7.5. SIMULTANEOUS DISPLAY
The sub-menu displays all of the voltage and current measurements (RMS, DC, THD, CF, PST, FHL and FK).
7.5.1. 3U SIMULTANEOUS DISPLAY SCREEN
This screen displays the RMS, DC, THD, and CF values of the phase-to-phase voltages.
Column of phase-to-phase voltages (phases 1, 2, and 3).
RMS: true RMS value calculated over 1 second.
DC: DC component.
THD: total harmonic distortion with the fundamental RMS value as reference (%f)
or (for the C.A 8333 only) with the total RMS value without DC as reference (%r).
CF: peak factor calculated over 1 second.

7.5.2. 3V SIMULTANEOUS DISPLAY SCREEN
This screen displays the RMS, DC, THD, CF and PST values of the phase-to-neutral voltages.
Column of voltages simple (phases 1, 2, and 3).
RMS: true RMS value calculated over 1 second.
DC: DC component.
THD: total harmonic distortion with the fundamental RMS value as reference (%f)
or (for the C.A 8333 only) with the total RMS value without DC as reference (%r).
CF: peak factor calculated over 1 second.
PST: short-term flicker calculated over 10 minutes.

7.5.3. 4A SIMULTANEOUS DISPLAY SCREEN
This screen displays the RMS, DC (only if at least one of the current sensors can measure direct current), THD, CF, FHL and FK
values of the phase and neutral currents.
Column of RMS values and (if the current sensor allows) DC values along with the
CF concerning the neutral.
Columns of current values (phases 1, 2 and 3).
RMS: true RMS value calculated over 1 second.
DC: DC component.
THD: total harmonic distortion with the fundamental RMS value as reference (%f)
or (for the C.A 8333 only) with the total RMS value without DC as reference (%r).
CF: peak factor calculated over 1 second.
FHL: harmonic loss factor. For the oversizing of transformers to allow for harmonics.
FK: K factor. Derating of the transformer as a function of the harmonics.

Note: To make it possible to adjust the zero of current sensors measuring DC, the DC values are never cancelled.
