The following table provides a description of the various areas of the page:
Pos. Description
Histogram ordinate, with the measurements expressed as percentages of the
A
nominal values set.
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
B 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).
Abscissa of the histogram.
NOTE:
C • 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.
Signalling and functions in progress:
• Remote connection, visible with auxiliary voltage and Ekip COM accessory
modules.
D
• 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.
• Measurement of the maximum phase current, as an absolute value (Ampere).
F
• Phase to which the measurement refers.
