²  计量功(gong)效(xiao)：电能(neng)(neng)表可(ke)计量ꦗ三相正(zheng)、反向(xiang)有功(gong)电能(neng)(neng)，反向(xiang)电能(neng)(neng)按正(zheng)向(xiang)累(lei)计；

²  预(yu)支(zhi)费办理功(gong)效(xiao)(xiao)：电能表(biao)可与(yu)PC机售电体系共同完成预(yu)支(zhi)费办理功(gong)效(xiao)(xiao)。用户(hu)(hu)拔出开(kai)(kai)户(hu)(hu)卡(ka)，对电能表(biao)的报(bao)警电量(liang)(liang)、透支(zhi)电量(liang)(liang)、限(xian)购电量(liang)ဣ(liang)、囤(dun)积电量(liang)(liang)、过载负荷等参数停止(zhi)设置(zhi)，并向电能表(biao)充值(zhi)给(ji)负载通电；完成参数设置(zhi)后开(kai)(kai)户(hu)(hu)卡(ka)即(ji)成为用户(hu)(hu)的购电卡(ka)，用于平常的购电、充值(zhi)；

²  报(bao)警功效：电(dian)能表可(ke)设置报(bao)警电(dian)量(liang)，电(dian)能表残(can)剩电(dian)量(liang)小于(yu)显(xian)现报(bao)警电(dian)量(liang)时停止显(xian)现报(bao)警，在小于(yu)拉闸(zha)报(bao)警电(dian)量(liang)时给负载断电(dian)，提醒用户充值(zhi)，此时可(ke)插(cha)购(gou)电(dian)卡规(gui)复供(gong)电(dian)，当用电(dian)量(liang)残(can)剩电(dian)量(liang)为0时，电(dian)能表主动拉闸(zha)断电(dian)，用户购(gou)电(dian)充值(zh෴i)后规(gui)复供(gong)电(dian)；

²  一(yi)(yi)卡多表(biao)功效：一(yi)(yi)户一(yi)(yi)卡，一(yi)💞(yi)卡最多可办(ban)理8只(zhi)预支(zhi)费电表(biao)或水表(biao)；

²  补卡(ka)功效(xiao)：电(dian)能表可与PC机售电(dian)体系共同完(wan)成补卡(ka)购量(liang)，补卡(ka)补💝量(liang)，从头开户等多项操纵；

²  负(fu)(fu)荷检测：经由过(guo)程用(yong)(yong)户(hu)卡(ka)设(she)置电(dian)表参数(sh♏u)(shu)，电(dian)能(neng)表可对用(yong)(yong)户(hu)现(xian)实负(fu)(fu)载꧂情况停(ting)止检测，并(bing)在(zai)负(fu)(fu)荷过(guo)大(da)时(shi)断电(dian)实施(shi)自我掩护。用(yong)(yong)户(hu)在(zai)开户(hu)时(shi)可挑选设(she)置过(guo)载负(fu)(fu)荷参数(shu)(shu)，电(dian)能(neng)表在(zai)大(da)于过(guo)载负(fu)(fu)荷参数(shu)(shu)时(shi)主动断电(dian)，并(bing)显(xian)现(xian)“SUP_ _”提醒用(yong)(yong)户(hu)负(fu)(fu)荷过(guo)大(da)，用(yong)(yong)户(hu)可期待5～6分钟或拔出IC卡(ka)片给(ji)负(fu)(fu)载通(tong)电(dian)；
