合成電阻的方法由于受到設(shè)計(jì)成本和尺寸規(guī)格的限制被排除在外。采用的是分立式高壓電阻器矩陣的方法，組成一個(gè)陣列，能夠提供500,000多種電阻值輸出。在這種校準(zhǔn)器中，有8個(gè)范圍的電阻值，覆蓋了10kΩ到10 GΩ的范圍，每個(gè)范圍均能提供4.5 位的穩(wěn)定輸出。 </p> <p> 收**適的高壓電阻器并將其集成到一個(gè)儀器內(nèi)又存在另一項(xiàng)挑戰(zhàn)。這就是與歐盟CE認(rèn)證的一項(xiàng)強(qiáng)制性要求《低電壓指令》相關(guān)的安全性標(biāo)準(zhǔn)挑戰(zhàn)。與儀器制造商相關(guān)的標(biāo)準(zhǔn)是EN 61010－測(cè)量、控制和實(shí)驗(yàn)室用電氣設(shè)備的安全要求。 </p> <p> 低電壓指令要求將校準(zhǔn)器電壓限制為1,000Vrms。那么如何校準(zhǔn)測(cè)試電壓高達(dá)5 kV 的兆歐表呢？這類(lèi)儀器具有更寬的動(dòng)態(tài)范圍，可測(cè)量高到10TΩ的電阻，并且提供了如上所述的保護(hù)端子，使其能夠準(zhǔn)確測(cè)量非常高的電阻值。幸運(yùn)的是，這樣的保護(hù)配置可以使其本身形成一個(gè)電阻倍增器，能夠有效地將一個(gè)已知電阻倍增為1000倍。同樣重要的是，由于倍增器是一個(gè)分立、隔離、**的設(shè)備，可以滿(mǎn)足倍增器所需的高電壓，它已經(jīng)不是《低電壓指令》所管轄的范圍。
