6.6.33 Active Power (P
AVG
) – Page 16, Address 5
Default = 0x00 0000
Instantaneous power is averaged over each low-rate interval (SampleCount samples) and then added with
power offset (P
OFF
) to compute active power (P
AVG
).
This is a two's complement value in the range of -1.0  value  1.0, with the binary point to the right of the
MSB.
6.6.34 RMS Current (I
RMS
) – Page 16, Address 6
Default = 0x00 0000
I
RMS
contains the root mean square (RMS) values of I, calculated during each low-rate interval.
This is an unsigned value in the range of 0value1.0, with the binary point to the left of the MSB.
6.6.35 RMS Voltage (V
RMS
) – Page 16, Address 7
Default = 0x00 0000
V
RMS
contains the root mean square (RMS) value of V, calculated during each low-rate interval.
This is an unsigned value in the range of 0value1.0, with the binary point to the left of the MSB.
6.6.36 Reactive Power (Q
Avg
) – Page 16, Address 14
Default = 0x00 0000
Reactive power (Q
AVG
) is Q averaged over each low-rate interval (SampleCount samples) and corrected by
Q
OFF
.
This is a two's complement value in the range of -1.0  value  1.0, with the binary point to the right of the
MSB.
