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
Press the ESC key to exit the screen.
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 SOLAR02
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.
28. After the automatic data transfer phase, the instrument will display:

Do not show any results if do not exist on the PV installation a
“stable irradiance ” condition more than the minimum irradiance
threshold

Display the best performance values if during the recording, the
Irradiance values reached the “
stable
” condition and its values
were higher than the minimum irradiance threshold

Unable to carry out the analysis if irradiance has never
reached a steady value higher than the minimum threshold set,
or if no value exists which is valid during the whole recording
(nDC > 1.15).
29. Press SAVE to save the results obtained (see § 7.1) or ESC to exit the screen and go
back to the initial screen.
