This menu allows the user to monitor main power quality parameters.
The first page displays the outcome of the EN50160 compliance test (Reference
Standard for power quality), according to the parameters selected in the Setup Menu.
A test is performed to check whether frequency, voltage, harmonic voltage distortion,
and unbalance comply with the above-mentioned reference Standard and the nominal
values which have been set.
A table also shows the number of interruptions, dips and swells which have occurred
during the period monitored.
