3.9 Power factor calculation (PF)
With the clamp configured in power measurement (switch on position
W
) and correctly connected (see § 3.8),
perform a short press on the yellow key: the power factor is displayed.

3.10 Frequency Measurement (Hz)
This function is active for measurements V, A, W in AC. For the power function, the frequency measurement is
performed on the voltage signal.
1.
Perform a short pressing on the Hz key, the display shows the frequency of the measured signal.
2.
Pressing again returns to the previously displayed measurement.

3.11 Phase order indication
This measurement is performed with 2 cables only, sequentially as follows:
1.
Integration of a reference period on one phase L1-L2 for example
2.
Integration of a reference period on one phase L1-L3
3.
Calculation of the time delay between reference and measurement periods enabling determination of the phase
order or phase rotation direction.
