Description
The maximum and minimum currents are the recordings of the measurements of the maximum
and minimum phase currents performed by the release, and that can be displayed by selecting
I Max and I Min in the menu History - Measurements.
The interval between one measurement and the other can be set through the parameter
Measurement interval, available in the menu History.
The recordings can be reset through the command Reset measurements, available in the
menu History - Measurements.
Correlated information
Every measurement is correlated by the following information:
• The time interval since the previous measurement.
• The phase to which it refers, and value in Amperes.
• The date and time (referring to the internal clock).
• Graphical representation in the form of a histogram on a time axis.
NOTE:
• If the value is less than 0.03 In, "..." is shown instead of the value in Amperes.
• The graphical representation is in reference to 1 In, with a maximum value of 1.25
In
• When the parameter "Measurement interval" is modified, the release performs a
recording immediately.

The measurements are expressed as a ratio between the peak values and RMS values, for
each individual phase.
