7.2.3.1 SIOX - connection of energy, gas, water and event meters
Configuration of meter and transformer constant (Menu 4-1-6):
Meter constant (pulses per kWh or m
3
)
Transformer constant (conversion ratio of current transformer)
Unit (unit of measure kWh or m
3
)
For further details, see chapter Calculation of consumption / power from meter values.

The following minimum times must be observed when recording meter pulses (pulse interface).
Conditions
For counting pulses, these must be at least 95 ms apart from each other.
Faster pulse sequences will not be detected; the pulse width must be at least 30 ms.
When using electronic meters, the settings with regard to their meter and transformer constants must
be taken into account, otherwise the controller produces incorrect energy evaluation due to incorrect
meter and transformer relationships!
