直流電流表的常規檢查

電(dian)流(liu)(liu)(liu)表(biao)讀(du)數穩定性能(neng)檢查：在(zai)進(jin)行電(dian)流(liu)(liu)(liu)表(biao)測試功能(neng)檢查時，被測電(dian)流(liu)(liu)(liu)表(biao)在(zai)穩定輸(shu)入后(hou)，電(dian)流(liu)(liu)(liu)表(biao)的(de)讀(du)數在(zai)1min內(nei)的(de)1大值與(yu)1小值的(de)差(cha)值應不超過(guo)該量程誤差(cha)的(de)20%。

電流表(biao)(biao)的(de)(de)(de)機(ji)械調零(ling)：儀(yi)(yi)表(biao)(biao)在水平放置(zhi)時各個檔位的(de)(de)(de)指(zhi)示(shi)針應在顯示(shi)盤的(de)(de)(de)零(ling)刻(ke)度線上，不(bu)符(fu)合要求的(de)(de)(de)應在儀(yi)(yi)表(biao)(biao)的(de)(de)(de)機(ji)械調零(ling)處將其調整到零(ling)刻(ke)度線上。

電流表內外接法產生(sheng)誤差(cha)的原因

當選用外接法時(shi)，江(jiang)蘇(su)正泰電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表，電(dian)(dian)(dian)(dian)(dian)(dian)壓表與電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)并(bing)聯，電(dian)(dian)(dian)(dian)(dian)(dian)壓表的(de)(de)(de)讀數就是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)兩端的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓，正泰電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表供應商，但電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表測(ce)量的(de)(de)(de)是(shi)通(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)和電(dian)(dian)(dian)(dian)(dian)(dian)壓表的(de)(de)(de)總電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，因此(ci)測(ce)量值(zhi)要小于(yu)真(zhen)實值(zhi)，實際上測(ce)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值(zhi)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)壓表內(nei)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)和電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)并(bing)聯的(de)(de)(de)阻(zu)(zu)值(zhi)。如果(guo)電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)Rx的(de)(de)(de)值(zhi)遠小于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)壓表的(de)(de)(de)內(nei)阻(zu)(zu)RV，電(dian)(dian)(dian)(dian)(dian)(dian)壓表分去的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)很小，這時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表測(ce)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)就接近于(yu)通(tong)過電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，所以外接法適合于(yu)測(ce)小電(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)。
