²  报(bao)(bao)警(jing)(jing)功效(xiao)：电(dian)(dian)(dian)能表可设置报(baꦿo)(bao)警(jing)(jing)电(dian)(dian)(dian)量(liang)，电(dian)(dian)(d🔴ian)能表残剩电(dian)(dian)(dian)量(liang)小(xiao)(xiao)于显现报(bao)(bao)警(jing)(jing)电(dian)(dian)(dian)量(liang)时停止显现报(bao)(bao)警(jing)(jing)，在小(xiao)(xiao)于拉闸报(bao)(bao)警(jing)(jing)电(dian)(dian)(dian)量(liang)时给(ji)负载断电(dian)(dian)(dian)，提醒用(yong)户充(chong)值，此时可插购(gou)电(dian)(dian)(dian)卡(ka)规(gui)复供(gong)电(dian)(dian)(dian)，当用(yong)电(dian)(dian)(dian)量(liang)残剩电(dian)(dian)(dian)量(liang)为0时，电(dian)(dian)(dian)能表主动(dong)拉闸断电(dian)(dian)(dian)，用(yong)户购(gou)电(dian)(dian)(dian)充(chong)值后规(gui)复供(gong)电(dian)(dian)(dian)；

²  一卡多表(biao)(biao)功效：一户一卡，一卡最多可办理(li)8只预支ಌ费电表(biao)(biao)𓃲或(huo)水(shui)表(biao)(biao)；

²  补卡功效(xiao)：电能(neng)表可与(yu)PC机售电体系共同完(wan)成﷽补卡购量，补卡补量，从(cong)头(tou)开(kai)户等多(duo)项(xiang)操(cao)纵；

²  负(fu)(fu)荷(he)检测：经由(you)过(guo)(guo)程用(yong)户(hu)(hu)卡设置(zhi)电(dian)表(biao)参数(shu)，电(dian)能(neng)表(biao)可(ke)(ke)对(dui)用(yong)户(hu)(hu)现实负(fu)(fu)载(zai)(zai)情况(kuang)停止检测，并(bing)在(zai)(zai)负(fu)(fu)荷(he)过(guo)(guo)大(da)时断电(dian)实施自我掩护(hu)。用(yong)户(hu)(hu)在(zai)(zai)开户(hu)(hu)时可(ke)(ke)挑选设置(zhi)过(guo)(guo)载(zai)(za💖i)负(fu)(fu)荷(he)参数(shu)，电(dian)能(neng)表(biao)在(zai)(zai)大(da)于过(guo)(guo)载(zai)(zai)负(fu)(fu)荷(he)参数(shu)时主动断电(dian)，并(bing)显现“SUP_ _”提(ti)醒(xing)用(yong)户(hu)(hu)负(fu)(fu)荷(he)过(guo)(guo)大(da)，用(yong)户(hu)(hu)可(ke)(ke)期待5～6分钟或拔出IC卡片(pian)给负(fu)(fu)载(zai)(zai)通(tong)电(dian)；
