用絕緣電阻測試儀測量絕緣電阻時(shí)，有哪些因素會(huì)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"，湖南絕緣子絕緣電阻測試儀、"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，湖南絕緣子絕緣電阻測試儀，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(dòng)?；蛑羔樆蝿?dòng)。造成讀數(shù)不準(zhǔn)確，湖南絕緣子絕緣電阻測試儀。 </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>
