8.3 Measurement menu
After completing the auto-acquisition procedure (refer to Chap. 6), after every power-up and after 2 minutes of activity
in any page (excluding those of the Current Alarm Menu), the controller will automatically move to the first page of the
Measurement Menu. You can also go back to the Measurement Menu from any other menu by pressing key for
more than 2sec.
The Measurement Menu includes a page devoted to each one of the following measurements: cosphi, reactive
power, current, voltage, frequency, active power, apparent power, THDI%, THDV%, power factor and temperature.
Now press one of keys , or to scroll the pages or one of keys or
to scroll pages back.
NOTE. the measurements of reactive power, current, voltage, active power and apparent power are set by
default with RMS values; to display only the essential components (at 50 or 60Hz, based on network frequency) achieved
through the harmonic analysis, set to "ON" the parameter P.14 – Displaying of values from harmonic analysis inside
the Advanced Setting Menu in Chap. 7.6.
The display fields relating to the Measurement Menu are: the numerical value (area highlighted in red) including three
digits, the dot if necessary, the sign and the indication of the inductive or capacitive
load, and the measuring unit and/or type of measurement (area highlighted in blue).
The icons of the other fields can be present and, as a whole provide controller
general status. For the detailed description of the single icons, refer to Chap. 8.2 -
Display and key description.
NOTE: should the measurement to be displayed not be valid or out of range, the “-
--“ value will be displayed.
The first displayed page is the one relating to the cosphi that will include the numerical value
and the indication on the type of load (inductive or capacitive), as well as the wording “cosφ”.
Should measurement not be available (due to a current 0.7% lower than the CT Secondary
winding parameter Chap. 7.1.2) the controller will show “---“.
The next page relates to the reactive power, which is recognisable by the measurement unit in
[VAr].
The next page relates to the current, which is recognisable by the measurement unit in [A].
The next page relates to the voltage, which is recognisable by the measurement unit in [V].
