7.4.5. NEUTRAL MAX.-MIN. DISPLAY SCREEN
This screen displays the RMS values and the positive and negative peaks of the neutral relative to earth.
Column of voltage values.
RMS: true RMS voltage.
PK+: maximum peak voltage
since the instrument was turned
ON or since the last time the
button was pressed.
PK-: minimum peak voltage
since the instrument was turned
ON or since the last time the
button was pressed
7.5. SIMULTANEOUS DISPLAY
The
sub-menu displays all of the voltage and current measurements (RMS, DC, THD, CF, PST, PLT, 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.
THD: total harmonic distortion with the fundamental RMS
value as reference (%f) or with the total RMS value without
CF: peak factor calculated over 1 second.
7.5.2. 4V SIMULTANEOUS DISPLAY SCREEN
This screen displays the RMS, DC, THD, CF, PST and PLT values of the phase-to-neutral voltages and of the neutral.
Column of RMS and DC values along with the CF and the
Column of voltages simple (phases 1, 2, and 3).
RMS: true RMS value calculated over 1 second.
THD: total harmonic distortion with the fundamental RMS
value as reference (%f) or with the total RMS value
CF: peak factor calculated over 1 second.
PST: short-term flicker calculated over 10 minutes.
PLT: long-term flicker calculated over 2 hours.
DC: DC component.
DC as reference (%r).
THD (%r) concerning the neutral.
DC: DC component.
without DC as reference (%r).
