智(zhi)能(neng)(neng)(neng)電(dian)阻(zu)具有(you)(you)更高(gao)(gao)的精(jing)度(du)(du)和(he)(he)穩定性(xing)(xing)。傳統的電(dian)阻(zu)測(ce)(ce)試儀器往往受到環境因(yin)素的影響(xiang)，導致測(ce)(ce)試結(jie)果(guo)的不準確。而智(zhi)能(neng)(neng)(neng)電(dian)阻(zu)通過內置(zhi)的智(zhi)能(neng)(neng)(neng)芯片和(he)(he)傳感器，可以(yi)實時監測(ce)(ce)環境溫度(du)(du)、濕度(du)(du)等因(yin)素，并自動進行校準，從而提(ti)(ti)高(gao)(gao)測(ce)(ce)試的精(jing)度(du)(du)和(he)(he)穩定性(xing)(xing)。這(zhe)將提(ti)(ti)高(gao)(gao)電(dian)子產品(pin)的質量和(he)(he)可靠性(xing)(xing)，滿足市場(chang)對產品(pin)的需(xu)(xu)求(qiu)。智(zhi)能(neng)(neng)(neng)電(dian)阻(zu)具有(you)(you)更高(gao)(gao)的自動化程度(du)(du)。傳統的電(dian)阻(zu)測(ce)(ce)試需(xu)(xu)要人工(gong)操作，耗時耗力且容易(yi)出錯。而智(zhi)能(neng)(neng)(neng)電(dian)阻(zu)可以(yi)通過與測(ce)(ce)試設(she)備的連接，實現(xian)自動化測(ce)(ce)試。只需(xu)(xu)設(she)置(zhi)測(ce)(ce)試參數，智(zhi)能(neng)(neng)(neng)電(dian)阻(zu)就能(neng)(neng)(neng)自動完成測(ce)(ce)試，并將測(ce)(ce)試結(jie)果(guo)傳輸給設(she)備或計算機進行分析。這(zhe)不僅提(ti)(ti)高(gao)(gao)了測(ce)(ce)試的效(xiao)率，還減(jian)少了人為因(yin)素對測(ce)(ce)試結(jie)果(guo)的影響(xiang)，提(ti)(ti)高(gao)(gao)了測(ce)(ce)試的準確性(xing)(xing)。產生離子遷移的原(yuan)因(yin)，是當絕緣體兩端的金屬之間有(you)(you)直(zhi)流(liu)電(dian)場(chang)時，這(zhe)兩邊的金屬就成為兩個電(dian)極。廣東SIR和(he)(he)CAF電(dian)阻(zu)測(ce)(ce)試設(she)備
