兩款產(chǎn)品加以說明。TH2818：頻率20Hz—300KHz，基本準(zhǔn)確度0，惠州數(shù)字電橋lcr系統(tǒng).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，比如說容量均為100pF，型號(hào)2818頻率100Hz的測(cè)試值為4.06，惠州數(shù)字電橋lcr系統(tǒng)，型號(hào)2828頻率100Hz的測(cè)試值為0.3，惠州數(shù)字電橋lcr系統(tǒng)。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。LCR數(shù)字電橋主要由正弦信號(hào)發(fā)生器、精密量程電阻、鑒相器和高精度A/D轉(zhuǎn)換器組成。惠州數(shù)字電橋lcr系統(tǒng)</p><div

style="text-indent:25px">對(duì)于LCR數(shù)字電橋的使用來說，正確的選擇所需要的電阻頻率很重要。我們需要知道幾個(gè)選擇的規(guī)則。電容小于2nF，選擇，選擇串聯(lián)1KHz，選用高的測(cè)試信號(hào)可提高測(cè)試精度，同樣能量測(cè)大于1000μF以上電容。電感小于2mH，用串聯(lián)1KHz，選擇高測(cè)試頻率可提高測(cè)試精度。電感大于200H，并聯(lián)，120Hz，選擇低測(cè)試頻率可提高測(cè)試精度。電阻大于等于 1K Ω，選擇并聯(lián)120Hz(100Hz)，選擇低頻減少交流影響，選擇“并聯(lián)”，是因?yàn)榱繙y(cè)過程中出現(xiàn)電抗部份，等效為被測(cè)件并聯(lián)一個(gè)電容呈現(xiàn)的高電抗，用并聯(lián)模式減小這種影響，如果Q＜0.1，已存在小電容影響。江西手持lcr電橋系統(tǒng)LCR測(cè)試夾具或測(cè)試電纜應(yīng)保持清潔，以保證被測(cè)件接觸良好，夾具簧片調(diào)整至適當(dāng)?shù)乃删o程度.</p><div

style="text-indent:25px">LCR電橋使用中注意讀數(shù)及測(cè)量條件顯示:1.儀器的6位顯示不一定全部是有效顯示，在某些測(cè)量中測(cè)量數(shù)據(jù)的未尾值可能跳動(dòng)較大，應(yīng)舍去這些跳動(dòng)數(shù)值，讀取其穩(wěn)定值。2.一般使用自動(dòng)量程進(jìn)行測(cè)量，以保證選擇到正確的量程，操作到手動(dòng)方式可以觀察實(shí)際工作量程。應(yīng)用于同批同種測(cè)量元件的批量測(cè)試時(shí)，可以選擇量程鎖定模式工作。3.串--并聯(lián)指示:雖然電橋具有顯示串聯(lián)或并聯(lián)等效值的選擇性，但在不利的Q值情況下，用上述兩種方式均不可能獲得基本準(zhǔn)確度。當(dāng)需要改動(dòng)某一顯示方式以便提高基本準(zhǔn)確度時(shí)，電橋通過下標(biāo)s表示串聯(lián)，下標(biāo)p表示并聯(lián)。4.頻率提示:200μF～2000μF的電容，200H～2000H的電感，測(cè)量頻率在100Hz只能獲得基本準(zhǔn)確度。同樣，200pF～2nF的電容和200μH～2mH的電感，只有在1KHz測(cè)量頻率上才能獲得基本準(zhǔn)確度，因此獲得極好測(cè)試性能，應(yīng)選擇更合適的測(cè)試頻率。</p><p

style="text-indent:25px">用LCR測(cè)試儀來測(cè)量零部件的參數(shù)時(shí)，其關(guān)鍵問題在于測(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)。一般來說，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。深圳市展榮新精密電子有限公司專業(yè)從事電子變壓器、電容電阻等各類元器件測(cè)試儀等領(lǐng)域。安徽臺(tái)式lcr電橋</p><p
