AD采樣，數(shù)字信號(hào)處理技術(shù)，分辨力達(dá)到0.01μΩ，是目前國內(nèi)能達(dá)到0.01μΩ分辨力且十分穩(wěn)定的接觸電阻測試儀，性能超過了進(jìn)口大電流微歐計(jì)。<br/>4、智能化：進(jìn)口高性能CPU，測量時(shí)系統(tǒng)根據(jù)信號(hào)大小自動(dòng)切換量程，確保測試準(zhǔn)確度。過溫保護(hù)電路能夠在儀器超過設(shè)定溫度時(shí)自動(dòng)停止輸出電流，確保儀器安全使用。<br/>5、高品質(zhì)：關(guān)鍵部件全部采用進(jìn)口元件，通過巧妙設(shè)計(jì)的溫度補(bǔ)償電路有效的消除環(huán)境溫度對測量結(jié)果的影響，接插件的使用增強(qiáng)了抗振性能。<br/>6、功能強(qiáng)大：電流流50A、100A中自由選擇，測試時(shí)間在5s~599s內(nèi)任意設(shè)定，克服其他同類儀器無法設(shè)定測量時(shí)間或連續(xù)工作時(shí)間過短的缺陷，遠(yuǎn)遠(yuǎn)超過其他同類儀器的性能。<br/>7、人機(jī)界面友好：旋轉(zhuǎn)鼠標(biāo)輸入數(shù)據(jù)，方便快捷，自主設(shè)置儀器日期、時(shí)間，實(shí)時(shí)保存測量數(shù)據(jù)，即時(shí)打印測量結(jié)果。</p><p
