style="text-indent:25px">LCR測(cè)試儀一般用于測(cè)試電感和電容。測(cè)量步驟如下：1、設(shè)置測(cè)試頻率，2、測(cè)試電壓或者電流水平，3、選擇測(cè)試參數(shù)，比如Z、Q、LS（串聯(lián)電感）、LP（并聯(lián)電感）、CS（串聯(lián)電容）、CP（并聯(lián)電容）、D等，4、儀器校準(zhǔn)，校準(zhǔn)主要進(jìn)行開(kāi)路、短路校準(zhǔn)，**的儀器要進(jìn)行負(fù)載校準(zhǔn)，5、選擇測(cè)試夾具，6、夾具補(bǔ)償，7、將DUT放在夾具上開(kāi)始測(cè)試。以上就是一個(gè)完整的步驟了，如果想對(duì)測(cè)試儀有更多了解可以關(guān)注深圳市展榮新精密電子有限公司，專業(yè)從事電子變壓器、電感線圈、電容電阻等各類元器件測(cè)試儀之自主研發(fā)、制造和銷售。現(xiàn)有的主要產(chǎn)品—電子變壓器綜合測(cè)試系統(tǒng)、精密LCR數(shù)字電橋和直流微電阻表等，并代理國(guó)內(nèi)外**品牌的測(cè)量?jī)x表。</p><p style="text-indent:25px">LCR數(shù)字電橋操作面板都有“串聯(lián)”和“并聯(lián)”按鍵供用戶選擇，這串聯(lián)和并聯(lián)不是物理連結(jié)，而是內(nèi)在計(jì)算模式的改變，以改變計(jì)算模式得到理想的測(cè)試精度。理論上電感正弦波激勵(lì)響應(yīng)電壓超前電流90度，電容電壓落后電流90度。實(shí)際測(cè)量中由于銅阻和各種損耗的存在，超前或落后都小于90度，這種損耗在測(cè)量中以副參數(shù)出現(xiàn)，電感損失角的正切值的倒數(shù)稱品質(zhì)因素Q值。同樣電容損失角的正切值稱損耗因子DF。LCR數(shù)字電橋進(jìn)行高精度量化，要建立適當(dāng)?shù)臄?shù)學(xué)模型，經(jīng)過(guò)一些數(shù)學(xué)運(yùn)算，得到各種參數(shù)值。在整個(gè)過(guò)程中，把損耗的影響用電阻等效和電感或電容串并聯(lián)。對(duì)于LCR數(shù)字電橋的使用來(lái)說(shuō),正確的選擇所需要的電阻頻率很重要.</p><div
