Energy pulsing considerations
The meter’s energy pulsing LED and pulse outputs
are capable of energy pulsing within specific limits.

The pulse rate depends on the voltage, current and PF of the input signal source, the number of phases, and the VT and CT ratios.
If Ptot is the instantaneous power (in kW) and K is the pulse constant
(in pulses per kWh), then the pulse period is:
