style="text-indent:25px">LCR電橋列表掃描：鑒于元件對頻率、電平、直流偏置電壓、直流偏置電流的相關(guān)性。即對多點頻率（或電平、偏壓、偏流）掃描測量，并將測量值同時顯示，還可對測試值進(jìn)行比較判別。偏流的列表掃描需與同惠的電感偏流源配合使用。測試端配置：傳統(tǒng)的LCR 數(shù)字電橋提供了五端測試端配置。這種配置有效解決了引線電阻對測試結(jié)果的影響及測試端子對地的分布電容。然而，五端配置阻抗測試下限為10mΩ，且不能解決測試線間相互電磁藕合的影響，表現(xiàn)為低阻抗測試時使用開而文測試電纜時引線位置的移動便會造成測試結(jié)果的變化。TH2828/A/S 的四端對配置方法不僅阻抗測試下限達(dá)到1mΩ，且有效解決測試線間電磁耦合的影響。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。江西lcr自動測量儀</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。如果使用在一個夾子上有2個相互絕緣的電極的開耳芬夾子，那么用2個夾子可以容易地進(jìn)行4個端子的連接。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，其特點是不會受到溫差電動勢的影響。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。安徽電橋lcr</p><p
