²  计(ji)量功(gong)效：电(dian)能(neng)(neng)表(biao)可计(ji)量三相正、反(fan)向有(you)功(gong)电(dian)能(ne﷽ng)(neng)，反(fan)向电(dian)能(neng)(neng)按正向累计(ji)；

²  预支费办理功效：电(dian)(dian)(dian)能表(biao)可与PC机售电(dian)(dian)(dian)体系共同完(wan)成预支费办理功效。用(yong)户(hu)拔出开户(hu)卡，对电(dian)(dian)(dian)能表(biao)的(de)(de)报警电(dian)(dian)(💛dian)量(liang)(liang)、透(tou)支电(dian)(dian)(dian)量(liang)(liang)、限(xian)购电(dian)(dian)(dian)量(liang)(liang)、囤积电(dian)(dian)(dian)量(liang)(liang)、过(guo)载负(fu)荷等参(can)数(shu)停止(zhi)设置，并向电(dian)(dian)(dian)能表(biao)充值给(ji)负(fu)载通电(dian)(dian)(dian)；完(wan)成参(can)数(shu)设置后开户(h🤪u)卡即成为用(yong)户(hu)的(de)(de)购电(dian)(dian)(dian)卡，用(yong)于平常的(de)(de)购电(dian)(dian)(dian)、充值；

²  报警功效：电(dian)(dian)能(neng)表可(ke)设(she)置报警电(dian)(dian)量(liang)，电(dian)(dian)能(neng)表残剩电(dian)(dian)量(liang)小于(yu)显现报警电(dian)(dian)量(liang)时停止显现报警，在小于(yu)拉闸报警电(dian)(dian)量(liang)时给负载断电(dian)(dian)，提醒用(yong)户(hu)充(chong)值，此时可(ke)插购(gou)电(dian)(dian)卡规复供电(dian)(dian)，当用(yong)电(dian)(dian)量(liang)残剩电(dian)(dian)量(liang)为0时，电(dian)(dian)能(neng)表主动拉闸断电(dian)(dian)，用(yong)户(💃hu)购(gou)电(dian)(dian)充(chong)值后规复供电(dian)(dian)；

²  一(yi)(yi)卡(ka)多表功(gong)效：一(yi)(yi)户(hu)一(yi)(yi)卡(ka)，一(yi)(yi)卡(ka)最多可办理8只预(yu)支⛎费电表或(huo)水表；

²  补(bu)(bu)卡(ka)功(gong)效：电(dian)能表(biao)可与PC机售电(dian)体系共同完成补(bu)(bu)卡(ka)购(gou)量(liang)，补(bu)(bu)卡(ka)补(bu)(bu)量(li♛ang)，从头(tou)开户等多项操纵(zong)；

²  负(fu)(fu)(fu)荷(he)(he)检测：经(jing)由过(guo)程用(yong)(yong)户卡(ka)设置(zhi)电表(biao)(biao)参数(shu)，电能(neng)表(biao)(biao)可对用(yong)(yong)户现(xian)实(shi)负(f🌜u)(fu)(fu)载情况(kuang)停止检测，并在负(fu)(fu)(fu)荷(he)(he)过(guo)大(da)时断(duan)电实(shi)施(shi)自我掩(yan)护。用(yong)(yong)户在开(kai)户时可挑选设置(zhi)过(guo)载负(fu)(fu)(fu)荷(he)(he)参数(shu)，电能(neng)表(biao)(biao)在大(da)于(yu)过(guo)载负(fu)(fu)(fu)荷(he)(he)参数(shu)时主动断(duan)电，并显现(xian)“SUP_ _”提醒(xi♍ng)用(yong)(yong)户负(fu)(fu)(fu)荷(he)(he)过(guo)大(da)，用(yong)(yong)户可期待(dai)5～6分(fen)钟或(huo)拔出IC卡(ka)片(pian)给负(fu)(fu)(fu)载通电；
