用絕緣電阻測(cè)試儀測(cè)量絕緣電阻時(shí)，有哪些因素會(huì)造成測(cè)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(cè)出的讀數(shù)是不準(zhǔn)確的。 </p> <p> B）測(cè)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(cè)試品兩端。 </p> <p> C） "G"端連線未接。被測(cè)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(cè)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，江西絕緣電阻測(cè)試儀搖表。如果被測(cè)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。 </p> <p>

絕緣電阻表一般采用自動(dòng)校準(zhǔn)技術(shù)，除指明可以更換的部件外，所以不要隨意更換，以免技術(shù)指標(biāo)發(fā)生偏差。一、一般的維修保養(yǎng) 1)定期用濕布及中性的清潔劑清理儀表的外殼，不要用研磨劑或溶劑。端子上和表筆端子上污垢會(huì)影響讀數(shù)，可用清潔劑清理每個(gè)端子上的污物。 2)不使用時(shí)，按power鍵關(guān)閉，長(zhǎng)期用應(yīng)取出電池。 3)存放儀表應(yīng)避免潮濕，高溫和強(qiáng)磁場(chǎng)。二、更換電池 1)按power鍵關(guān)閉電源，并從端子上把表筆或測(cè)試導(dǎo)線拆下，使測(cè)試導(dǎo)線與被測(cè)電路完全斷開。 2)將電池蓋的兩顆螺絲拆下，并把電池蓋取下。 3)從電池盒上把電池取下。 4)用6節(jié)aa(am3/lr6)新電池(標(biāo)準(zhǔn)容量約2450mah)換上。 5)把電池蓋合上，裝上兩顆螺絲。內(nèi)蒙古絕緣電阻測(cè)試儀兆歐表檢測(cè)機(jī)電設(shè)備用絕緣電阻測(cè)試儀要求的工作電壓和測(cè)試精度。</p><div style="width:100%;text-align:

style="text-indent:25px">智能雙顯絕緣電阻測(cè)試儀。江西絕緣電阻測(cè)試儀搖表</p><p> 怎樣選用數(shù)字兆歐表？兆歐表的選用，主要是選擇其電壓及測(cè)量范圍，高壓電氣設(shè)備需使用電壓高的兆歐表。低壓電氣設(shè)備需使用電壓低的兆歐表。一般選擇原則是： 500伏以下的電氣設(shè)備選用500~1000伏的兆歐表；瓷瓶、母線、刀閘應(yīng)選用2500伏以上的兆歐表。數(shù)字兆歐表測(cè)量范圍的選擇原則是：要使測(cè)量范圍適應(yīng)被測(cè)絕緣電阻的數(shù)值免讀數(shù)時(shí)產(chǎn)生較大的誤差。如有些兆歐表的讀數(shù)不是從零開始，而是從1兆歐或2兆歐開始。這種表就不適宜用于測(cè)定處在潮濕環(huán)境中的低壓電氣設(shè)備的絕緣電阻。因?yàn)檫@種設(shè)備的絕緣電阻有有可能小于1兆歐，使儀表得不到讀數(shù)，容易誤認(rèn)為絕緣電阻為零，而得出錯(cuò)誤結(jié)論
