22. At any time it will be possible to analyze the current
recording status by pressing the MENU key. The following
information will be shown:
 Starting date and time of recording
 The value set for the integration period
 The number of periods elapsed from the beginning of the
recording
 The remaining memory capacity for recording

23. Now it is possible to bring the unit SOLAR-02 near the PV strings to measure irradiation and
temperature by means of the relevant probes. When the distance between unit SOLAR-
02 and MPP300 does not allow the RF connection, on the display of SOLAR-02 the
symbol “
” flashes for approx. 30s and then disappears. Unit MPP300 steadily
searches for the RF connection with unit SOLAR-02.
24. Position the reference cell onto the surface of the PV modules. Please refer to the relevant
User Manual for a correct assembly.
25. Put the temperature sensor in contact with the rear side of the module and fasten it with
some tape; prevent touching it with your fingers (as this could alter the measure).
26. Wait for a few seconds to allow the probes to reach a steady measure and then connect the
irradiation probe to input PYRA/CELL and the temperature probe to input TEMP of unit
SOLAR-02.
27. Wait for the message “READY” to appear on the display of SOLAR-02 to indicate that the
unit has detected the data with solar irradiation > minimum threshold set (see § 5.1.5).
28. With the message “READY” shown on the display, wait for approximately 1 minute in
order to take a certain number of samples.
29. Disconnect the irradiation and temperature probes from unit SOLAR-02 and bring the unit
near unit MPP300. Bring the main unit SOLAR I-V near MPP300 too. The three units must
be near each other (max distance 1m).
30. The main unit SOLAR I-V must be in EFF mode; if no flashing symbol “
” appears, press
key
 to activate the RF connection search again.
31. Press key
 on SOLAR-02 to activate the RF connection again. Consequently, the main
unit will show the message “active radio connection”.
