毫bai歐表”是一種精密測(cè)量低電阻的數(shù)字式測(cè)量儀du器。主要zhi用于測(cè)量電纜的導(dǎo)線電阻，開關(guān)、接插件、dao繼電器的接觸電阻，線圈、電動(dòng)機(jī)、變壓器繞組的電阻以及金屬鉚接電阻。微電阻計(jì)和萬用表的區(qū)別是輸出電流和量程范圍不同。我以“GY339毫歐表”為例，舉例說明，“毫歐表”如何選型，要注意一下幾點(diǎn)： </p> <p> 1.測(cè)量范圍: 0.001-2000Ω,分辨率：1uΩ. </p> <p> 2.采用“四端子”測(cè)試技術(shù)，消除接觸電阻和引線電阻引起的誤差. </p> <p> 3.交直流兩用，內(nèi)置鉛酸蓄電池供電，便攜式機(jī)箱。 </p> <p> <br /> </p><p> 恒流源電流流經(jīng)的系統(tǒng)內(nèi)部線路電阻和連接飛機(jī)的測(cè)試導(dǎo)線的導(dǎo)線電阻可達(dá)三十幾毫歐，可作為系統(tǒng)常數(shù)誤差予以消除。難以消除的誤差是隨機(jī)誤差，來自于測(cè)試線路與機(jī)上連接點(diǎn)的隨機(jī)接觸電阻。每次測(cè)量時(shí)，擰緊測(cè)試線的力度不同、接觸表面的清潔度不同，其接觸電阻完全是隨機(jī)的，變化范圍可達(dá)幾個(gè)毫歐。為此采用如圖4所示的測(cè)試連接電路予以消除。圖4消除隨機(jī)誤差的測(cè)試連接圖測(cè)試原理是四線測(cè)試法。選擇L1~L4四根導(dǎo)線為相同導(dǎo)線電阻的鍍銀導(dǎo)線。M1、M2為機(jī)上測(cè)試連接點(diǎn)。在同一個(gè)測(cè)試點(diǎn)上擰緊兩根測(cè)試線，L1和L2，L3和L4。導(dǎo)線的另一端接至測(cè)試接線盒的接觸電阻小于φ6鍍金接線柱。采用手動(dòng)連接活動(dòng)鍍金接線片的辦法，構(gòu)成三種測(cè)試狀態(tài)：R+接T1、R―接N1，測(cè)量出L1、L2及接觸點(diǎn)M1的接觸電阻；R+接N2、R―接T2，測(cè)量出L3、L4及接觸點(diǎn)M2的接觸電阻。將這兩個(gè)電阻值取平均值作為測(cè)試線路的系統(tǒng)誤差。***測(cè)出R+接N2、R―接N1的電阻值，減去上述測(cè)得的測(cè)試線路系統(tǒng)誤差，即得到機(jī)體電阻值。5測(cè)試軟件流程圖如圖5所示，單片機(jī)采用查詢方式響應(yīng)測(cè)試鍵控。用4個(gè)鍵對(duì)應(yīng)四個(gè)測(cè)試狀態(tài)，且及時(shí)顯示測(cè)試結(jié)果以便于操作者判斷。程序判斷四個(gè)電阻測(cè)試完后，自動(dòng)修正各種誤差。毫歐表METRAHIT

歐姆的du物理符號(hào)為“Ω </p> <p> ”。簡稱“歐zhi”，Ωμ?γα（大寫Ωdao，小寫ω），又稱為大O，是第二十四個(gè)希臘字母，亦是***一個(gè)希臘字母。 </p> <p> 歐姆——以國際歐姆作為電阻單位，它以等于109CGSM電阻的歐姆作為基礎(chǔ)，用恒定電流在融冰溫度時(shí)通過質(zhì)量為14.4521克、長度為106.3厘米、橫截面恒定的**柱受到的電阻。 </p> <p> 【毫歐】： </p> <p> 毫這個(gè)是中文表達(dá)方法,毫歐的物理符號(hào)是mΩ,數(shù)量級(jí)為10的負(fù)三次方。一般小于1Ω的低阻值電阻就要用mΩ來表示。 </p> <p> 毫歐電阻由其性能特點(diǎn)，往往在電路中用作采樣。由于阻值小，放在電路中對(duì)電路本身的影響很小，可以用于對(duì)線路中電流的采樣。一般來說，電阻放在電路里，可以用作反饋，將電流信號(hào)，轉(zhuǎn)化為電壓來測(cè)量或反饋?；蛘咴诰€路中需要做過流保護(hù)時(shí)，電路設(shè)計(jì)簡單，實(shí)際操作成本低，安全可靠。 </p> <p> <br
