Make sure to set the pulse unit of watt-hour meters.
Otherwise, the consumption can not be measured correctly thus hindering the
normal charging function.
The power consumption is taken as an accumulated integrating value, and the
performance and accuracy are depending on that of the watt-hour meter or CT.
Therefore, we are not liable in this regard.
