15. Upon reaching “00” after pressing the GO/STOP key, the
test is started and the two units are synchronized with
each other. In these conditions the message “Recording
running…” is displayed on the main unit and
“Recording…” is displayed by SOLAR-02.

16. 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 (IP)
 The number of periods elapsed from the beginning of the
recording
 The remaining memory capacity for recording

17. 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 the unit SOLAR-
02 and PVCHECK does not allow a RF connection, on the display of SOLAR-02, the symbol
“
” flashes for approx. 30s and then disappears, while PVCHECK continues searching
for the connection for approx. 1 minute.
18. Position the reference cell onto the surface of the PV modules. Please refer to the relevant
User Manual for a correct assembly.
19. Put the temperature sensor in contact with the rear side of the module and fasten it with
some tape; avoid touching it with your fingers in order not to alter the measurement result.
20. 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.
21. 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).
22. With the message “READY” shown on the display, wait for approximately 1 minute in
order to take a certain number of samples.
23. Disconnect the irradiation and temperature probes from unit SOLAR-02 and bring the unit
near PVCHECK (max distance 1m).
24. The main unit PVCHECK must be in EFF mode. If there is no flashing symbol “ ”,
press key
 to activate the RF connection search again.
25. Press key
 on SOLAR-02 to activate the RF connection again. Consequently, the main
unit will show the message “active radio connection”.
26. To stop testing, press the GO/STOP key on the instrument and confirm with ENTER that
you want to stop recording.
27. The display of the unit SOLAR-02 will display the message “SEND” to indicate that the data
will be transferred to the main unit.
