style="text-indent:25px">LCR與試樣的四端子法:設(shè)置**的電壓檢測(cè)電纜，以消除由于測(cè)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(cè)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(duì)法:對(duì)于交流阻抗的測(cè)量，與直流測(cè)量不同，其特點(diǎn)是不會(huì)受到溫差電動(dòng)勢(shì)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(cè)量的頻率越高，要想測(cè)量低阻抗就越困難。對(duì)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。中山經(jīng)濟(jì)型lcr數(shù)字電橋精度高、量程寬、速度快、穩(wěn)定性好是LCR電橋的特點(diǎn)。</p><div

style="text-indent:25px">現(xiàn)在說幾個(gè)LCR數(shù)字電橋日常保養(yǎng)的技巧：請(qǐng)不要在多塵、震動(dòng)、強(qiáng)光直射等不佳環(huán)境下使用儀器。盡管儀器已針對(duì)不佳雜訊( 特別是交流電源噪聲) 的影響做了特殊處理，但仍應(yīng)盡可能在低噪聲的環(huán)境中使用。如果無法避免，請(qǐng)為本儀器安裝電源濾波器。LCR數(shù)字電橋長(zhǎng)期不用，請(qǐng)用原始包裝或先包密封塑料袋再用紙箱包裝，儲(chǔ)存在溫度為-10℃ ～40℃ 、濕度≤85%RH 的通風(fēng)室內(nèi)。若被測(cè)件為電容器時(shí)，盡管儀器具有專門設(shè)計(jì)的抗沖擊電路，通過將被測(cè)電容與信號(hào)源測(cè)試部分相隔離和吸收回路，使得由于電容帶電對(duì)儀器的破壞性極大降低。但從儀器的可靠性和安全性角度來講，應(yīng)先將被測(cè)電容器的余電放干凈，再進(jìn)行測(cè)試。</p><p 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。LCR數(shù)字電橋在工廠、院校、研究所、計(jì)量質(zhì)檢部門等場(chǎng)所已經(jīng)開始發(fā)揮獨(dú)特的優(yōu)勢(shì)。</p><div
