3.10 POWER MEASUREMENTS W, VA, VAR, PF AND DPF
This measurement is possible en single-phase or in balanced three-phase.
Reminder : in DC or AC+DC power measurement, first correct the DC zero in
current (see § 3.8.2, step 1)
For the power factor (PF), the displacement power factor (DPF) and the powers VA
and var measurement is possible only in AC or AC+DC.
3.10.1 Measurement of single-phase power
1. Set the switch to
;
2. The device automatically displays AC+DC. To select AC, DC, or
AC+DC, press the
key until the desired choice is reached.
3. Connect the black lead to the COM terminal and the red lead to " + ";
4. Place the test probes or the crocodile clips of the black lead on the
neutral (N), then those of the red lead on the L phase.
5. Clamp only the corresponding conductor, respecting the direction;.
