2.5.3. MODE KEYS (VIOLET KEYS)
These give access to specific modes:
Item Function See
Waveform acquisition mode, with two sub-modes: transients mode (blackouts, interference,
etc.) and inrush current mode (starting of motor).
§ 5
Harmonic curves 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.).
§ 6
Display of voltage and current waveforms, display of minima and maxima of summary tables,
determination of phase rotation.
§ 7
Alarm mode: list of recorded alarms exceeding the thresholds programmed in the configuration;
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.
§ 8
Trend mode: recording of the parameters selected in the Configuration menu. § 9
Display of power and energy measurements § 10
Three keys are real-time mode keys: , and .
In each of these modes, the coloured circles on a white ground , in which the channel numbers or types are entered, are indi-
cators of saturation: the ground of the circle is coloured when the channel measured is potentially full .
When the identification disc corresponds to a simulated channel (for example in 4-wire three-phase with selection V1V2, 2½-ele-
ment 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 saturation disc 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.
2.5.4. OTHER KEYS
The other keys have the following functions:
Item Function See
Configuration key. § 4
Snapshot of current screen and retrieval of screens already stored. § 11
Help key: provides information about the functions and the symbols used for the current dis-
play mode.
§ 12
