Page 164 Number of demand sub-intervals Demand Sync Method Accura 2300S supports two methods for synchronizing the starting time of a demand sub-interval: hourly auto sync and manual sync. Hourly auto sync allows the demand sub-interval to automatically start every hour. Manual sync allows users to manually start the demand sub-interval at the time users issue a sync command.
Page 165 Calculation of Total Power Accura 2300S supports two methods for calculation of the total power based on power per phase. One is to calculate the total power based on the vector sum of 3-phase apparent power. And the other is to calculate the total power based on the arithmetic sum of magnitudes of 3-phase apparent power vectors.
