什么叫做微歐計？微歐計工作原理是什么？ </p> <p> 微歐計也叫數(shù)字微歐計，毫歐表，是一種測量低值電阻的數(shù)字式儀表。它的基本原理是：利用直流恒流源在被測電阻Rx上產(chǎn)生直流電壓降Ux，然后通過電壓放大和A/D轉(zhuǎn)換器變?yōu)閿?shù)字顯示的電阻值。在測量過程中，采用“四端子”（電流端子、電位端子）測量法，消除引線和接觸電阻帶來的誤差。數(shù)字微歐計具有操作簡便、省時、數(shù)顯、對操作人員要求不高等優(yōu)點。 </p> <p> <p> 微歐計的工作原理是通過電橋原理（國外也稱為開爾文原理）四線法測量的，即在電阻兩端施加1個恒流，再通過儀器檢測其兩端的電壓，然后通過儀器自動計算后得出電阻值。其優(yōu)點是測量的數(shù)據(jù)接近電阻在工作狀態(tài)下的真實阻值，且消除了測試線本身電阻的影響。 </p> <p> 而普通萬用表測量電阻一般采用比例法，被測電阻與標準電阻串聯(lián)，測量標準電阻和被測電阻的電壓，兩者電流相同，根據(jù)標準電阻的阻值換算出被測電阻的阻值。實際測量電路也有把標準電阻對應電壓作為基準電壓，這樣，直接測量被測電阻兩端的電壓即可。 </p> 便攜式毫歐表，四線法原理測量，精度更高。海南毫歐表的品牌</p><p style="text-indent:25px">數(shù)字式毫歐表的使用方法，視頻教程哪里有？找深圳茂迪黃富強。廣東老毫歐表</p><p> 毫歐表的調(diào)零方法： </p> <p> <p> ①機械調(diào)零 </p> <p> 當兩表筆分開時baidu,即待測電阻為無窮大時,由歐姆zhi定律知此時電流強度為零。即當兩表筆分開時dao，電表指針指示的狀態(tài)應為零電流和無窮大歐姆。但是由于各種原因，當兩表筆分開時電表的指針有時并沒有指在零電流刻度上，這就需要進行機械調(diào)零。用螺旋刀轉(zhuǎn)動機械調(diào)零螺絲帶動指針轉(zhuǎn)動，使指針指無窮大歐姆刻度處。 </p> <p> ②歐姆調(diào)零 </p> <p> 當兩表筆短接時，由歐姆定律知，可以通過調(diào)節(jié)滑動變阻器使電流表滿偏，即令指針指電流表的滿偏電流刻度處，亦即零歐姆刻度處。即當兩表筆短接時, </p> <p> 電表指針指示的狀態(tài)應為滿偏電流和零歐姆阻值。否則，調(diào)節(jié)變阻器使電流表指針指滿偏電流刻度處，亦即零歐姆刻度處，即完成歐姆調(diào)零。 </p>
