通過“MΩ/GΩ”表讀取電阻值。秒表在高壓輸出后的15秒、60秒、每隔60秒報時，便于操作者記錄。關(guān)于吸收比、極化指數(shù)的計算公式為：吸收比=R60s/R15s，即第60秒的電阻讀數(shù)÷第15秒的電阻讀數(shù)。極化指數(shù)=R10min/R1min，即第10分鐘的電阻讀數(shù)÷第1分鐘的電阻讀數(shù)。 9、測試電壓退出將“高壓控制”按鈕退出，這時“kV”表就會緩慢回零，數(shù)字秒表也會退出顯示。如果“kV”表不緩慢回零，則應(yīng)以帶電阻的放***放電。

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。因為這種設(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

幾乎所有的絕緣測試儀都采用直流電壓作為激勵，所以兆歐表校準(zhǔn)器的交流要求很少。許多兆歐表為兩端設(shè)備，它提供一個電壓，并測量由被測設(shè)備所決定的電流。量程達(dá)到1TΩ 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，***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。浙江智能絕緣電阻測試儀哪個品牌好</p><p>
