3 - Histograms page
Description
The Histograms:
• This is the default start page (open when switched on).
• Shows the histogram of the voltage and current measurements, acquired in real time by
the release.
Components of the page
The page appears as follows:

Figure 69
The following table provides a description of the various areas of the page:
Pos. Description
A
Histogram ordinate, with the measurements expressed as percentages of the
nominal values set.
B
Bars that represent the measurements of phase-to-phase voltages U12 U23 U31,
and of the phase currents L1 L2 L3 and of the neutral Ne:
• In blue: no alarm.
• In yellow: voltage or current in prealarm, compared with the thresholds set (see
the chapter "9 - Touch protections" from page 84, and the chapter "10 - Measuring
Pro protections" from page 96).
• In red: voltage or current in alarm, compared with the thresholds set (see the
chapter "9 - Touch protections" from page 84, and the chapter "10 - Measuring
Pro protections" from page 96).
C
Abscissa of the histogram.
NOTE:
• The references of the voltages are shown with the Ekip Measuring
accessory module.
• The Ne current reference is shown with circuit-breaker configured with
neutral.
D
Signalling and functions in progress:
•
Remote connection, visible with auxiliary voltage and Ekip COM accessory
modules.
•
or Auxiliary voltage or Test connection.
•
or If the Dual Set function is enabled (see the Settings menu), the
letter identifies the active configuration.
E Current time.
F
• Measurement of the maximum phase current, as an absolute value (Ampere).
• Phase to which the measurement refers.
