Default = 0x00 0000
V1
RMS
contains the root mean square (RMS) value of V1, 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.
6.6.42 Instantaneous Current 2 (I2) – Page 16, Address 8
Default = 0x00 0000
I2 contains instantaneous current measurements for current channel 2.
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.
