4.2.18 Calculation of the power factor
Measurement range (1)
-1.00 to +1.00
Specified measurement range
0 to 50% of the
measurement range
50 to 100% of the
measurement range
Uncertainties (7)
± (3% R +3 pt)
± (2% R +3 pt)
Resolution
0.01
Note (1) - If one of the terms in the calculation of the power factor is displayed as
"OL", or forced to zero, the display of the power factor is an indeterminate
value "----".
Note (7) of the previous § apply.
Note 9 - Sign of the power factor according to the four-quadrant rule (§4.2.12):
Quadrant 1 : Power factor PF sign + (inductive system)
Cos Φ sign +
Quadrant 2 : Power factor PF sign - (capacitive system)
Cos Φ sign -
Quadrant 3 : Power factor PF sign + (inductive system)
Cos Φ sign -
Quadrant 4 : Power factor PF sign - (capacitive system)
Cos Φ sign +
Specific characteristics in MAX/MIN mode (from 10Hz to 1kHz):
• Uncertainties: add 1% R to the values in the tables above.
• Capture time: approximately 100ms.
