For block interval demand calculations, you select a block of time (interval) that the power meter uses for the demand calculation and the mode the meter uses to handle the interval. 2 different modes are possible:Fixed block - Select an interval from 10, 15, 20, 30, 60 minutes. The power meter calculates and updates the demand at the end of each interval.Sliding block - Select an interval from 10, 15, 20, 30, 60 minutes. For demand intervals less than 15 minutes, the value is updated every 15 seconds. For demand intervals of 15 minutes and greater, the demand value is updated every 60 seconds. The power meter displays the demand value for the last completed interval.The following figures illustrate the 2 ways to calculate demand power using the block method. For illustration purposes, the interval is set to 15 minutes.DOCA0005EN-12iEM3000 series user manualFront panel display and meter setupPeak Demand
