維修：

1、稱(cheng)量(liang)(liang)不準確的(de)故障分(fen)析(xi)觀測內碼值是否(fou)(fou)穩定，傳感器各部位是否(fou)(fou)有摩擦現象，穩壓(ya)電源是否(fou)(fou)穩定，運放電路是否(fou)(fou)正常，使(shi)用砝碼測試秤(cheng)盤四腳(jiao)秤(cheng)量(liang)(liang)是否(fou)(fou)平均(jun)。依照說明書指示，進一步(bu)做(zuo)儀表局部分(fen)析(xi)或重量(liang)(liang)校正。

2、稱(cheng)重物移除后無法回(hui)到(dao)零點的(de)故(gu)障(zhang)分析檢查(cha)傳感器輸出(chu)信(xin)號值(zhi)是否于標(biao)準內(A/D的(de)總(zong)放大碼(ma)/使用內碼(ma)范(fan)圍/底碼(ma)范(fan)圍)，如(ru)果信(xin)號值(zhi)未在標(biao)準內，調(diao)節傳感器可調(diao)電阻，將信(xin)號值(zhi)調(diao)到(dao)標(biao)準內，如(ru)無法補償請(qing)檢查(cha)傳感器是否有問題，在保證傳感器輸出(chu)正常(秤體穩(wen)定)情況下(xia)，鎖定儀表故(gu)障(zhang)，一般是放大電路及A/D轉換電路發生問題，再依據電路原理逐一判斷測試分析，以終解(jie)決問題。

3、無法開(kai)機(ji)的故(gu)障(zhang)先確(que)定非保險(xian)絲、電(dian)(dian)源開(kai)關(guan)、電(dian)(dian)源線及電(dian)(dian)壓切換(huan)(huan)開(kai)關(guan)的問(wen)題(ti)所(suo)造成，檢(jian)查變壓器(qi)有無交流(liu)電(dian)(dian)壓輸入及交流(liu)電(dian)(dian)輸出。如果(guo)儀表帶(dai)有電(dian)(dian)池(chi)(chi)將電(dian)(dian)池(chi)(chi)取下再以AC電(dian)(dian)源開(kai)機(ji)，以了解是(shi)否(fou)為電(dian)(dian)池(chi)(chi)電(dian)(dian)壓不足(zu)所(suo)造成。其次(ci)再檢(jian)測整流(liu)電(dian)(dian)路(lu)(lu)(lu)、穩壓電(dian)(dian)路(lu)(lu)(lu)以及顯(xian)(xian)示(shi)驅(qu)動(dong)電(dian)(dian)路(lu)(lu)(lu)是(shi)否(fou)出現異常(chang)(chang)(chang)，如果(guo)這些都沒問(wen)題(ti)檢(jian)查處理器(qi)及附(fu)屬電(dian)(dian)路(lu)(lu)(lu)是(shi)否(fou)燒壞。4、顯(xian)(xian)示(shi)亂碼將原來的顯(xian)(xian)示(shi)電(dian)(dian)路(lu)(lu)(lu)拆下，換(huan)(huan)一個(ge)正(zheng)常(chang)(chang)(chang)的顯(xian)(xian)示(shi)電(dian)(dian)路(lu)(lu)(lu)看(kan)是(shi)否(fou)正(zheng)常(chang)(chang)(chang)。如果(guo)顯(xian)(xian)示(shi)正(zheng)常(chang)(chang)(chang)說(shuo)明(ming)顯(xian)(xian)示(shi)電(dian)(dian)路(lu)(lu)(lu)出現問(wen)題(ti)，如果(guo)不正(zheng)常(chang)(chang)(chang)，應檢(jian)查驅(qu)動(dong)電(dian)(dian)路(lu)(lu)(lu)是(shi)否(fou)有故(gu)障(zhang)，后檢(jian)查處理器(qi)顯(xian)(xian)示(shi)輸出的引腳是(shi)否(fou)在合理的輸出范圍。

5、無(wu)法稱到滿(man)載和無(wu)法回(hui)零(ling)的情(qing)況(kuang)差不多，多數可能由于小(xiao)信號輸(shu)(shu)入范圍發生(sheng)了改變。按照無(wu)法回(hui)零(ling)的方法檢(jian)(jian)測(ce)，如果找不出問題，就(jiu)先檢(jian)(jian)測(ce)供電電源、A/D電路是否正常，再(zai)檢(jian)(jian)測(ce)傳感器輸(shu)(shu)出。
