²  报(bao)(bao)(bao)警(jing)(jing)功效：电(dian)(dian)能(neng)表(biao)可(ke)设置报(bao)(bao)(bao)警(jing)(jing)电(dian♛)(dian)量(liang)，电(dian)(dian)能(neng)表(biao)残(can)剩电(dian)(dian)量(liang)小(xiao)于(yu)显(xian)现报(bao)(bao)(bao)警(jing)(jing)电(dian)(dian)量(liang)时(shi)停止显(xian)现报(bao)(bao)(bao)警(jing)(jing)，𓆉在小(xiao)于(yu)拉(la)(la)闸(zha)报(bao)(bao)(bao)警(jing)(jing)电(dian)(dian)量(liang)时(shi)给负载断电(dian)(dian)，提醒用户(hu)充(chong)值，此时(shi)可(ke)插购(gou)电(dian)(dian)卡规复供(gong)电(dian)(dian)，当用电(dian)(dian)量(liang)残(can)剩电(dian)(dian)量(liang)为0时(shi)，电(dian)(dian)能(neng)表(biao)主动(dong)拉(la)(la)闸(zha)断电(dian)(dian)，用户(hu)购(gou)电(dian)(dian)充(chong)值后规复供(gong)电(dian)(dian)；

²  一(yi)卡多表功效(xiao)：一(yi)户一(yi)卡，一(yi)卡最多可办理꧒(li)8只预支(zhi)费电表或水表；

²  补卡功效(xiao)：电能表可(ke)与(🌞yu)PC机售电体系(xi)共同完成补卡购量，补卡补量ꦇ，从头开(kai)户(hu)等多(duo)项(xiang)操(cao)纵；

²  负(fu♔)(fu)(fu)荷(he)检测：经(jing)由过(guo)程用(yong)户(hu)(hu)卡设置电表参(can)♓(can)数，电能(neng)表可(ke)对用(yong)户(hu)(hu)现实(shi)负(fu)(fu)(fu)载(zai)情(qing)况停止检测，并在负(fu)(fu)(fu)荷(he)过(guo)大时(shi)断电实(shi)施自我掩护。用(yong)户(hu)(hu)在开户(hu)(hu)时(shi)可(ke)挑选设置过(guo)载(zai)负(fu)(fu)(fu)荷(he)参(can)(can)数，电能(neng)表在大于过(guo)载(zai)负(fu)(fu)(fu)荷(he)参(can)(can)数时(shi)主(zhu)动断电，并显现“SUP_ _”提醒用(yong)户(hu)(hu)负(fu)(fu)(fu)荷(he)过(guo)大，用(yong)户(hu)(hu)可(ke)期(qi)待5～6分钟或(huo)拔出IC卡片(pian)给(ji)负(fu)(fu)(fu)载(zai)通电；
