使用步驟

⒈校零，正泰電流表供應商，用平(ping)口改錐調(diao)整校零按鈕。

⒉選用(yong)量程（用(yong)經(jing)驗估(gu)計或采用(yong)試觸法）

電流表

歸結起來有三看和三問先(xian)看清電流(liu)表(biao)的(de)(de)(de)量程(cheng)，一(yi)般在表(biao)盤上有標記(ji)。確認格的(de)(de)(de)一(yi)個表(biao)示多(duo)少(shao)安培把(ba)電流(liu)表(biao)的(de)(de)(de)正(zheng)負接線(xian)柱接入電路后(hou)，觀察指(zhi)針(zhen)位置，就可(ke)(ke)以(yi)讀數了。此外還要選擇合適(shi)量程(cheng)的(de)(de)(de)電流(liu)表(biao)。可(ke)(ke)以(yi)先(xian)試觸一(yi)下，若指(zhi)針(zhen)擺(bai)動(dong)不(bu)明顯，無錫正(zheng)泰電流(liu)表(biao)，則換(huan)小量程(cheng)的(de)(de)(de)表(biao)。若指(zhi)針(zhen)擺(bai)動(dong)大(da)角度，則換(huan)大(da)量程(cheng)的(de)(de)(de)表(biao)。一(yi)般指(zhi)針(zhen)在表(biao)盤中間左右，讀數比較合適(shi)。

一看(kan)：量(liang)程。電流(liu)表的(de)測量(liang)范(fan)圍。

二看：分度值。表盤的(de)一小格(ge)代表多少。

三看(kan)：指(zhi)針位置。指(zhi)針的位置包含了(le)多少個分度值。

直流(liu)電流(liu)表的常規檢查

  電(dian)流表(biao)讀(du)數(shu)穩定(ding)性能檢(jian)查：在進行(xing)電(dian)流表(biao)測(ce)試(shi)功(gong)能檢(jian)查時，正泰電(dian)流表(biao)報價，被(bei)測(ce)電(dian)流表(biao)在穩定(ding)輸入后，電(dian)流表(biao)的讀(du)數(shu)在1min內的1大值與1小值的差值應不超過(guo)該量(liang)程誤差的20%。

    電流表的(de)機械(xie)調(diao)(diao)零(ling)(ling)：儀表在(zai)水平(ping)放置時(shi)各個檔位的(de)指(zhi)示針應(ying)在(zai)顯示盤的(de)零(ling)(ling)刻度(du)線(xian)上，不符(fu)合要求的(de)應(ying)在(zai)儀表的(de)機械(xie)調(diao)(diao)零(ling)(ling)處將其調(diao)(diao)整到零(ling)(ling)刻度(du)線(xian)上。

電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)是根據通電(dian)(dian)(dian)(dian)導體(ti)在磁場中受磁場力(li)的(de)作用而制成的(de)。電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)內部有一(yi)永(yong)磁體(ti)，在極間產生磁場，在磁場中有一(yi)個線圈，線圈兩端各有一(yi)個游絲(si)彈(dan)簧(huang)，正泰電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)哪(na)家好，彈(dan)簧(huang)各連接電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)的(de)一(yi)個接線柱，在彈(dan)簧(huang)與線圈間由(you)一(yi)個轉(zhuan)軸(zhou)連接，在轉(zhuan)軸(zhou)相對于(yu)電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)的(de)前端，有一(yi)個指針(zhen)。指針(zhen)偏轉(zhuan)。由(you)于(yu)磁場力(li)的(de)大(da)小隨電(dian)(dian)(dian)(dian)流(liu)(liu)增(zeng)(zeng)大(da)而增(zeng)(zeng)大(da)，所以(yi)就可以(yi)通過指針(zhen)的(de)偏轉(zhuan)程度來觀察電(dian)(dian)(dian)(dian)流(liu)(liu)的(de)大(da)小。一(yi)般(ban)可直接測(ce)量(liang)微安或毫(hao)安數量(liang)級的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)，為測(ce)更(geng)大(da)的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)，電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)應有并聯(lian)電(dian)(dian)(dian)(dian)阻器(qi)（又稱分流(liu)(liu)器(qi)）。主要采用磁電(dian)(dian)(dian)(dian)系電(dian)(dian)(dian)(dian)表(biao)(biao)的(de)測(ce)量(liang)機構。分流(liu)(liu)器(qi)的(de)電(dian)(dian)(dian)(dian)阻值要使滿量(liang)程電(dian)(dian)(dian)(dian)流(liu)(liu)通過時(shi)，電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)滿偏轉(zhuan)，即電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)指示達到醉大(da)。
