5、測試儀使用時(shí)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。絕緣電阻測量儀注意 1、在測量電阻前，待測電路必須完全放電，并且與電源電路完全隔離。 2、如測試筆或電源適配器破損需更換，必須換上同型號和相同電氣規(guī)格的測試筆或電源適配器。 3、電池指示器批示電能耗盡時(shí)，不要使用儀器。若長時(shí)間不使用儀器，請將電池取出后存放。 4，安徽mit481絕緣電阻測試儀作業(yè)指導(dǎo)書、不要在高溫、高濕、易燃、易爆和強(qiáng)電磁場環(huán)境中存放或使用本儀器。 5、請使用濕布或清潔劑來清潔儀器外殼，請勿使用磨擦物或溶劑。 6、儀器潮濕時(shí)，請先干燥后存儲。

用絕緣電阻測試儀測量絕緣電阻時(shí)，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(cuò)，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(shí)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(cuò)誤。在用指針式絕緣電阻測試儀測量時(shí)，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。安徽mit481絕緣電阻測試儀作業(yè)指導(dǎo)書</p><p
