The following keys are active on this page:

 The F1 key (or the PAG item on the display) advances to the following page of

saved values.

 The ESC key (or the smart icon on the display) to exit the function and go back

to the “Recording analysis” page (Fig. 143).

In this page, the following symbols are used:

Patt  System total Active Power

Preatt  Total Reactive Power

Papp  Total Apparent Power

Pf  Total Power Factor

CosPhi  System total CosPhi

CosPhi represents the theoretical limit value which

can be reached by the Power factor if all harmonics

are eliminated from the electrical system. For

dimensioning a power factor correction system,

reference is usually made to the CosPhi parameter

value.
