²  计(ji)量꧙功效(xiao)：电能表可计(ji)量三相正、反向有功电能，反向电能按正向累计(ji)；

²  费控形式转换功效(xiao)：电能(neng)表备长途预支(zhi)费和本(ben)地预支(zhi๊)费功效(xiao)，两(liang)种(zhong)形式能(neng)够(gou)按照办理须要随时转换；

²  充(chong)值功效(xiao)：电(dian)(dian)表(biao)在本地预支(zhi)费(fei)形(xing)式时，用(yong)户(hu)必须先(xian)充(chong)值后用(yong)电(dian)(dian)，主动结算计费(fei)、扣费(fei)，无费(fei)断电(dian)(dian)，  用(yong)户(hu)充(chong)值冲正余额(e)后电(dian)(dian)表(biao)主动合闸供电(di🐭a𝄹n)(dian)；

²  退费功(gong)效：当用户搬迁时，如电表内仍(reng)不足额，能够将预缴金额退还用户，而(er🎐)后将电表余额主动“归零(ling)”；
