Usually the average is determined over a period of 10, 15, 30 or 60 minutes. The beginning and the end of a measuring period are sent to the EML1101 by the energy supplier via pulse output on the counter. If a measuring period of 15 minutes is defined, the energy supplier subdivides every day into 24 x 4 = 96 measuring periods. -
