22. At any time while recording it will be possible to
analyze its current status by selecting the button
Saved data management in the GENERAL
MENU. The following information will be shown:
a. starting date and time of recording
b. the value set for the integration period
c. the number of periods elapsed from the
beginning of the recording
d. 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 SOLAR300N
user's manual).
28. With the message "READY" shown on the display, wait for a time period at least equal to the
set integration period (see SOLAR300N user's manual) in order to take a significant number
of samples (>=2).
29. Disconnect the irradiation and temperature probes from unit SOLAR-02 and bring the unit
near unit MPP300. The two units must be near each other (max distance 1m).
30. Connect (if disconnected) the SOLAR300N unit to the MPP300 unit. The MASTER LED
must always be flashing to indicate the connection between SOLAR300N and MPP300.
31. Press key  on SOLAR-02 to activate the RF connection again. Consequently, the
REMOTE LED on unit MPP300 will start flashing.
