6.2.3.1 Calculation of consumption / power from meter values
Settings on the controller
For the calculation of consumption and power using meter values of energy and quantity meters, the meter
constant and transformer constant in the controller must be set in Menu 4-1-6.
A: Meter constantThemeterconstantisusedfordeterminingtheenergyquantity(consumption).Thenumber
of pulses per kWh is determined. The meter constant only needs to be set for pulse meters; M-bus meters do
not have the meter constant!
Unit: pulses/kWh
B: Transformer constantCorrespondstotheconversionratioofthecurrenttransformer,i.e.therelationshipof
the current through the consumer (K/L) to the measuring current (k/l). The setting of the transformer constant
for pulse meters can be adjusted in the controller. Settings for M-bus meters cannot be made in the controller
as the necessary adjustments must strictly be made in the meter.
