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.
