4.3.14.10.14 ADC measurement configuration checksum 0
4.3.14.10.14.1 High word for power line constants
Name:
PLconstH
Data type Value
UINT 0 to 65,535
Basis value of power line constant = 0x4A817C80 = 1,250,000,000 corresponding to 360 CF pulses per kWh
or 0.1 CF pulse per kWs. The result of setting the resolution in the energy registers to a decimal (see register
"MeteringMode" <Bit 9>) is 1 kWs per digit. Power line constant / 10 results in a 10x resolution.
4.3.14.10.14.2 Low word for power line constants
Name:
PLconstL
Data type Value
UINT 0 to 65,535
Basis value of power line constant = 0x4A817C80 = 1,250,000,000 corresponding to 360 CF pulses per kWh
or 0.1 CF pulse per kWs. The result of setting the resolution in the energy registers to a decimal (see register
"MeteringMode" <Bit 9>) is 1 kWs per digit. Power line constant / 10 results in a 10x resolution.

Comments regarding measurement configurations:
Measuring configuration Note
3P4W Monitors the phasing of voltages and currents: Phase A before phase B before phase C
Measuring configuration: Phase A and phase C, N connection bridges to phase B or open
Measurement: e.g. the 2 phases A and C and the 2 corresponding currents are measured, phase B disabled
3P3W
Monitors the phasing of voltages and currents: Phase difference between A and C >180°
