)(fou)有(you)摩擦現(xian)象，穩壓電源(yuan)是否(fou)(fou)穩定，運放電路(lu)是否(fou)(fou)正常，使用砝碼測試秤盤四腳秤量是否(fou)(fou)平均。依照說明書(shu)指示，進一步做儀(yi)表局部分析(xi)或重量校正。

2、稱重物(wu)移除后(hou)無法回到零點(dian)的故障(zhang)分(fen)析檢查傳感(gan)器輸出(chu)信號值是否于標(biao)準內(A/D的總放大碼/使用內碼范圍/底碼范圍)，如果信號值未在(zai)標(biao)準內，調節傳感(gan)器可調電(dian)阻，將信號值調到標(biao)準內，如無法補償請檢查傳感(gan)器是否有問題(ti)，在(zai)保證(zheng)傳感(gan)器輸出(chu)正(zheng)常(秤體穩定)情況下(xia)，鎖(suo)定儀表故障(zhang)，一(yi)般是放大電(dian)路及A/D轉換電(dian)路發生(sheng)問題(ti)，再依據電(dian)路原(yuan)理逐一(yi)判(pan)斷測試分(fen)析，以終解決問題(ti)。

3、無法(fa)開(kai)機的(de)故障(zhang)先確定非保險(xian)絲、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)關、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源線及(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)切(qie)換(huan)開(kai)關的(de)問題(ti)所(suo)造成，檢(jian)查(cha)(cha)(cha)變(bian)壓(ya)(ya)(ya)器(qi)有無交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)輸(shu)入及(ji)交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)輸(shu)出。如果(guo)儀表帶(dai)有電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)取下再以(yi)AC電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源開(kai)機，以(yi)了解是(shi)否為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)不(bu)足所(suo)造成。其次再檢(jian)測整流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)、穩(wen)壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)以(yi)及(ji)顯(xian)示(shi)驅動電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是(shi)否出現異常，如果(guo)這些都沒問題(ti)檢(jian)查(cha)(cha)(cha)處理器(qi)及(ji)附屬電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是(shi)否燒壞。4、顯(xian)示(shi)亂碼將(jiang)原來的(de)顯(xian)示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)拆下，換(huan)一個正常的(de)顯(xian)示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)看是(shi)否正常。如果(guo)顯(xian)示(shi)正常說明顯(xian)示(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)出現問題(ti)，如果(guo)不(bu)正常，應檢(jian)查(cha)(cha)(cha)驅動電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)是(shi)否有故障(zhang)，后檢(jian)查(cha)(cha)(cha)處理器(qi)顯(xian)示(shi)輸(shu)出的(de)引腳是(shi)否在(zai)合理的(de)輸(shu)出范圍。

5、無(wu)法稱(cheng)到滿(man)載和無(wu)法回零(ling)的情況差不(bu)多(duo)，多(duo)數可能由于(yu)小信(xin)號輸(shu)入范圍發生了改變。按照無(wu)法回零(ling)的方法檢(jian)測，如果(guo)找(zhao)不(bu)出(chu)問題(ti)，就先檢(jian)測供電(dian)電(dian)源、A/D電(dian)路是否正(zheng)常，再檢(jian)測傳(chuan)感器輸(shu)出(chu)。
