故(gu)障排(pai)除：1)電(dian)吹(chui)風直接吹(chui)干；

2）用酒精浸泡(pao)刷洗，吹干，清除表面污物；

3）原則(ze)上巳被污濁的接線板應更換(huan)。

公司50 t 電子汽車衡(heng)有(you)時(shi)(shi)重(zhong)車開上后顯(xian)示負超載，重(zhong)新開機(ji)后有(you)時(shi)(shi)能恢(hui)復正常(chang)，此現象(xiang)經(jing)常(chang)發生。

故障分(fen)析：故障時(shi)有(you)時(shi)無(wu)，估計(ji)不是(shi)(shi)儀表的(de)(de)原因(yin)。檢(jian)查(cha)秤臺、連接件、限(xian)位(wei)都正常，排(pai)(pai)除機械方(fang)面原因(yin)。把(ba)接線板上(shang)所有(you)的(de)(de)焊(han)點重新(xin)檢(jian)查(cha)一遍，排(pai)(pai)除了(le)虛焊(han)或脫(tuo)焊(han)的(de)(de)可能。后用“替代法”和“扯(che)線法”查(cha)出故障是(shi)(shi)由某個傳感器引起的(de)(de)。經檢(jian)查(cha)確認有(you)一個傳感器的(de)(de)信(xin)號線被老(lao)鼠咬破，有(you)時(shi)能接觸上(shang)，則儀表正常，有(you)時(shi)則處于斷開(kai)狀態，儀表顯示負超載。

故障處(chu)理：把此傳(chuan)感器信號線從咬(yao)破皮處(chu)剪(jian)斷(duan)，用環氧樹脂處(chu)理后(hou)，做個接頭，汽車(che)衡恢復正常
