²  计(ji)量功效：电(dian)能(neng)表可计(ji)量三相正(zhen🌊g)、反向有功电(dian)能(neng)，反✨向电(dian)能(neng)按正(zheng)向累(lei)计(ji)；

²  预支费(fei)办理(li)功效(xiao)：电(dian)能(neng)表可(ke)与(yu)PC机售(shou)电(dian)体系共同完成预支费(fei)办理(li)功效(xiao)。用(yong)户拔出(chu)开(kaꦆi)户卡，对电(dian)能(neng)表的报警电(dian)量(liang)、透支电(dian)量(liang)、限购电(dian)量(liang)、囤(dun)积电(dian)量(liang)、过载负荷(he)等(deng)参数停(ting)止设置，并(bing)向电(dian)能(neng)表充(chong)值给负载通电(dian)；完成参数设置后(hou)开(kai)户卡即成为用(yong)户的购电(dian)卡，用(yong)于平常的购电(dian)、充(chong)值；

²  报(bao)警功效：电(dian)(dian)(dian)能表可设置报(bao)警电(dian)(dian)(dian)量(liang)，电(dian)(dian)(dian)能表残(can)剩电(dian)(dian)(dian)量(liang)小于(yu)显现报(bao)警电(dian)(dian)(dian)量(liang)时(shi)(shi)(shi)停止显现报(bao)警，在小于(yu)拉(la)(la)闸(zha)报(bao)警电(dian)(dian)(dian)量(liang)时(shi)(shi)(shi)给负载断电(dian)(dian)(dian)，提示用户充(chong)值，此时(shi)(shi)(shi)可💯插购电(dian)(dian)(dian)卡规(gui)复供(gong)电(dian)(dian)(dian)，当用电(dian)(dian)(dian)量(liang)残(can)剩电(dian)(dian)(dian)量(liang)为0时(shi)(shi)(shi)，电(dian)(dian)(dian)能表主动拉(la)(la)闸(zha)断电(dian)(dian)(dian)，用户购电(dian)(dian)(dian)充(chong)值后(hou)规(gui)复供(gong)电(dian)(dian)(dian)；

²  一(yi)(yi)(yi)卡多表功效：一(yi)(yi)(yi)户一(yi)(yi)(yi)卡，一(yi)(yi)(yi)卡最多可办☂(ban)理8只预支费电表🃏或水表；

²  补(bu)卡功(gong)效：电(dian)能表可(ke)与PC机售电(dian)体系共同完成补(bꦜu)卡购量(liang)，补(bu)卡补(bu)量(liang)，从头(tou)开户等多项操(cao)纵；

²  负荷(he)检测：经由过(guo)程用(yong)(yong)户卡(ka)设(she)置电(dian)表(biao)参数，电(dian)能表(biao)可对用(yong)(yong)户现实(shi)负载情况(kuang)停止检测，并在负荷(he)过(guo)大时断电(dian)实(shi)施自我掩护。用(yong)(yong)户在开户时可选择设(she)置过(guo)载负荷(he)参数，电(dian)能表(bඣiao)在大于(yu)过(guo)载负荷(he)参数时主动(dong)断电(dian)，并显现“SUP_ _”提(ti)示用(yong)(yong)户负荷(he)过(guo)大，用(yong)(yong)🎀户可期待5～6分钟或拔出(chu)IC卡(ka)片给负载通电(dian)；
