The values of two measurement quantities (incl. pulse inputs EX1 and EX2)
can be added.
Energy registers which contain the summation of two measured quantities
(summation channels) cannot be used for tariffication.

A non-volatile memory (FLASH memory) contains the data of:
the stored value profile
the load profile 1
the load profile 2 (optional)
the event log
the three groups of dedicated event logs
The flash memory stores data without data loss in case of voltage failures.
No battery is required for this purpose.
The total size of the available memory for the stored billing value profile, the
load profile(s), the event log and the dedicated event logs is 1.8 MB.
At the end of the billing period, the meter stores the current value of the
registers to the stored value profile. Which energy registers and/or demand
registers are stored to the stored billing value profile can be selected by
parameterisation.
The stored value profile is organised as a circular buffer, i.e. the oldest
entry will be overwritten by the most recent entry. The memory capacity
which is available for the stored value profile depends on parameterisation.
The load profiles are used to save the values of various registers at regular
intervals. The measured values that are captured in the load profile can be
selected by parameterisation.
Load profile 2 is optional
The second load profile is optional.
