Note (1) - Display of O.L above 1500 kvar in single-phase (1000 V x 1500 A).
- Bandwidth in AC in voltage = 3 kHz, in current = 2 kHz
Notes (2), (3) , (4), 5, 6 and (8) of the previous § apply.
- Specific characteristics in MAX/MIN mode in power
(from 10Hz to 1kHz in AC
and AC+DC):
•
Uncertainties: add 1 %R to the values in the tables above.
•
Capture time: approximately 100ms
4.2.19 Calculation of the power factor (PF)
Measurement range (1)

measurement range
50 to 100% of the
measurement range
Uncertainties (7)

± (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.
Remark : The PF is always positive
- 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.
