將干電(dian)(dian)(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源，采(cai)用DC/DC變換技(ji)術提升至(zhi)所(suo)需的直流(liu)高(gao)壓(ya)電(dian)(dian)(dian)(dian)(dian)源100V，250V，500V，1000V，……5000V，10kV，且通(tong)過(guo)自穩壓(ya)技(ji)術使其(qi)穩定，由測(ce)試端鈕輸出。電(dian)(dian)(dian)(dian)(dian)子式電(dian)(dian)(dian)(dian)(dian)阻表自動產(chan)(chan)生(sheng)一(yi)(yi)個所(suo)需的直流(liu)電(dian)(dian)(dian)(dian)(dian)壓(ya)值，在被測(ce)試品上產(chan)(chan)生(sheng)一(yi)(yi)個泄漏(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)，通(tong)過(guo)泄漏(lou)電(dian)(dian)(dian)(dian)(dian)流(liu)大小，經(jing)過(guo)電(dian)(dian)(dian)(dian)(dian)路換算，得出一(yi)(yi)個絕緣電(dian)(dian)(dian)(dian)(dian)阻。
電動(dong)絕緣電阻測試儀表與(yu)手搖(yao)表的區別：
①電動絕緣電阻測試(shi)儀：每塊(kuai)表有2個或2個以(yi)上的額(e)定電壓；
手搖表：只有一個。
②電(dian)(dian)動絕緣電(dian)(dian)阻測試(shi)儀(yi)：穩(wen)定自身產生(sheng)個(ge)額定電(dian)(dian)壓(ya)，輸出電(dian)(dian)壓(ya)穩(wen)定；
手搖式(shi)：120轉(zhuan)/分(fen)轉(zhuan)速人工產生一個額定電(dian)壓(ya)，輸(shu)出電(dian)壓(ya)在轉(zhuan)速相對穩定時穩定。）
③電(dian)(dian)動絕緣(yuan)電(dian)(dian)阻測試(shi)儀：測試(shi)方便(bian)，精度(du)高(gao)，自動化程(cheng)度(du)高(gao)；
手搖式：人為造成精(jing)度誤差大，操作不(bu)方便
④電動絕(jue)緣(yuan)電阻測(ce)試儀：測(ce)各種絕(jue)緣(yuan)參數(shu)R15s、R60s、R10min、吸收比(bi)、化指數(shu)時很(hen)方便；
手(shou)(shou)搖式(shi)：測(ce)吸收比要手(shou)(shou)搖1分鐘(zhong)，測(ce)化指數要手(shou)(shou)搖10分鐘(zhong)；
⑤電(dian)動絕緣(yuan)電(dian)阻測試(shi)儀：不怕(pa)短路測試(shi)，不怕(pa)被測試(shi)品電(dian)流(liu)反擊，自動對被測試(shi)品放電(dian)；
手搖式：不具備此功能。
