style="text-indent:25px">一般地，LCR數(shù)字電橋用于三個(gè)方面的目的：首先精確評(píng)價(jià)元件的性能，保證元件在使用條件下滿足要求。為對元件作出精確的評(píng)價(jià)，需要儀器能提供高準(zhǔn)確度、強(qiáng)大的功能，能對元件與多種條件的相關(guān)性作出準(zhǔn)確的評(píng)價(jià)。如新元件的研究與開發(fā)，計(jì)量檢定部門作檢測、量值傳遞等。其次元件生產(chǎn)線快速檢測或進(jìn)貨檢驗(yàn)這種目的對于儀器的測量條件是特定的。如提供快速的分選以提高效率，特定的頻率、電平及其它一些所需要的功能等。再而需了解元件的一般性能LCR，選擇LCR數(shù)字電橋的目的且無快速的分選要求。LCR 數(shù)字電橋型號(hào)的劃分也基本按照這三種要求決定。</p><p style="text-indent:25px">LCR與試樣的四端子法:設(shè)置**的電壓檢測電纜，以消除由于測試電纜的串聯(lián)阻抗所引起的電壓降和接觸電阻的影響等，是一種減少低阻抗零部件的測量誤差的方法。需要考慮由于電纜之間的互電感（M）所產(chǎn)生的影響。如果使用在一個(gè)夾子上有2個(gè)相互絕緣的電極的開耳芬夾子，那么用2個(gè)夾子可以容易地進(jìn)行4個(gè)端子的連接。LCR與試樣的四端子對法:對于交流阻抗的測量，與直流測量不同，其特點(diǎn)是不會(huì)受到溫差電動(dòng)勢的影響。但是，由于電流電纜與電壓電纜之間的電磁感應(yīng)，測量的頻率越高，要想測量低阻抗就越困難。對于這個(gè)問題，可以利用電纜的屏蔽層，使電流的去路和歸路相互重疊，以抑制磁通量的產(chǎn)生，由此來減少由于電磁感應(yīng)所引起的殘留阻抗。選擇LCR數(shù)字電橋關(guān)心的主要方面：測量準(zhǔn)確度，測試信號(hào)頻率與電平，儀器價(jià)位。</p><div

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(jì)算Zx。LCR測試儀提高精度的方法是: 1,Hp,Lp,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,使用Gurard與Cable構(gòu)建地平面中斷信號(hào)線間的電場連接，雖然會(huì)增加信號(hào)線的對地電容（對地電容不影響測試結(jié)果），但是會(huì)減少信號(hào)線的互容。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(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的電壓測量。LCR數(shù)字電橋使用內(nèi)部/外部直流偏置，結(jié)合各種掃描測試功能，可以精確地分析磁性材料、電感器件的性能。珠海lcr數(shù)字電橋</p><p style="text-indent:25px">在使用LCR數(shù)字電橋時(shí)需要注意環(huán)境的濕度與溫度的把握。珠海lcr數(shù)字電橋</p><p style="text-indent:25px">LCR數(shù)字電橋的功能還有：開路OPEN/短路SHORT清“0”：在測試時(shí)，測試夾具也存在許多分布參數(shù)，這些均會(huì)影響測試結(jié)果的準(zhǔn)確性。解決此問題的方法便是進(jìn)行開路OPEN/短路SHORT清“0”。首先將測試夾具的分布參數(shù)看作**形網(wǎng)絡(luò)，其存在的分布參數(shù)綜合為集中參數(shù)分析，a）測試引線引起的參數(shù)，該參數(shù)使用短路清“0”消除；b）測試端間的分布參數(shù)，該參數(shù)使用開路清“0”消除。負(fù)載校準(zhǔn)：負(fù)載校準(zhǔn)是一種上等的儀器校準(zhǔn)方法?？梢允箖x器在高于儀器原有準(zhǔn)確度的基礎(chǔ)上測量元件，主要使用于下述兩種情況：a）當(dāng)有更準(zhǔn)確的元件并需對同規(guī)格元件進(jìn)行更高準(zhǔn)確度的測量；b）統(tǒng)一現(xiàn)場所有LCR
