* Register 35: Setting in the register defines the scaling factor PI for energy values
C. User Scaling OFF, Measurement with Current Transformer 500:1 A
(1A Variants) and 500:5 A (5A Variants)
D-CTR values of 500 or 100 must be taken into account externally when user
scaling is OFF, i.e. the transferred measured value must be multiplied by 500 or
100 in the high-level PLC.
