i.e., energy is displayed up to 9.999 MWh (Mvarh, MVAh) with resolution 0.001 MWh.

The roll value may be changed in accordance with the average load of the power line.
For example, if average power is 400 kW and the counter must be reset every 3
months (2160 hours), then energy during this period equals 864000 kWh (6 digits) and
the roll value = 10.E6.
