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。LCR數(shù)字電橋可自動(dòng)置于電感、電容測(cè)量檔，并聯(lián)等效及1KHz頻率狀態(tài)。成都lcr檢測(cè)儀器</p><p
