儀器儀表維修作業

1、用(yong)(yong)萬(wan)(wan)用(yong)(yong)表(biao)(biao)歐姆擋時(shi)，牢記(ji)(ji)不(bu)要(yao)(yao)(yao)帶電(dian)(dian)丈(zhang)(zhang)量(liang)(liang)。2、運用(yong)(yong)邏輯筆、示(shi)波(bo)器(qi)(qi)(qi)檢查信號時(shi)，要(yao)(yao)(yao)注意不(bu)使探(tan)針一(yi)起觸摸兩個丈(zhang)(zhang)量(liang)(liang)引腳，由于這種狀況(kuang)的(de)(de)本質是(shi)在(zai)加電(dian)(dian)的(de)(de)狀況(kuang)下(xia)(xia)形成短(duan)路(lu)。3、檢查電(dian)(dian)源中的(de)(de)濾波(bo)電(dian)(dian)容(rong)時(shi)，應(ying)(ying)先將(jiang)電(dian)(dian)解電(dian)(dian)容(rong)器(qi)(qi)(qi)的(de)(de)正負極短(duan)路(lu)一(yi)下(xia)(xia)，并(bing)且(qie)短(duan)路(lu)時(shi)不(bu)要(yao)(yao)(yao)用(yong)(yong)表(biao)(biao)筆線(xian)(xian)來替(ti)代導線(xian)(xian)對電(dian)(dian)容(rong)器(qi)(qi)(qi)進行放電(dian)(dian)，由于這樣簡單燒斷芯(xin)線(xian)(xian)。能(neng)夠取(qu)一(yi)只帶燈(deng)頭(tou)引線(xian)(xian)的(de)(de)220V，60～100W的(de)(de)燈(deng)，接(jie)(jie)(jie)于電(dian)(dian)容(rong)器(qi)(qi)(qi)的(de)(de)兩端，在(zai)放電(dian)(dian)剎(cha)那間(jian)燈(deng)泡會(hui)亮光(guang)。4、在(zai)濕潤(run)環境下(xia)(xia)維修(xiu)外表(biao)(biao)毛(mao)病(bing)時(shi)，對印刷線(xian)(xian)路(lu)用(yong)(yong)萬(wan)(wan)用(yong)(yong)表(biao)(biao)測其(qi)各點(dian)是(shi)不(bu)是(shi)曉暢很有必要(yao)(yao)(yao)，由于這種狀況(kuang)下(xia)(xia)的(de)(de)首要(yao)(yao)(yao)毛(mao)病(bing)是(shi)銅箔腐蝕。5、維修(xiu)外表(biao)(biao)內(nei)部電(dian)(dian)路(lu)時(shi)，假(jia)如裝(zhuang)置(zhi)元件的(de)(de)接(jie)(jie)(jie)點(dian)和電(dian)(dian)路(lu)板(ban)(ban)上(shang)涂了絕緣清漆(qi)(qi)，丈(zhang)(zhang)量(liang)(liang)各點(dian)參數時(shi)可(ke)用(yong)(yong)普通手縫針焊在(zai)萬(wan)(wan)用(yong)(yong)表(biao)(biao)的(de)(de)表(biao)(biao)筆上(shang)，以便刺穿漆(qi)(qi)層(ceng)直接(jie)(jie)(jie)丈(zhang)(zhang)量(liang)(liang)各點(dian)，而(er)不(bu)用(yong)(yong)大面積剝離漆(qi)(qi)層(ceng)。6、不(bu)要(yao)(yao)(yao)帶電(dian)(dian)插(cha)拔(ba)(ba)各種控(kong)制板(ban)(ban)和插(cha)頭(tou)。由于在(zai)加電(dian)(dian)狀況(kuang)下(xia)(xia)，插(cha)拔(ba)(ba)控(kong)制板(ban)(ban)會(hui)發(fa)生較強(qiang)的(de)(de)感應(ying)(ying)電(dian)(dian)動勢，這時(shi)剎(cha)那間(jian)反擊電(dian)(dian)壓很高，很簡單損壞相(xiang)應(ying)(ying)的(de)(de)控(kong)制板(ban)(ban)和插(cha)頭(tou)。7、維修(xiu)時(shi)不(bu)要(yao)(yao)(yao)盲目亂敲亂碰，避免(mian)擴展毛(mao)病(bing)，越修(xiu)越壞。8、拆(chai)開、調整外表(biao)(biao)時(shi)，應(ying)(ying)記(ji)(ji)載本來的(de)(de)位置(zhi)，以便復(fu)原。9、修(xiu)補(bu)精密儀(yi)器(qi)(qi)(qi)外表(biao)(biao)時(shi)，如不(bu)慎將(jiang)小零件彈飛，應(ying)(ying)首先判別也許飛落的(de)(de)當地，切勿東找一(yi)下(xia)(xia)，西翻一(yi)下(xia)(xia)，可(ke)采(cai)納(na)磁鐵掃描和視野掃描辦(ban)法進行尋覓。
