描述

(1)測量電流或電壓時，有一檔或數(shù)檔無指示，其它檔指示正常.原因是鉗形電表的緊固開關(guān)螺絲松動，或是其分線開關(guān)上的連線被扭斷.這種故障最常見，開蓋后將斷線接好即可。

(2)電流檔讀數(shù)偏小，電壓檔讀數(shù)正常.其原因大多是因鉗口接觸不好，漏磁太多造成的，應(yīng)當(dāng)修正鉗口使其接觸良好.這種故障有時是由于繞組間短路所引起的，這時就比較麻煩，一般米說要重新按照原數(shù)據(jù)繞制，還須進行老化處理.

(3)電流電壓檔的讀數(shù)都偏低，這種現(xiàn)象在內(nèi)磁式鉗形電表上經(jīng)常發(fā)生.原因是磁鐵退磁，一般應(yīng)當(dāng)充磁解決，也可通過減小與表頭支路串聯(lián)的電阻值進行調(diào)整.

(4)其中某一檔讀數(shù)不準，應(yīng)當(dāng)調(diào)整相應(yīng)的電阻.

(5)電壓檔指示正常，電流檔全部沒有指示.應(yīng)用萬用表檢查初線開關(guān)和次級繞組，看是否有異?，F(xiàn)象.

(6)全部無指示.應(yīng)當(dāng)檢查整流二極管、表頭、開關(guān)，以及與鉗形表相連或有關(guān)的接線是否有斷處.
