Reactive power: Q = Ai × (PT1 / PT2) × (CT1 / CT2), Ai signed
integers, unit:var.
Apparent power: S = Ai × (PT1 / PT2) × (CT1 / CT2), Ai is an
unsigned integer, unit:VA.
Power factor: PF = Ai / 1000, Ai signed integers, no unit.
Frequency: F = Ai / 100, Ai as an unsigned integer, unit:Hz.
Active energy: Ep = Ai / 10, Ai unsigned long integer (0 ~
999,999,999), unit:kWh.
Reactive energy: Eq = Ai / 10, Ai unsigned long integer (0 ~
999,999,999), unit:kvarh.
