將靈敏電流計改裝成

電流表

指針(zhen)式電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)都是(shi)(shi)(shi)由(you)靈(ling)敏(min)(min)(min)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)計(ji)改裝(zhuang)而來的(de)(de)(de)(de)。靈(ling)敏(min)(min)(min)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)計(ji)即(ji)使靈(ling)敏(min)(min)(min)度(du)再高，通(tong)過(guo)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)不(bu)超過(guo)30微安(an)，而學生用電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)測得的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)強度(du)都是(shi)(shi)(shi)0.6A，或者(zhe)3A，遠(yuan)遠(yuan)超出醉(zui)大值。電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)既要(yao)讓電(dian)(dian)(dian)(dian)(dian)路上(shang)的(de)(de)(de)(de)全(quan)部(bu)(bu)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)通(tong)過(guo)，又(you)不(bu)允許通(tong)過(guo)線圈(quan)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)超過(guo)安(an)全(quan)限度(du)。電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)表(biao)是(shi)(shi)(shi)與被測用電(dian)(dian)(dian)(dian)(dian)器串聯的(de)(de)(de)(de)，所以(yi)改裝(zhuang)時(shi)要(yao)分流(liu)(liu)(liu)。將(jiang)靈(ling)敏(min)(min)(min)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)計(ji)與一個阻值較小(xiao)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)阻并聯，這(zhe)樣就會(hui)使大部(bu)(bu)分電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)通(tong)過(guo)電(dian)(dian)(dian)(dian)(dian)阻，小(xiao)部(bu)(bu)分經過(guo)表(biao)頭(tou)。這(zhe)時(shi)將(jiang)表(biao)頭(tou)標(biao)上(shang)新的(de)(de)(de)(de)刻(ke)度(du)，就可以(yi)了。

直(zhi)流(liu)電流(liu)表的常規檢查

  電流(liu)表讀(du)數(shu)(shu)穩定(ding)性能(neng)檢查(cha)：在進行電流(liu)表測試功能(neng)檢查(cha)時，正泰電流(liu)表報價，被測電流(liu)表在穩定(ding)輸入后，電流(liu)表的(de)(de)讀(du)數(shu)(shu)在1min內的(de)(de)1大值(zhi)與1小(xiao)值(zhi)的(de)(de)差(cha)值(zhi)應不超過該量程(cheng)誤差(cha)的(de)(de)20%。

    電流表(biao)的(de)(de)機(ji)械調(diao)零：儀表(biao)在水(shui)平放置(zhi)時各(ge)個(ge)檔(dang)位的(de)(de)指(zhi)示針應(ying)在顯示盤的(de)(de)零刻度線(xian)上，不符合要求的(de)(de)應(ying)在儀表(biao)的(de)(de)機(ji)械調(diao)零處將其調(diao)整到零刻度線(xian)上。
