Absolute count for VARh pulses. Reset with CPC command.
I RMS display
V RMS display
Displays Wh total consumption of phase C.
Displays VARh total consumption for all phases.
Displays for total consumption wrap around at 999.999Wh (or VARh, VAh) due to the limited number of
available display digits. Internal registers (counters) of the Demo Code are 64 bits wide and do not wrap
around.
When entering the phase parameter, use 1 for phase A, 2 for phase B, 3 for phase C, and 0 or blank for all
phases .
