8.3 Measurement menu
After completing the auto-acquisition procedure (refer to
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
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
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

The display fields relating to the Measurement Menu are: the numerical value (area highlighted in red) including three
and the indication on the type of load (inductive or capacitive), as well as the wording
Should measurement not be available (due to a current 0.7% lower than the CT Secondary
winding parameter
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].
