    Operation 5.2. Usage Depending on the Application (Alarm, Periodic Active Energy, Rolling Demand, Operating Time, Password, etc.) 5.2.7. Rolling Demand Display and Calculation Rolling demand is calculated by dividing the active/reactive/apparent energy during a specified period (interval) *1 by the length of that period. For block interval demand, you specify a period of time interval (or block) that this instrument uses for the demand calculation.
