²  报(bao)警功效：电(dian)(dian)能表(biao)(biao)(biao)可设置(zhi)报(bao)警电(dian)(dian)量(liang)(liang)，电(dian)(dian)能表(biao)(biao)(biao)残(can)剩(sheng)电(dian)(dian)量(liang)(liang)小于显(xian)现报(bao)警电(dian)(dian)量(liang)𝔍(liang)时停止显(xian)现报(bao)警，在小于拉闸报(bao)警电(dia꧅n)(dian)量(liang)(liang)时给负(fu)载断(duan)电(dian)(dian)，提醒用(yong)户充(chong)值，此时可插购电(dian)(dian)卡(ka)规复供电(dian)(dian)，当用(yong)电(dian)(dian)量(liang)(liang)残(can)剩(sheng)电(dian)(dian)量(liang)(liang)为0时，电(dian)(dian)能表(biao)(biao)(biao)主动拉闸断(duan)电(dian)(dian)，用(yong)户购电(dian)(dian)充(chong)值后规复供电(dian)(dian)；

²  一(yi)卡多表(biao)功效：一(yi)户一(yi)卡，一(yi)卡最(zui)多可办理8只(zhi)预支费电表ꦐ(biao)或水表(biao)；

²  补卡(ka)(ka)功效(xiao)：电(dian)能表可与(yu)PC机(ji)售电(dian)体(ti)系共同完成(cheng)补卡(ka)(ka)购量，补卡(ka)(👍ka)补量，从头开(kai)户(hu)等多项操纵；

²  负(fu)(fu)荷(he)(he)检测(ce)：𝓰经由过(guo)(guo)程用户卡设(she)置(zhi)电(dian)表(biao)参数(shu)，电(dian)能表(biao)可对用户现实(🌄shi)负(fu)(fu)载情(qing)况停(ting)止检测(ce)，并(bing)在负(fu)(fu)荷(he)(he)过(guo)(guo)大(da)时(shi)断(duan)电(dian)实(shi)施自我掩护。用户在开户时(shi)可挑选设(she)置(zhi)过(guo)(guo)载负(fu)(fu)荷(he)(he)参数(shu)，电(dian)能表(biao)在大(da)于(yu)过(guo)(guo)载负(fu)(fu)荷(he)(he)参数(shu)时(shi)主动断(duan)电(dian)，并(bing)显现“SUP_ _”提醒用户负(fu)(fu)荷(he)(he)过(guo)(guo)大(da)，用户可期待5～6分(fen)钟或拔出IC卡片给负(fu)(fu)载通(tong)电(dian)；
