6.6.44 Instantaneous Active Power 2 (P2) – Page 16, Address 10
Default = 0x00 0000
P2 contains instantaneous power measurements for current and voltage channels 2.
Values in registers I2 and V2 are multiplied to generate this value. 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.
6.6.45 Active Power 2 (P2
AVG
) – Page 16, Address 11
Default = 0x00 0000
Instantaneous power is averaged over each low-rate interval (SampleCount samples) to compute active pow-
er (P2
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.
6.6.46 RMS Current 2 (I2
RMS
) – Page 16, Address 12
Default = 0x00 0000
I2
RMS
contains the root mean square (RMS) value of I2, 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.
6.6.47 RMS Voltage 2 (V2
RMS
) – Page 16, Address 13
Default = 0x00 0000
V2
RMS
contains the root mean square (RMS) value of V2, 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.
