絕緣漆膜表面電阻率測試儀根據(ju)歐姆定(ding)律，被(bei)測(ce)(ce)(ce)(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)Rx等于(yu)施加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V除以(yi)(yi)通過的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)I。傳統的(de)(de)(de)(de)(de)高(gao)(gao)(gao)(gao)阻(zu)(zu)計的(de)(de)(de)(de)(de)工作原理是(shi)(shi)(shi)測(ce)(ce)(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V固定(ding)，通過測(ce)(ce)(ce)(ce)量(liang)流(liu)(liu)過取樣(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)I來得到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值(zhi)(zhi)。從歐姆定(ding)律可以(yi)(yi)看出，由于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)I是(shi)(shi)(shi)與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)成(cheng)反比，而不(bu)是(shi)(shi)(shi)成(cheng)正比，所(suo)以(yi)(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)顯示值(zhi)(zhi)是(shi)(shi)(shi)非(fei)線性的(de)(de)(de)(de)(de)，即(ji)(ji)(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)無窮大(da)時，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)為(wei)零(ling)，即(ji)(ji)(ji)表(biao)頭(tou)的(de)(de)(de)(de)(de)零(ling)位處是(shi)(shi)(shi)∞，其(qi)附近(jin)的(de)(de)(de)(de)(de)刻(ke)度非(fei)常密，分(fen)辨率很(hen)低。整(zheng)個刻(ke)度是(shi)(shi)(shi)非(fei)線性的(de)(de)(de)(de)(de)。又由于(yu)測(ce)(ce)(ce)(ce)量(liang)不(bu)同的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)時，其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V也會有(you)些變(bian)化(hua)，所(suo)以(yi)(yi)普(pu)通的(de)(de)(de)(de)(de)高(gao)(gao)(gao)(gao)阻(zu)(zu)計是(shi)(shi)(shi)精度差、分(fen)辨率低。本儀器是(shi)(shi)(shi)同時測(ce)(ce)(ce)(ce)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)兩(liang)端(duan)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V和流(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)I，通過內部的(de)(de)(de)(de)(de)大(da)規模集(ji)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路完成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)除以(yi)(yi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)計算(suan)，然后把所(suo)得到(dao)的(de)(de)(de)(de)(de)結(jie)果經過A/D轉換后以(yi)(yi)數(shu)字顯示出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值(zhi)(zhi)，即(ji)(ji)(ji)便是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)兩(liang)端(duan)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V和流(liu)(liu)過電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)I是(shi)(shi)(shi)同時變(bian)化(hua)，其(qi)顯示的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)值(zhi)(zhi)不(bu)象(xiang)普(pu)通高(gao)(gao)(gao)(gao)阻(zu)(zu)計那樣(yang)因被(bei)測(ce)(ce)(ce)(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)V的(de)(de)(de)(de)(de)變(bian)化(hua)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)Ｉ的(de)(de)(de)(de)(de)變(bian)化(hua)而變(bian)，所(suo)以(yi)(yi)，即(ji)(ji)(ji)使(shi)測(ce)(ce)(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)、被(bei)測(ce)(ce)(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)等發生(sheng)變(bian)化(hua)對其(qi)結(jie)果影響不(bu)大(da)，其(qi)測(ce)(ce)(ce)(ce)量(liang)精度很(hen)高(gao)(gao)(gao)(gao)()，從理論上講(jiang)其(qi)誤差可以(yi)(yi)做到(dao)零(ling)，而實際誤差可以(yi)(yi)做到(dao)千(qian)分(fen)之幾(ji)或(huo)萬分(fen)之幾(ji)。
