Measurement results / sub-results
P
Active power
S
Apparent power
Q
Reactive power (capacitive or inductive)
PF
Power factor (capacitive or inductive)
Φ
Phase displacement between voltage and current in degrees
NOTE:
Voltage test terminals connection and current flow toward load should be considered; the red voltage terminal
should be connected to the Line terminal and the jaw should be correctly oriented to obtain positive sign of
Power test result. If Power test result has negative sign, connection of the voltage terminal or jaw orientation
are reversed. The result of phase displacement angle has opposite sign as well. Consequently, load
character determination (capacitive or inductive) is switched.
