²  报(bao)警(jing)功(gong)效：电(dian)(dian)(dian)能(neng)(neng)表可设置报(bao)警(jing)电(dian)(dian)(dian)量(lia𒁃ng)(liang)(liang)，电(dian)(dian)(dian)能(neng)(neng)表残剩电(dian)(dian)(dian)量(liang)(liang)(liang)小于显(xian)现报(bao)警(jing)电(dian)(dian)(dian)量(liang)(liang)(liang)时(shi)停止(zhi)显(xian)现报(bao)警(jing)，在小于拉(la)闸(zha)报(bao)警(jing)电(dian)(dian)(dian)量(liang)(liang)(liang)时(shi)给负载(zai)断(duan)电(dian)(dian)(dian)，提醒(xing)用(yong)户(hu)充值，此(ci)时(shi)可插(cha)购电(dian)(dian)(dian)卡规复供电(dian)(dian)(dian)，当用(yong)电(dian)(dian)(dian)量(liang)(liang)(liang)残剩电(dian)(dian)(dian)量(liang)(liang)(liang)为0时(shi)，电(dian)(dian)(dian)能(neng)(neng)表主动拉(la)闸(zha)断(duan)电(dian)(dian)(dian)，用(yong)户(hu)购电(dian)(dian)(dian)充值后规复供电(dian)(dian)(dian)；

²  一(yi)(yi)卡(ka)多(duo)表(biao)功效(xiao)：一(yi)(yi)户ဣ一(yi)(yi)卡(ka)，一(yi)(yi)卡𝓰(ka)最(zui)多(duo)可办理(li)8只预支(zhi)费电表(biao)或(huo)水表(biao)；

²  补(bu)(bu)(bu)卡(ka)功效：电能表可(ke)与PC机售电体系(xi)共同完成补(bu)(bu꧋)(bu)卡(ka)购量，补(bu)(bu)(bu)卡(ka)补(bu)(bu)(bu)量，从头(tou)开户等(deng)多项操纵(zong)；

²  负(fu)(fu)荷(he)(he)检测(ce)：经由过(guo)(guo)程用户(hu)卡设(she)置(zhi)电🐻(dian)表参数，电(dian)能表可(ke)对用户(hu)现实(shi)负(fu)(fu)载(🍸zai)情(qing)况(kuang)停(ting)止检测(ce)，并在负(fu)(fu)荷(he)(he)过(guo)(guo)大时断电(dian)实(shi)施自(zi)我掩护。用户(hu)在开户(hu)时可(ke)挑选(xuan)设(she)置(zhi)过(guo)(guo)载(zai)负(fu)(fu)荷(he)(he)参数，电(dian)能表在大于过(guo)(guo)载(zai)负(fu)(fu)荷(he)(he)参数时主动断电(dian)，并显现“SUP_ _”提(ti)醒用户(hu)负(fu)(fu)荷(he)(he)过(guo)(guo)大，用户(hu)可(ke)期待(dai)5～6分钟或拔出(chu)IC卡片给负(fu)(fu)载(zai)通电(dian)；
