（2）對可能感應(yīng)出高壓電的設(shè)備,必須消除這種可能性后,才能進(jìn)行測量。 </p> <p> （3）被測物表面要清潔,減少接觸電阻,確保測量結(jié)果的正確性。 </p> <p> （4）測量前要檢查兆歐表是否處于正常工作狀態(tài),主要檢查其“0”和“∞”兩點。即搖動手柄,使電機(jī)達(dá)到額定轉(zhuǎn)速,兆歐表在短路時應(yīng)指在“0”位置,開路時應(yīng)指在“∞”位置。 </p> <p> （5）兆歐表 [1] 使用時應(yīng)放在平穩(wěn)、牢固的地方,且遠(yuǎn)離大的外電流導(dǎo)體和外磁場。 METRAHIT 27I數(shù)字絕緣電阻測試儀怎么樣？江蘇程控絕緣電阻測試儀哪種好</p><p style="text-indent:25px">表面絕緣電阻測試儀_深圳茂迪。江蘇絕緣電阻測試儀 mi2124價格</p><p> 用絕緣電阻測試儀測量絕緣電阻時，有哪些因素會造成測量數(shù)據(jù)不準(zhǔn)確，為什么？ </p> <p> A）電池電壓不足。電池電壓欠壓過低，造成電路不能正常工作，所以測出的讀數(shù)是不準(zhǔn)確的。 </p> <p> B）測試線接法不正確。誤將"L"、"G"、"E"三端接線接錯，或?qū)?G"、"L"連線"G"、"E"連線接在被測試品兩端。 </p> <p> C） "G"端連線未接。被測試品由于受污染潮濕等因素造成電流泄漏引起的誤差，造成測試不準(zhǔn)確，此時必須接好"G"端連線防止泄漏電流引起誤差。 </p> <p> D）干擾過大。如果被測試品受環(huán)境電磁干擾過大，造成儀表讀數(shù)跳動?；蛑羔樆蝿?。造成讀數(shù)不準(zhǔn)確。 </p> <p> E）人為讀數(shù)錯誤。在用指針式絕緣電阻測試儀測量時，由于人為視角誤差或標(biāo)度尺誤差造成示值不準(zhǔn)確。 </p> <p> F）儀表誤差。儀表本身誤差過大，需要重新校對。江蘇絕緣電阻測試儀 mi2124價格</p><p>
