Displacement Power Factor (DPF) Calculation
4.2.20
Measurement Range (1)
0.00 to +1.00
Specified Measurement Range
(from 1A
AC
)
0 to 100% of the measurement range
Accuracy (2) (3)
± (5% R +2cts)
Resolution
0.01
Note (1)
If one of the terms in the calculation of the DPF is displayed as "OL", or
forced to zero, the display of the DPF is an indeterminate value "----".
Note (2)
of the previous § apply
Note (3)
Measurement stabilization ~8 sec
NOTE:
The DPF is always positive. It is equivalent to |cos
Φ

Specific characteristics in MAX/MIN mode (from 10Hz to 1kHz):
Uncertainties: add 1% R to the values in the table above.
Capture time: approximately 100ms.

4.2.21.2 Current
Measurement Range (1)
5.0 to 1999Hz
Specified Measurement Range
1 to 100% of the measurement range
Accuracy
± (0.4% R + 1ct)
Resolution
0.1Hz
Note (1)
In MAX/MIN mode, the operating range is limited to 1kHz.
If the level of the signal is too low (<10% of the range, or V<8V or
I<9A) or if the frequency is less than 5Hz, the device cannot
determine the frequency and displays "----".
Specific Specifications in MAX/MIN mode (from 10Hz to 1kHz):
Accuracy: add 1% R to the values of the table above.
Capture of the extreme: approximately 100ms.
