HT MPP300 Manuel D'utilisation page 15

21. Upon reaching the instant "00" after pressing the GO/STOP
key, the test is started and the three units are
synchronized with each other. In these conditions:

The display of SOLAR I-V shows the message "rec.
running"

The display
"Recording..."

On MPP300, the STATUS LED flashes green
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
Press the ESC key to exit the screen
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 panel 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 the User
Manual of SOLAR I-V)
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 "
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 "radio connection activated"
of SOLAR-02 shows the message
