怎樣判(pan)(pan)(pan)別地磅(bang)傳感器(qi)(qi)是否損(sun)壞？準備(bei)好(hao)(hao)的(de)傳感器(qi)(qi)、線(xian)路(lu)(lu)板、電(dian)源、鍵盤等(deng)部(bu)件(jian)(jian)，若置疑傳感器(qi)(qi)、線(xian)路(lu)(lu)板、電(dian)源、鍵盤等(deng)某(mou)(mou)個部(bu)件(jian)(jian)損(sun)壞，用(yong)(yong)備(bei)好(hao)(hao)的(de)部(bu)件(jian)(jian)替代，然(ran)后(hou)(hou)查詢作用(yong)(yong)是否有改動，假定(ding)閃現(xian)正(zheng)常，則說明(ming)原本的(de)元件(jian)(jian)有問題。比(bi)較、替代法(fa)能快速準確地判(pan)(pan)(pan)別出(chu)缺(que)(que)(que)陷點。,3.電(dian)壓(ya)(ya)測量(liang)法(fa),通(tong)過對電(dian)路(lu)(lu)元件(jian)(jian)、芯(xin)片(pian)各個管角(jiao)的(de)作業(ye)電(dian)壓(ya)(ya)的(de)測量(liang)與正(zheng)常值進行比(bi)較，電(dian)壓(ya)(ya)改動較大的(de)當地就(jiu)是缺(que)(que)(que)陷的(de)地址(zhi)當地。4.短路(lu)(lu)和(he)開路(lu)(lu)法(fa),短路(lu)(lu)法(fa)就(jiu)是將電(dian)路(lu)(lu)的(de)某(mou)(mou)一部(bu)分短路(lu)(lu)，然(ran)后(hou)(hou)通(tong)過示波器(qi)(qi)或(huo)萬用(yong)(yong)表檢驗的(de)作用(yong)(yong)來判(pan)(pan)(pan)別缺(que)(que)(que)陷點。開路(lu)(lu)法(fa)就(jiu)是將電(dian)路(lu)(lu)的(de)某(mou)(mou)一部(bu)分斷(duan)開，然(ran)后(hou)(hou)通(tong)過萬用(yong)(yong)表來測量(liang)電(dian)阻、電(dian)壓(ya)(ya)或(huo)電(dian)流來判(pan)(pan)(pan)別缺(que)(que)(que)陷點。
