電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)是(shi)(shi)根據通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)導體在(zai)磁(ci)(ci)場中受磁(ci)(ci)場力的(de)(de)(de)(de)(de)(de)作(zuo)用而制(zhi)成的(de)(de)(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)內部有(you)(you)一(yi)(yi)永磁(ci)(ci)體，在(zai)極間(jian)產生磁(ci)(ci)場，在(zai)磁(ci)(ci)場中有(you)(you)一(yi)(yi)個線圈，線圈兩(liang)(liang)端(duan)(duan)各(ge)有(you)(you)一(yi)(yi)個游(you)絲彈(dan)簧(huang)，彈(dan)簧(huang)各(ge)連接(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)的(de)(de)(de)(de)(de)(de)一(yi)(yi)個接(jie)(jie)線柱，在(zai)彈(dan)簧(huang)與線圈間(jian)由(you)一(yi)(yi)個轉(zhuan)軸連接(jie)(jie)，在(zai)轉(zhuan)軸相對于電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)的(de)(de)(de)(de)(de)(de)前端(duan)(duan)，有(you)(you)一(yi)(yi)個指針。指針偏轉(zhuan)。由(you)于磁(ci)(ci)場力的(de)(de)(de)(de)(de)(de)大小隨電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)增大而增大，所以(yi)(yi)就可以(yi)(yi)通過指針的(de)(de)(de)(de)(de)(de)偏轉(zhuan)程(cheng)度來觀察電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)的(de)(de)(de)(de)(de)(de)大小。這叫磁(ci)(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)，就是(shi)(shi)我們平時實驗室(shi)里用的(de)(de)(de)(de)(de)(de)那(nei)種。一(yi)(yi)般可直(zhi)接(jie)(jie)測(ce)(ce)量(liang)微安(an)(an)或毫安(an)(an)數量(liang)級的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)，為測(ce)(ce)更大的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)應(ying)有(you)(you)并聯電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)器(qi)（又稱(cheng)分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)）。主要采用磁(ci)(ci)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)表(biao)(biao)(biao)的(de)(de)(de)(de)(de)(de)測(ce)(ce)量(liang)機構。分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值要使(shi)滿(man)量(liang)程(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)通過時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)滿(man)偏轉(zhuan)，即電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)指示(shi)達到大。對于幾(ji)安(an)(an)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)，可在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)內設(she)置分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)。對于幾(ji)安(an)(an)以(yi)(yi)上的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)，則(ze)采用外(wai)附分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)。大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值很小，為避免引(yin)(yin)線電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)和接(jie)(jie)觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)附加于分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)而引(yin)(yin)起誤差，分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)要制(zhi)成四(si)端(duan)(duan)形式，即有(you)(you)兩(liang)(liang)個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)端(duan)(duan)，兩(liang)(liang)個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)端(duan)(duan)。例如，當用外(wai)附分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)和毫伏(fu)表(biao)(biao)(biao)來測(ce)(ce)量(liang)200A的(de)(de)(de)(de)(de)(de)大電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)時，若(ruo)采用的(de)(de)(de)(de)(de)(de)毫伏(fu)表(biao)(biao)(biao)標(biao)準(zhun)化(hua)量(liang)程(cheng)為45mV（或75mV），那(nei)么分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)值為0.045/200=0.000225Ω（或0.075/200=0.000375Ω）。若(ruo)利用環(huan)形（或稱(cheng)梯級）分(fen)(fen)(fen)(fen)流(liu)(liu)(liu)(liu)(liu)(liu)器(qi)，可制(zhi)成多量(liang)程(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)(liu)(liu)表(biao)(biao)(biao)。

電(dian)流表(biao)和電(dian)壓表(biao)的測量(liang)機構基本相同(tong)，但在測量(liang)線路中的連(lian)接有所不同(tong)。因此，在選擇和使(shi)用電(dian)流表(biao)和電(dian)壓表(biao)時應注(zhu)意(yi)以(yi)下幾點。

⒈ 類(lei)型的(de)(de)(de)(de)選(xuan)擇。當被(bei)測(ce)(ce)量是(shi)(shi)直流(liu)時，應選(xuan)直流(liu)表(biao)，即磁電(dian)(dian)(dian)系測(ce)(ce)量機構(gou)的(de)(de)(de)(de)儀(yi)(yi)(yi)表(biao)。當被(bei)測(ce)(ce)量是(shi)(shi)交流(liu)時，應注意其(qi)(qi)波(bo)形與頻率。若(ruo)為(wei)正弦(xian)波(bo)，只需(xu)測(ce)(ce)出有效值(zhi)(zhi)(zhi)即可換算為(wei)其(qi)(qi)他值(zhi)(zhi)(zhi)（如(ru)大值(zhi)(zhi)(zhi)、平均值(zhi)(zhi)(zhi)等），采(cai)用(yong)任意一種(zhong)交流(liu)表(biao)即可；若(ruo)為(wei)非正弦(xian)波(bo)，則(ze)應區分需(xu)測(ce)(ce)量的(de)(de)(de)(de)是(shi)(shi)什么值(zhi)(zhi)(zhi)，有效值(zhi)(zhi)(zhi)可選(xuan)用(yong)磁系或鐵(tie)磁電(dian)(dian)(dian)動(dong)系測(ce)(ce)量機構(gou)的(de)(de)(de)(de)儀(yi)(yi)(yi)表(biao)，平均值(zhi)(zhi)(zhi)則(ze)選(xuan)用(yong)整流(liu)系測(ce)(ce)量機構(gou)的(de)(de)(de)(de)儀(yi)(yi)(yi)表(biao)。電(dian)(dian)(dian)動(dong)系測(ce)(ce)量機構(gou)的(de)(de)(de)(de)儀(yi)(yi)(yi)表(biao)常用(yong)于交流(liu)電(dian)(dian)(dian)流(liu)和電(dian)(dian)(dian)壓的(de)(de)(de)(de)精密測(ce)(ce)量。

⒉ 準(zhun)確(que)(que)度(du)的(de)選(xuan)擇。因儀(yi)表的(de)準(zhun)確(que)(que)度(du)越高(gao)，價格越貴，維修也(ye)較(jiao)困(kun)難。而且，若其他條件配合(he)不當，再(zai)高(gao)準(zhun)確(que)(que)度(du)等級的(de)儀(yi)表，也(ye)未必能(neng)得到準(zhun)確(que)(que)的(de)測量(liang)結果。因此，在選(xuan)用準(zhun)確(que)(que)準(zhun)確(que)(que)度(du)較(jiao)低的(de)儀(yi)表可滿足測量(liang)要求的(de)情況下，就不要選(xuan)用高(gao)準(zhun)確(que)(que)度(du)的(de)儀(yi)表。通常0.1級和0.2級儀(yi)表作(zuo)為(wei)標準(zhun)表選(xuan)用；0.5級和1.0級儀(yi)表作(zuo)為(wei)實(shi)驗室測量(liang)使(shi)用；1.5級以下的(de)儀(yi)表一般作(zuo)為(wei)工程(cheng)測量(liang)選(xuan)用。

⒊ 量(liang)(liang)程的(de)選擇。要(yao)充分(fen)發揮儀(yi)表(biao)(biao)準確度的(de)作用，還必須(xu)根據被測(ce)量(liang)(liang)的(de)大小(xiao)，合理選用儀(yi)表(biao)(biao)量(liang)(liang)限，如選擇不當，其(qi)(qi)測(ce)量(liang)(liang)誤(wu)差將會很大。一(yi)般使儀(yi)表(biao)(biao)對被測(ce)量(liang)(liang)的(de)指示大于儀(yi)表(biao)(biao)大量(liang)(liang)程的(de)1/2~2/3以上，而不能超過其(qi)(qi)大量(liang)(liang)程。

⒋ 內(nei)阻的選擇(ze)。選擇(ze)儀表(biao)時(shi)，還應根據(ju)被(bei)測阻抗的大小(xiao)來選擇(ze)儀表(biao)的內(nei)阻，否(fou)則會帶來較大的測量誤差(cha)。因(yin)內(nei)阻的大小(xiao)反映儀表(biao)本身功率的消耗，所(suo)以(yi)，測量電(dian)流(liu)時(shi)，應選用內(nei)阻盡(jin)可能小(xiao)的電(dian)流(liu)表(biao)；測量電(dian)壓(ya)時(shi)，應選用內(nei)阻盡(jin)可能大的電(dian)壓(ya)表(biao)。

指針式電流表都是由靈敏(min)電流(liu)(liu)計改裝而來的。靈敏(min)電流(liu)(liu)計即使靈敏度再(zai)高，通(tong)過(guo)(guo)(guo)(guo)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)多(duo)不(bu)超過(guo)(guo)(guo)(guo)30微安，而學生(sheng)用電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表(biao)測得的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)強(qiang)度都是(shi)0.6A，或者3A，遠(yuan)遠(yuan)超出大值(zhi)。電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表(biao)既要讓電(dian)(dian)(dian)(dian)路上的(de)(de)全部電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)通(tong)過(guo)(guo)(guo)(guo)，又不(bu)允許(xu)通(tong)過(guo)(guo)(guo)(guo)線圈的(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)超過(guo)(guo)(guo)(guo)安全限度。電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)表(biao)是(shi)與(yu)被測用電(dian)(dian)(dian)(dian)器串聯(lian)的(de)(de)，所(suo)以改裝時要分(fen)流(liu)(liu)(liu)(liu)。將靈敏電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)計與(yu)一個阻值(zhi)較小(xiao)的(de)(de)電(dian)(dian)(dian)(dian)阻并聯(lian)，這樣(yang)就會(hui)使大部分(fen)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)通(tong)過(guo)(guo)(guo)(guo)電(dian)(dian)(dian)(dian)阻，小(xiao)部分(fen)經(jing)過(guo)(guo)(guo)(guo)表頭。這時將表頭標上新的(de)刻度(du)，就可(ke)以了。
