Test)接入電路時，放大器的負(fù)反饋配置自動使得OP輸入端虛地。Vx準(zhǔn)確測定DUT兩端電壓（DUT的Low電位是0），Vr與Rr測得DUT電流Ix，由此可計算Zx。LCR測試儀提高精度的方法是: 1,Hp,Lp，貴州lcr電橋系統(tǒng),Hc,Lc盡量接近DUT; 2,減小測試電流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，貴州lcr電橋系統(tǒng),使用Gurard與Cable構(gòu)建地平面中斷信號線間的電場連接，雖然會增加信號線的對地電容（對地電容不影響測試結(jié)果），但是會減少信號線的互容，貴州lcr電橋系統(tǒng)。Guard與Cable的對地寄生阻抗（Zhg,Zlg) 不影響測試結(jié)果，電橋平衡時Zlg的兩端電壓是0，流向Rr的電流不會被Zlg分流，Zhg的分流作用不影響Hp的電壓測量。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="貴州lcr電橋系統(tǒng)"

style="text-indent:25px">用LCR測試儀來測量零部件的參數(shù)時，其關(guān)鍵問題在于測量誤差。首先是LCR測試儀本身的內(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測試儀的型號不同，可能的連接方法也會有區(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）會引起較大的誤差，如果不是中等數(shù)量級的阻抗，那么測量誤差就會比較大。三端子法:對測試電纜和試樣進(jìn)行屏蔽，通過抑制雜散電容，減少對于高阻抗零部件的測量誤差。主要可用于測量較小的電容量。</p><div

插座上，另一端插入合適的電源插座上，搬動電橋左后方的船形開關(guān)，即使電橋通電。通電后，顯示器、量程及功能指示器隨之變亮。電橋可自動置于電感、電容測量檔，并聯(lián)等效及1KHz頻率狀態(tài)。正常情況下，內(nèi)部電路加電幾秒鐘后即能穩(wěn)定，便可進(jìn)行測量。被測元件的接入方法：1.通常徑向引線的元件可直接插入組合測試夾夾板內(nèi)，而接入特殊柔性引線的元件時，應(yīng)借助夾板離合器進(jìn)行，該離合裝置位于測試夾的正下方。2.接入軸向引線元件時，為避免扭折引線，可采用軸向轉(zhuǎn)接頭，先把這兩個配件分別插入測試夾的兩端，再將其間距調(diào)正到適合元件測量的位置，然后便將軸向引線元件插入兩端的配件夾內(nèi)。3.在軸向轉(zhuǎn)接頭必需相當(dāng)牢固定的場合，如在測量大量的同類元件時，需采用支撐板。</p></p><br
