²  计量(liang)功效：撑持正(zheng)向、反(fan)向有功电(di꧙an)能(neng)计量(liang)，此中反(fan)向电(dian)量(liang)计入正(zheng)向电(dian)量(liang)；

²  预支费(fei)办理功效(xiao)：电(dian)能(neng)表可(ke)与PC机售电(dian)体系共同完成(cheng)(cheng)预支费(fei)办理功效(xiao)。用(yong)户(hu)拔出开(kai)户(hu)卡，对电(dian)能(neng)表的报警电(dian)量(liang)、透支电(dian)量(liang)、限购(gou)电(dian)量(liang)、囤积电(dian)量(liang)、过载(zai)负(fu)荷等参数停止(zhi)设置，并向电ꦯ(dian)能(neng)表充值给负(fu)载(zai)通电(dian)；完成(cheng)(cheng)参数设🍷置后开(kai)户(hu)卡即成(cheng)(cheng)为用(yong)户(hu)的购(gou)电(dian)卡，用(yong)于平常的购(gou)电(dian)、充值；

²  报警(jing)功效：电(dian)能(neng)表(biao)可(ke)设置报警(jing)电(dian)量，电(dian)能(neng)表(biao)残(can)剩(sheng)电(dian)量小(xiao)于显(xian)现(xian)(xian)报警(jing)电(di꧒an)量时(shi)(shi)停止显(xian)现(xian)(xian)报警(jing)，在小(xiao)于拉(la)闸(zha)(zha)报警(jing)电(dian)量时(shi)(shi)给负载(zai)断电(dian)，提(ti)醒用(yong)户充值(zhi)，此时(shi)(shi)可(ke)插购电(dian)卡(ka)规复(fu)(fu)供(gong)电(dian)，当用(yong)电(dian)量残(can)剩(sheng)电(dian)量为(wei)0时(shi)(shi)，电(dian)能(neng)表(biao)主动(dong)拉(la)闸(zha)(zha)断电(dian)，用(yong)户购电(dian)充值(zhi)后规复(fu)(fu)供(gong)电(dian)；

²  一卡多表功(gong)效：一户一卡，一卡最多可(ke)办理8只预支费电表或水表；

²  补(bu)(bu)(bu)卡功效：电能(neng)表可与PC机售电体系(xi)共同完成补(bu)(bu)(bu)卡购(gou)量，ꦦ补(bu)(bu)(bu)卡补(bu)(bu)(bu)量，从(cong)头(tou)开户等多(duo)项(xiang)操(cao)纵；

²  负(fu)(fu)荷(he)检测：经由过(guo)(guo)程用户(hu)卡设置电(dian)表(biao)参(can)数(shu)，电(dian)能(neng)表(biao)可(ke)(ke)对(dui)用户(hu)现实负(fu)(fu)载🐭情况(kuang)停(ting)止检测，并(bing)(bing)在(zai)负(fu)(fu)荷(he)过(guo)(guo)大时(shi)断电(dian)实施自我掩护。用户(hu)在(zai)开户(hu)时(shi)可(ke)(ke)挑选设置过(guo)(guo)载负(fu)(fu)荷(he)参(can)数(shu)，电(dian)能(neng)表(biao)在(zai)大于(yu)过(guo)(guo)载负(fu)(fu)荷(he)参(can)数(shu)时(shi)主动断电(dian)，并(bing)(bing)显现“SUP_ _”提(ti)醒用户(hu)负(fu)(fu)荷(he)过(guo)(guo)大，用户(hu)可(ke)(ke)期(qi)待5～6分钟(zhong)或(huo)拔(ba)出IC卡片给负(fu)(fu)载通电(dian)；
