style="text-indent:25px">對(duì)于LCR數(shù)字電橋的使用來說,正確的選擇所需要的電阻頻率很重要.云南lcr電橋表選擇</p><p style="text-indent:25px">用LCR測(cè)試儀來測(cè)量零部件的參數(shù)時(shí)，其關(guān)鍵問題在于測(cè)量誤差。首先是LCR測(cè)試儀本身的內(nèi)部誤差，還存在各種各樣的原因，而與試樣的連接所引起的誤差，就是其中之一。由于LCR測(cè)試儀的型號(hào)不同，可能的連接方法也會(huì)有區(qū)別，每種連接方法的各自特點(diǎn)。一般來說，連接方法越麻煩，越能準(zhǔn)確地進(jìn)行測(cè)量。二端子法:雖然連接容易，但是由于接觸電阻、連接電纜的串聯(lián)阻抗（r）、連接電纜以及端子之間的雜散電容（Cs）會(huì)引起較大的誤差，如果不是中等數(shù)量級(jí)的阻抗，那么測(cè)量誤差就會(huì)比較大。三端子法:對(duì)測(cè)試電纜和試樣進(jìn)行屏蔽，通過抑制雜散電容，減少對(duì)于高阻抗零部件的測(cè)量誤差。主要可用于測(cè)量較小的電容量。云南lcr電橋表選擇</p><p
