• End of integration
If the threshold value is exceeded during the integration period, the meter indicates an excess at the end of
the integration period and during subsequent integration periods. At the end of each integration period the
excess demand indicators are reset only if the rising value has remained lower than the excess threshold.
• Projection
Every second, the meter calculates and extrapolates the demand to the end of the current integration period.
If the demand threshold value is exceeded by the extrapolated value, the meter immediately indicates an
excess. This calculation is always inhibited during the first 30% of the integration period.
The illustration below shows the different excess demand indication characteristics for each of the modes:
[A] Rising demand mode 1 Rising value
[B] End of integration mode 2 Excess demand threshold
[C] Projection mode 3 Integration periods
4 Elapsed time
5 Excess demand indication
6 30% of integration period
