²  计量功(gon🎶g)效：电能(neng)表可计量三相(xiang)正、反向有功(gong)电能(neng)，反向电能(neng)按(an)🎶正向累计；

²  预支(zhi)费办(ban)理(li)功效：电(dian)能(neng)表可与PC机售电(dian)体系𓆏共(gong)同完(wan)成(cheng)预支(zhi)费办(ban)理(li)功效。用(yong)户(hu)(hu)拔(ba)出开户(hu)(hu)卡(ka)，对(dui)电(dian)能(neng)表的(de)(de)报(bao)警电(dian)量(liang)、透支(zhi)电(dian)量(liang)、限购电(dian)量(liang)、囤(du🗹n)积电(dian)量(liang)、过载(zai)负荷(he)等(deng)参(can)数停(ting)止设(she)置，并(bing)向电(dian)能(neng)表充值给负载(zai)通电(dian)；完(wan)成(cheng)参(can)数设(she)置后开户(hu)(hu)卡(ka)即成(cheng)为用(yong)户(hu)(hu)的(de)(de)购电(dian)卡(ka)，用(yong)于平常的(de)(de)购电(dian)、充值；

²  报警(jing)功效：电(dian)(dian)(dian)(dian)能表可设置(zhi)报警(jing)电(dian)(dian)(dian)(dian)量(liang)(liang)，电(dian)(dian)(dian)(dian)能表残剩电(dian)(dian)(dian)(dian)量(liang)(liang)小于(yu)显(xian)现(xian)报警(jing)电(dian)(dian)(dian)(dian)量(liang)(liang)时(shi)(shi)(shi)停止显(xian)现(xian)报警(jing)，在小于(yu)拉(la)闸报警(jing)电(dian)(dian)(dian)(dian)量(liang)(liang)时(shi)(shi)(shi)给负载断(duan)电(dian)(dian)(dian)(ꦓdian)，提示用户充值，此时(shi)(shi)(shi)可插购电(dian)(dian)(dian)(dian)卡(ka)规复供电(dian)(dian)(dian)(dian)，当用电(dian)(dian)(dian)(dian)量(liang)(liang)残剩电(dian)(dian)(dian)(dian)量(liang)(liang)为0时(shi)(shi)(shi)，电(dian)(dian)(dian)(dian)能表主动(dong)拉(la)闸断(duan)电(dian)(dian)(dian)(dian)，用户购电(dian)(dian)(dian)(dian)充值后(hou)规复供电(dian)(dian)(dian)(dian)；

²  一(yi)卡(ka♍🍸)多表功效(xiao)：一(yi)户一(yi)卡(ka)，一(yi)卡(ka)最多可办理8只预支费电表或水表；

²  补卡功效：电能表可与PC机售🉐电体系(xi)共(gong)同完成补卡购量(liang)，补卡补量(liaౠng)，从(cong)头开户等多(duo)项操纵；

²  负(fu)荷(he)检测(ce)：经由(you)过程用户卡(ka)(ka)设(she)置电表参数(shu)(shu)(shu)，电能表可对用户现(xian)实负(fu)载情(qing)况停止检测(ce)，并在负(fu)荷(he)过大(da)时断(duan)电实施自我掩(yan)护。用户在开户时可选(xuan)择设(she)置过载负(fu)荷(he)参数(shu)(shu)(shu)，电能表在大(da)于过载负(fu)荷(he)参数(shu)(shu)(shu)时主动断(duan)电，并显现(xian)“SUP_ _”提示用户负(fu)荷(ℱhe)过大(da)，用户可期待(dai)5～6分钟或拔出IC卡(ka)(ka)片给负(fu)载通电🌄；
