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)字兆歐表測量范圍的選擇原則是：要使測量范圍適應(yīng)被測絕緣電阻的數(shù)值免讀數(shù)時產(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，而得出錯誤結(jié)論

以及更高的兆歐表通常具有第三個端子，稱為保護(hù)端（Guard），對于消除泄漏通路以及被測未知電阻Rx的并聯(lián)元件非常有用。保護(hù)端的目的是消除可能會產(chǎn)生的泄漏電流來選擇性地將輸出寄生電阻性元件的影響減小為零。 </p> <p> 絕緣測試儀，通常被稱為數(shù)字兆歐表或高阻計(jì)，***用于測量發(fā)電機(jī)、馬達(dá)、電源變壓器、配線、電器和其它電氣裝置（如控制、信號、通信和電源的電纜）的絕緣電阻。絕緣電阻表使用方法。湖南絕緣電阻測試儀1508</p><p style="text-indent:25px">絕緣電阻測試儀的型號選擇-深圳茂迪。廣西表面絕緣電阻測試儀使用方法</p><p style="text-indent:25px">經(jīng)過幾十年的發(fā)展，我國已經(jīng)成為世界上第二大儀器儀表制造國，儀器儀表產(chǎn)業(yè)形成了一定的規(guī)模，儀器儀表產(chǎn)品也比較豐富。儀器儀表在工業(yè)生產(chǎn)過程中扮演著重要的角色，用到各種各樣的儀器儀表，如電能質(zhì)量分析儀，功率分析儀，亮度計(jì)，色差儀等為工業(yè)的檢驗(yàn)、測量和計(jì)量提供技術(shù)支撐。目前我國一般經(jīng)營項(xiàng)目是：儀器儀表、通訊器材、機(jī)械設(shè)備、五金工具的購銷、技術(shù)維護(hù)、信息咨詢；國內(nèi)貿(mào)易；貨物與技術(shù)的進(jìn)出口業(yè)務(wù)。（法律、行政法規(guī)、國**決定禁止的項(xiàng)目除外，限制的項(xiàng)目須取得許可后方可經(jīng)營），許可經(jīng)營項(xiàng)目是：儀器儀表、通訊器材、機(jī)械設(shè)備、五金工具的安裝、維修。產(chǎn)品，主要集中在中低檔市場，而市場則主要被國外品牌所占據(jù)。在某些領(lǐng)域，國產(chǎn)產(chǎn)品甚至是空白，這就需要未來我國儀器儀表向市場進(jìn)軍，擴(kuò)大產(chǎn)品占比。貿(mào)易專業(yè)化發(fā)展是中國儀器儀表產(chǎn)業(yè)的又一發(fā)展趨勢，隨著科技水平的提高，儀器儀表產(chǎn)品不僅用在日常的測量、調(diào)節(jié)、測溫、顯示等設(shè)備中，而且開始運(yùn)用在不同的領(lǐng)域之中。廣西表面絕緣電阻測試儀使用方法</p><p
