Lenz），廣州手持lcr電橋，C：電容(Capacitor)，R：電阻(Resistance)，LCR數(shù)字電橋就是能夠測(cè)量電感，電容，電阻，阻抗的儀器，這是一個(gè)傳統(tǒng)習(xí)慣的說(shuō)法，較早的阻抗測(cè)量用的是真正的電橋方法，隨著現(xiàn)代模擬和數(shù)字技術(shù)的發(fā)展，早已經(jīng)淘汰了這種測(cè)量方法，但LCR電橋的叫法一直沿用至今。如果是使用了微處理器的LCR電橋則叫LCR數(shù)字電橋。一般用戶又稱這些為：LCR測(cè)試儀、LCR電橋、LCR表、數(shù)字電橋、LCR Meter等等。圳市展榮新精密電子有限公司，專業(yè)從事電子變壓器、電感線圈、電容電阻等各類元器件測(cè)試儀之自主研發(fā)、制造和銷售，廣州手持lcr電橋?，F(xiàn)有的主要產(chǎn)品—電子變壓器綜合測(cè)試系統(tǒng)，廣州手持lcr電橋、精密LCR數(shù)字電橋和直流微電阻表等，并代理國(guó)內(nèi)外**品牌的測(cè)量?jī)x表。LCR數(shù)字電橋在測(cè)量?jī)x器方面做出了巨大的貢獻(xiàn).廣州手持lcr電橋</p><div

style="text-indent:25px">用LCR測(cè)試儀來(lái)測(cè)量零部件的參數(shù)時(shí)，其關(guān)鍵問(wèn)題在于測(cè)量誤差。首先是LCR測(cè)試儀本身的內(nèi)部誤差，還存在各種各樣的原因，而與試樣的連接所引起的誤差，就是其中之一。由于LCR測(cè)試儀的型號(hào)不同，可能的連接方法也會(huì)有區(qū)別，每種連接方法的各自特點(diǎn)。一般來(lái)說(shuō)，連接方法越麻煩，越能準(zhǔn)確地進(jìn)行測(cè)量。二端子法:雖然連接容易，但是由于接觸電阻、連接電纜的串聯(lián)阻抗（r）、連接電纜以及端子之間的雜散電容（Cs）會(huì)引起較大的誤差，如果不是中等數(shù)量級(jí)的阻抗，那么測(cè)量誤差就會(huì)比較大。三端子法:對(duì)測(cè)試電纜和試樣進(jìn)行屏蔽，通過(guò)抑制雜散電容，減少對(duì)于高阻抗零部件的測(cè)量誤差。主要可用于測(cè)量較小的電容量。湖南lcr電橋系統(tǒng)選擇LCR數(shù)字電橋采用先進(jìn)工藝和高密度電路設(shè)計(jì),濃縮大型LCR測(cè)試儀的精華,緊湊,小巧。</p><div

兩款產(chǎn)品加以說(shuō)明。TH2818：頻率20Hz—300KHz，基本準(zhǔn)確度0.05%。TH2828：頻率20Hz—1MHz，基本準(zhǔn)確度0.05%假定儀器測(cè)試條件均為慢速、電平1Vrms、溫度20oC，對(duì)100pF、10nF 電容器進(jìn)行測(cè)試，評(píng)估其在不同頻率下的測(cè)量準(zhǔn)確度，比如說(shuō)容量均為100pF，型號(hào)2818頻率100Hz的測(cè)試值為4.06，型號(hào)2828頻率100Hz的測(cè)試值為0.3。所以實(shí)驗(yàn)表明即便是相同基本準(zhǔn)確度的儀器，在不同量值被測(cè)件和不同頻率下其準(zhǔn)確度是有很大區(qū)別的。</p><p

style="text-indent:25px">LCR測(cè)試儀測(cè)試原理：Vx與Vr均是矢量電壓表，Rr是理想電阻。LCR測(cè)試儀自平衡電橋的意思是：當(dāng)DUT(Device Under Test)接入電路時(shí)，放大器的負(fù)反饋配置自動(dòng)使得OP輸入端虛地。Vx準(zhǔn)確測(cè)定DUT兩端電壓（DUT的Low電位是0），Vr與Rr測(cè)得DUT電流Ix，由此可計(jì)算Zx。LCR測(cè)試儀提高精度的方法是: 1,Hp,Lp,Hc,Lc盡量接近DUT; 2,減小測(cè)試電流Ix的回路面積&磁通量（關(guān)鍵是分析Ix，要配合使用Guard與Cable*小化回路面積);3,使用Gurard與Cable構(gòu)建地平面中斷信號(hào)線間的電場(chǎng)連接，雖然會(huì)增加信號(hào)線的對(duì)地電容（對(duì)地電容不影響測(cè)試結(jié)果），但是會(huì)減少信號(hào)線的互容。Guard與Cable的對(duì)地寄生阻抗（Zhg,Zlg) 不影響測(cè)試結(jié)果，電橋平衡時(shí)Zlg的兩端電壓是0，流向Rr的電流不會(huì)被Zlg分流，Zhg的分流作用不影響Hp的電壓測(cè)量。廣州手持lcr電橋</p><p
