Max/Min Demand menu
Max/min demand functionality is used to measure and store in the product flash memory the maximum
and minimum demand values referred to a specific time period (day, week, month) of main real time
measured. Demand values are calculated over a specific time interval (from 1 to 60 minutes). When the
last interval of an ongoing period has finished, the maximum and/or minimum values are stored together
with the timestamps, and a new period starts. Therefore, within the defined time period M4M will
provide the max/min demand values calculated over the time interval. It is possible to store also the 2nd
and the 3rd max/min. Max/min demand functionality allows to store up to the 3 highest and/or lowest
demand values per each parameter. Up to 25 parameters, thus up to 25 channels of flash memory can be
configured.
