²  计量功效：撑(cheng)持正向(xiang)(xiang)、反向(xiang)(xiang)有功电能计量，此中反向(xiang)(xiang)电量计入正向(xiang)(ཧxiang)电量；

²  预支费办(ban)理功效(xiao)：电(dian)(dian)(dian)(dian)能(neng)表可与PC机(ji)售电(dian)(dian)(dian)(dian)体系共同完成预支费办(ban)理功效(xiao)。用户(hu)(hu)(hu)拔出开户(hu)(hu)(hu)卡，对电(dian)(dian)(dian)(dian)能(neng)表的报警电(dian)(dian)(dian)(dian)量、透支电(dian)(dian)(dian)(dian)量、限购电(dian)(dian)(dian)(dian)量、囤积电(dian)(dian)(dian)(dian)量、过载(zai)(zai)负(fu)荷等参(can)数停止设置，并向电(dian)(dian)(dian)(dian)能𒁃(neng)表充值(zhi)给(ji)负(fu)载(zai)(zai)通(tong)电(dian♚)(dian)(dian)(dian)；完成参(can)数设置后开户(hu)(hu)(hu)卡即成为用户(hu)(hu)(hu)的购电(dian)(dian)(dian)(dian)卡，用于平常的购电(dian)(dian)(dian)(dian)、充值(zhi)；

²  报(bao)(bao)(bao)(bao)警功(gong)效(xiao)：电(dian)(dian)(dian)(dian)(dian)能表可(ke)设置报(bao)(bao)(bao)(bao)警电(dian)(dian)(dian)(dian)(dian)量(liang)，电(dian)(dian)(dian)(dian)(dian)能表残剩电(d꧟ian)(dian)(dian)(dian)(dian)量(liang)小于显(xian)现(xian)报(bao)(bao)(bao)(bao)警电(dian)(dian)(dian)(dian)(dian)量(liang)时停(ting)止显(xian)现(xian)报(bao)(bao)(bao)(bao)警，在小于拉闸(zha)报(bao)(bao)(bao)(bao)警电(dian)(dian)(dian)(dian)(dian)量(liang)时给负载断电(dian)(dian)(dian)(dian)(dian)，提示用户充(chong)值(zhi)，此时可(ke)插购电(dian)(dian)(dian)(dian)(dian)卡规复供(gong)电(dian)(dian)(dian)(dian)(dian)，当用电(dian)(dian)(dian)(dian)(dian)量(liang)残剩电(dian)(dian)(dian)(dian)(dian)量(liang)为0时，电(dian)(dian)(dian)(dian)(dian)能表主动(dong)拉闸(zha)断电(dian)(dian)(dian)(dian)(dian)，用户购电(dian)(dian)(dian)(dian)(dian)充(chong)值(zhi)后规复供(gong)电(dian)(dian)(dian)(dian)(dian)；

²  一(yi)(yi)卡(ka)多表功(gong)效：一(yi)(yi)户一(yi)(yi)卡(ka)，一(yi)(yi)卡(kཧa)最多可办理8只预支费(fei)电(dian)表或水表；

²  补(bu)卡(ka)功效：电能表可与PC机🦹售电体系共同(tong)完(wan)成补(bu)卡(ka)购量，补(bu)卡(ka)补(bu)量，从头开户等多(duo)项操纵(zong)；

²  负(fu)(fu)(fu)荷(he)(he)检测：经由(you)过程用(yong)户(hu)(hu)卡设(she)置电表(biao)参数(shu)，电能表(biao)可🌌对用(yong)户(hu)(hu)现实(shi)负(fu)(fu)(fu)载(zai)情况停止检测，并在负(fu)(fu)(fu)荷(he)(he)过大(da)(da)时(shi)断(duan)电实(shi)施自我掩(yan)护。用(yong)户(hu)(hu)在开户(hu)(hu)时(shi)可选(xuan)择(ze)设(she)置过载(zai)负(fu)(fu)(fu)荷(he)(he)参数(shu)，电能表(biao)在大(da)(da)于(yu)过载(zai)负(fu)(fu)(fu)荷(he)(he)参数(shu)时(shi)主动断(duan)电，并显现“SUP_ _”提示用(yong)户(hu)(hu)负(fu)(fu)(fu)荷(he)(he)过大(da)(♛da)，用(yong)户(hu)(hu)可期待5～6分钟或拔(ba)出IC卡片(pian)给负(fu)(fu)(fu)载(zai)通电；
