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

(1)可以兩個不同的測試頻率下?lián)p耗因子的變化性來決定，若頻率升高而損耗增加，則應(yīng)選用串聯(lián)等效電路若頻率升高而損耗減小，則應(yīng)選用并聯(lián)等效電路。對于電感來說，情況正好與電容相反。實(shí)際中器件的D 不可能與頻率完全成正比關(guān)系，其可能有并聯(lián)成分，也可能有串聯(lián)成分，應(yīng)看何種成分占主導(dǎo)。(2)根據(jù)元件的使用情況來判定。如用于信號耦合電容，則優(yōu)先選擇串聯(lián)方式，旁路或并聯(lián)諧振則使用并聯(lián)等效電路。習(xí)慣上說低阻抗元件用串聯(lián)，從數(shù)值上說阻抗小于100歐姆一定用串聯(lián)，大于10千歐用并聯(lián)，(100歐姆-10千歐)根據(jù)實(shí)際情況選擇。根據(jù)LCR數(shù)字電橋測量流過被測器件的電流(I)、電壓(v
