M0
Disables display updates
M1
Temperature (C° delta from nominal)
M2
Frequency
(Hz)

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.
Demo Code
revision 3.05 only.
M14.2 Count for W pulses in time window defined by the CPD command.
Demo
Code revision 3.05 only.
M15.1 Absolute count for VAR pulses. Reset with CPC command.
Demo Code
revision 3.05 only.
M15.2 Count for W pulses in time window defined by the CPD command.
Demo
Code revision 3.05 only.
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 for all
phases
