日時段表號：編(bian)程時用(yong)來表(biao)示電表(biao)運行在第(di)幾日(ri)時段(duan)(duan)表(biao)，用(yong)1、2、3、4、5、6、7、8表(biao)示。如時區的日(ri)時段(duan)(duan)表(biao)號被設為0，則電表(biao)固定為第(di)1日(ri)時段(duan)(duan)表(biao)。

費率數：電(dian)能(neng)表能(neng)切換的費率號數。其值(zhi)不超過4。若設為(wei)3，則只有(you)費率1、費率2、費率3有(you)效，依此類(lei)推。如為(wei)0，則電(dian)表不論(lun)在哪(na)個日時段，只運行(xing)費率1。
