999.999)
M7. [phase]
VAh Total (display wraps around at 999.999)
M8

M11. [phase]
Power factor
M13
Mains edge count for the last accumulation interval
M13.1
Main edge count (accumulated) – zero transitions of the input
signal
M13.2
CE main edge count for the last accumulation interval
M14.1
Absolute
count for W pulses. Reset with CPC command.
M14.2
Count for W pulses in time window defined by the CPD command.
M15.1
Absolute
count for VAR pulses. Reset with CPC command.
M15.2
Count for W pulses in time window defined by the CPD command.
Example:
M3.3
Displays Wh total consumption of phase C.
M5.0
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
