It shows whether important information has been reset or manipulated, for instance if meter has

Data logger / Consumption alarm
The integrated data logger has 26 logging periods in which data can be stored daily, weekly or
monthly. The logger stores the consumption for totalizer 1 and totalizer 2 in the selected period.
Forward consumption is stored as a positive value and reverse consumption is stored as a
negative value. Alarm and meter status are also stored for the same period to indicate alarms
that have been active, or that revenue data has been influenced in the specific period.
The logged information has a time and date stamp. The data logger never stops storing data -
old data is overwritten following the first in/first out principle, i.e. log 1 is the last stored
information which is moved to log 2 when the next logging is made and so on.
The consumption alarm indicates that the actual consumption on totalizer 1 is above or below
the consumption limits.
