描述

電位器電路板維修的檢測(cè)。檢測(cè)電位器的活動(dòng)臂與電阻片的接觸是否良好。用萬(wàn)用表的歐姆檔測(cè)“1”、“2”(或“2”、“3”)兩端，將電位器的轉(zhuǎn)軸按逆時(shí)針?lè)较蛐两咏瓣P(guān)”的位置，這時(shí)電阻值越小越好。再順時(shí)針慢慢旋轉(zhuǎn)軸柄，電阻值應(yīng)逐漸增大，表頭中的指針應(yīng)平穩(wěn)移動(dòng)。當(dāng)軸柄旋至極端位置“3”時(shí)，阻值應(yīng)接近電位器的標(biāo)稱(chēng)值。如萬(wàn)用表的指針在電位器的軸柄轉(zhuǎn)動(dòng)過(guò)程中有跳動(dòng)現(xiàn)象，說(shuō)明活動(dòng)觸點(diǎn)有接觸不良的故障。
