:蕪湖2098-DSD-020-DN羅克韋爾伺服驅(qū)動器哪里好使用前應(yīng)將檢流計(jì)的鎖扣打開，調(diào)節(jié)調(diào)零器確保指針指在零位。然后使用萬用表的歐姆擋估計(jì)待測電阻的大致數(shù)值。根據(jù)萬用表測得的電阻值選擇適當(dāng)?shù)谋壤?，使比較臂的四個(gè)電阻都能被充分利用，提高測量準(zhǔn)確度。，用萬用表測量的待測電阻估計(jì)值約為幾Ω時(shí)，應(yīng)選用0.001的比例臂；待測電阻估計(jì)值為幾十歐姆時(shí)，應(yīng)選用0.01的比例臂；待測電阻為幾百歐姆，應(yīng)選用0.1的比例臂；待測電阻為幾千歐姆時(shí)，應(yīng)選用1的比例臂。測量中在接入待測電阻時(shí)，應(yīng)采用較粗較短的導(dǎo)線，并將接頭擰緊，以減小接線電阻和接觸電阻。
