style="text-indent:25px">LCR電橋使用中注意讀數(shù)及測量條件顯示:1.儀器的6位顯示不一定全部是有效顯示，在某些測量中測量數(shù)據(jù)的未尾值可能跳動較大，應(yīng)舍去這些跳動數(shù)值，讀取其穩(wěn)定值。2.一般使用自動量程進(jìn)行測量，以保證選擇到正確的量程，操作到手動方式可以觀察實(shí)際工作量程。應(yīng)用于同批同種測量元件的批量測試時，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)需要改動某一顯示方式以便提高基本準(zhǔn)確度時，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測量頻率上才能獲得基本準(zhǔn)確度，因此獲得極好測試性能，應(yīng)選擇更合適的測試頻率。</p><p

= V1*Rr/V2。因為運(yùn)算放大器虛地功能的引入，使這種測量方法的精度和抗干擾能力產(chǎn)生了質(zhì)的飛躍。當(dāng)然，以上只是一個比較抽象化的原理模型，真正的產(chǎn)品要復(fù)雜的多。正確合理的使用LCR數(shù)字電橋，會極大的提高LCR數(shù)字電橋的使用壽命。</p><div style="width:100%;text-align:
