2.5.3. MODE BUTTONS
These buttons display specific modes:
Button
Function
Waveform acquisition mode, with two sub-modes: transients mode (blackouts, interference, etc.) and
inrush current mode (starting of motor).
Harmonic graphs display mode: representation of voltage, current, and power harmonics, order by
order; determination of harmonic currents produced by nonlinear loads, analysis of problems caused
by harmonics according to their order (overheating of neutrals, conductors, motors, etc.).
Waveform display mode: display of voltage and current waveforms, display of minima and maxima
of summary tables, determination of phase rotation.
Alarm mode: list of recorded alarms exceeding selected thresholds; recording of network blackouts
with half-cycle resolution (Vrms, Arms, Urms), determination of energy consumption overshoots,
monitoring of compliance with a power supply quality contract.
Trend mode: recording of selected parameters.
Power/energy mode: display of power and energy measurements.
Three buttons are real-time mode buttons:
In each of these modes, colored circles on a white background (for example
saturation; the circle background is colored when the channel measured is potentially full (for instance
When the circle corresponds to a simulated channel (for example in 4-wire three-phase with selection V1V2, 2½-element method, or in
3-wire three-phase with selection A1A2, 2-element method; see connections in §4.6), this channel is potentially full if at least one channel
used in calculating it is potentially full.
Similarly, if the circle corresponds to a phase-to-phase voltage channel, it is potentially full if at least one of the phase- to-neutral
voltage channels used in calculating it is potentially full.
