Display of rolling demand
The rolling demand is the value obtained by dividing the active energy (imported) in a specified time (interval) by the length
of the interval.
The block interval demand is to select the time width (interval) of the “block” used for the demand calculation.
(For setting of the rolling demand display, refer to page 32.)
This is displayed when the button is pressed repeatedly in the operation mode to switch the measurement
displays.
