（3）測量(讀數(shù))：把兩支表筆分別與待測電阻的兩端相接，進(jìn)行測量，指針示數(shù)乘以倍率數(shù)，即為待測電阻的阻值。 </p> <p> （4）實(shí)驗(yàn)完畢，應(yīng)將兩表筆從插孔中拔出，并將選擇開關(guān)置于“OFF”擋或交流電壓比較高擋。如果歐姆表長期不用，應(yīng)取出表內(nèi)的電池。 </p> <p>

毫歐電阻表介紹，毫歐電阻：即阻值較小，一般小于1Ω的低阻值電阻。毫歐電阻又稱采樣電阻、電流檢測電阻、電流感測電阻、取樣電阻、微電阻。毫歐電阻主要有康銅電阻、錳銅電阻、低阻值貼片電阻。毫歐電阻一般具有導(dǎo)電能力強(qiáng)，過電流大的特點(diǎn)。目前國內(nèi)毫歐電阻生產(chǎn)商較多，研發(fā)能力參差不齊。 </p> <p> 毫歐電阻作用編輯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，放在電路中對電路本身的影響很小，可以用于對線路中電流的采樣。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)化為電壓來測量或反饋。或者在線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。毫歐表METRAHIT 27I”是一種精密測量低電阻的數(shù)字式測量儀器。廣西t477w毫歐表使用方法</p><p style="text-indent:25px">毫歐表與微歐計(jì)的區(qū)別，是否有二合一的設(shè)備呢？廣西27ex 毫歐表</p><p> 毫歐表的原理四線測量的毫歐表，接線端為u+ u- I+ I-； </p> <p> 一般使用的時(shí)候，U+是和I+接到一起，U-和I-接到一起，這樣就是為了將測量的誤差減小的比較低。其實(shí)儀器是一個(gè)恒流源，這樣你應(yīng)該明白了吧，儀器的輸出電流是不變的，當(dāng)你測量的電阻阻值不一樣時(shí)，在電阻上產(chǎn)生的壓降就不一樣。通過U+U-到內(nèi)部放大，轉(zhuǎn)換，再驅(qū)動(dòng)指針表頭或者經(jīng)過A/D轉(zhuǎn)換用數(shù)碼管顯示出來。我用過接地電阻測試儀，原理是一樣的就是名稱不一樣，接地電阻也是十幾個(gè)毫歐。
