的詳細(xì)介紹
QJ83-1量程比QJ83小一檔（從2Ω開始小分辨力100μΩ）更適合中、高阻值的測量。是我廠真正以惠斯登電橋線路為基礎(chǔ),用精密合金繞線電阻為基準(zhǔn)的數(shù)字電橋。它具有數(shù)字萬用表同樣簡便、快速、醒目的特點(diǎn)，還保持了惠斯登電橋準(zhǔn)確、穩(wěn)定、可靠的優(yōu)點(diǎn)。使用方便不需要調(diào)零、不用對標(biāo)準(zhǔn)，測試快捷，是工礦企業(yè)、科研單位、計量部門對各類直流電阻作精密測量的佳選擇。
準(zhǔn)確優(yōu)于同等級直流電阻電橋外接檢流計才能達(dá)到的準(zhǔn)確度。
簡便只要接上被測電阻選好量程，測試過程不再用手工操作。
快速采樣時間為0.4秒，一般在數(shù)秒內(nèi)即可顯示穩(wěn)定數(shù)據(jù)。
醒目采用200mm大數(shù)顯，字跡清晰，一目了然。
穩(wěn)定主要基準(zhǔn)電阻采用精密錳銅合金線繞制。穩(wěn)定性優(yōu)于0.02%。
可靠主要元器件采用進(jìn)口原裝，并經(jīng)特殊配選老化。
