5.5. Start a test on PV system
For testing purposes, no setting of the recording parameters is necessary, but only of
those relevant to the configuration of the analyzer (see § 5.3.2).
The test can only be activated by pressing the F1 key (RUN) in GENERAL MENU
 Real
time values screen. By accessing this screen, the values measured by the instrument will
immediately be displayed in real time. If the SOLAR-0x unit is connected too, the
temperature and irradiation values, measured by means of the external probes connected
to it, will also be available.
Furthermore, the acronym MPPT (Multiple Power Point Tracker) shall indicate the
characteristic of the DC/AC converter (inverter), capable of maximizing the DC power
which can be taken from the photovoltaic field (see the § 10.3 for further details), the
acronym PRp shall indicated the Performance ratio (evaluated on active powers).

After connecting to the SOLAR-0x or MPP300 (optional) unit and pressing the F1 key (see
the test procedure described in par. 7.1 and 7.3), the instrument will enter the stand-by
mode, waiting for recording, and then the recording-in-progress mode. The stand-by and
recording-in-progress modes are signalled by certain icons in the display’s top part, as
shown in the herewith pictures:

CAUTION
It is recommended to always start recording by connecting the instrument to
the external supply, provided with the instrument, in order not to loose any
data during the whole measurement campaign.
