style="text-indent:25px">作為一個(gè)新用戶，怎樣選擇一款lcr數(shù)字電橋？首先是看儀器的測(cè)試準(zhǔn)確度，看儀器的測(cè)試頻率，看儀器的測(cè)試電平。儀器的輸出阻抗或稱內(nèi)阻。其他視客戶使用具體情況而定，或者可以根據(jù)客戶的實(shí)際情況向同深圳市展榮新精密電子有限公司技術(shù)咨詢。對(duì)于一個(gè)已知的“電容”，客戶該選用什么樣的測(cè)試條件?1.小于100pF電容用1MHZ頻率測(cè)量，lcr電橋國(guó)產(chǎn)，中等容量如(1000pF-10uF)用1KHZ,10KHZ,100KHZ，lcr電橋國(guó)產(chǎn)，國(guó)家標(biāo)準(zhǔn)測(cè)試中等電容的測(cè)試頻率標(biāo)準(zhǔn)是1KHZ。電解類如鋁電解，lcr電橋國(guó)產(chǎn)，鉭電解等用100HZ或120HZ。2.從電平的角度說(shuō)大部分電容對(duì)電平不敏感，不同電平測(cè)試變化不大，但有些介電常數(shù)大的電容與電平非常敏感，應(yīng)仔細(xì)選擇電平。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="lcr電橋國(guó)產(chǎn)"

style="text-indent:25px">在我們的生活中電氣行業(yè)到處可見(jiàn)，隨著經(jīng)濟(jì)的發(fā)展，電氣行業(yè)的發(fā)展越來(lái)越快，電子產(chǎn)品部件也成為比較重要的部件之一。其中數(shù)字橋已成為工業(yè)生產(chǎn)活動(dòng)不可或缺的設(shè)備。但是，很多人不知道數(shù)字橋的原理是什么，那么就來(lái)簡(jiǎn)單介紹一下數(shù)字橋的原理吧。數(shù)字橋的測(cè)量對(duì)象是阻抗元件的參數(shù)，包括交流電阻r、電感l(wèi)及其質(zhì)量系數(shù)q、電容c及其損耗系數(shù)d。其測(cè)量用頻率從商用頻率到約100千赫?；緶y(cè)量誤差為0.02%，一般為0.1%左右。數(shù)字橋的原理可以表示為Zx=Ux/Ix=Rr * Ux/Ur。這個(gè)公式是相位量關(guān)系公式。從這個(gè)結(jié)構(gòu)來(lái)看，數(shù)字橋只是繼承了橋的傳統(tǒng)稱呼。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="lcr電橋國(guó)產(chǎn)" src="https://tyunfile.71360.com/UploadFile/ZRX888/637284365175302734/4158537.png"></div><p style="text-indent:25px">LCR電橋列表掃描：鑒于元件對(duì)頻率、電平、直流偏置電壓、直流偏置電流的相關(guān)性。即對(duì)多點(diǎn)頻率（或電平、偏壓、偏流）掃描測(cè)量，并將測(cè)量值同時(shí)顯示，還可對(duì)測(cè)試值進(jìn)行比較判別。偏流的列表掃描需與同惠的電感偏流源配合使用。測(cè)試端配置：傳統(tǒng)的LCR 數(shù)字電橋提供了五端測(cè)試端配置。這種配置有效解決了引線電阻對(duì)測(cè)試結(jié)果的影響及測(cè)試端子對(duì)地的分布電容。然而，五端配置阻抗測(cè)試下限為10mΩ，且不能解決測(cè)試線間相互電磁藕合的影響，表現(xiàn)為低阻抗測(cè)試時(shí)使用開(kāi)而文測(cè)試電纜時(shí)引線位置的移動(dòng)便會(huì)造成測(cè)試結(jié)果的變化。TH2828/A/S 的四端對(duì)配置方法不僅阻抗測(cè)試下限達(dá)到1mΩ，且有效解決測(cè)試線間電磁耦合的影響。</p></p><br /><p>文章來(lái)源地址: http://www.cdcfah.com/cp/426091.html</p></div></div></div></div></div><div id="u9dzdzl" class="page-right
