(45 to 66 Hz, power factor = 0.5)
Polarity display
For (consumption) No symbol
For (regeneration) "-"
Reactive Power Measurement
Measurement range
Depends on the voltage x current range combination.
Reactive-power-meter
method
Not used: Calculate using the voltage, current, and active-power
measurements.
Used: Measure the reactive power directly using the reactive-power-
meter method.
