The min. and max. registrations include the following flow and power values with indication of date:
402 registers minimum and maximum flow and power on both monthly and yearly basis. The
registration can be read in full via data communication. Furthermore, a few monthly and yearly registers,
depending on the selected DDD-code, can be read from the display.

All max. and min. values are calculated as biggest and smallest average of a number of current flow or power
measurements respectively. The average period used for all calculations can be selected in the interval 1...1440
min. in one minute leaps. (1,440 min. = 24 hours).
Average period and target date must be stated in the order or reconfigured by means of METERTOOL. Unless
otherwise stated in the order, the default values - 60 min. for average period and target date applying to selected
delivery code - are used.
At the end of a year and a month the max. and min. values are saved in the data logger, and the current max. and
min. registers are “reset” according to the selected target date and the meter’s internal clock and calendar.
”Reset” sets the max. value to zero and the min. value to e.g. 10000.0 kW at CCC=419.
