Power factor sign convention
You can set the power factor sign (PF sign) convention that is used on the display to either IEC or IEEE.
PF sign convention: IEC
PF sign correlates with the direction of real power (kW) flow.
Quadrant 1 and 4: Positive real power (+kW), the PF sign is positive (+).
Quadrant 2 and 3: Negative real power (-kW), the PF sign is negative (-).
PF sign convention: IEEE
PF sign is correlates with the PF lead/lag convention, in other words, the effective load type (inductive or capacitive):
For a capacitive load (PF leading, quadrant 2 and 4), the PF sign is positive (+).
For an inductive load (PF lagging, quadrant 1 and 3), the PF sign is negative (-).
