Scaling
The scaling of the metered measurands, which are derived from
measured values, refers to:
60000 impulses per hour for V = V
prim
and I = I

(parameter address = 1102)
Example
In the parameter set is configured:
I
prim
= 100 A und V
prim
= 12 kV,
60000 impulses correspond so that:
1 h * 100 A * 12 kV *

= 2078.46 kWh
Note
The type of the update (cyclic, with or without deletion) and the update
interval must be programmed for the metered measurands (except for
the operating hours meter) with the parameterization software DIGSI.
