5.2. REAL TIME VALUES
Fig. 18: MENU GENERAL screen - Real time values section
In this section the real time measured values of parameters both on input channels and
internally calculated are shown by meter. In particular the following are shown:
1. AC TRMS voltages, currents and all kind of electrical parameters for any single phase
and total, Flicker values and voltages Unbalanced.
2. Voltage and current waveforms for any single phase and total.
3. Voltage and current harmonics up to 49th component for any single phase and total
both in numerical and histograms graphical format in absolute or percentage value with
respect to each fundamental signal.
4. Vectorial diagrams of each voltage and current with the respective phase angles in
order to define the correct nature of system loads under test.
Further in this manual the expression “Page x/y” will be used, to indicate that the current page
number (x) and the total number of pages (y) depend on the instrument settings. Pressing
cyclically F1 key or arrow keys left of right the meter shows the other pages of TRMS
measured values which are described in below pictures. Pressing ESC key to go back to
