6.3.4. Fast check IVCK with irradiance measurement
CAUTION
The maximum voltage among inputs P1, P2, C1 and C2 is 1000V DC (for I-
V400w and SOLAR I-Vw) or 1500V (for I-V500w and SOLAR I-Ve). Do not
measure voltages exceeding the limits expressed in § 10.2
The maximum current allowable for the instrument is 15A. Do not effect tests in
parallel on FV module strings.
Never effect tests on modules or FV strings connected to DC/AC converter.
1. Turn on the instrument pressing
ON/OFF
2. Irradiance measurement can be carried out just through the following modes:
Measurement through reference cell directly connected to I I-V400w, I-V500w, SOLAR
I-Vw or SOLAR I-Ve
Measurement through reference cell connected to SOLAR-02 under RF to I-V400w, I-
V500w, SOLAR I-Vw or SOLAR I-Ve
Check that the remote unit SOLAR-02 setting is consistent with the type of
measurement to be effected (see §5.1.4).
3. Check the minimum irradiance value set in the “irradiance” section (see § 5.1.5).
4. Go back to main MENU and select “I
-V
”
5. Select “
I-V
” and press
ENTER
to enter the FV module performance measurement section.
Generally when selecting
I-V
on general menu the instrument automatically shows the last
mode under use (I-V or IVCK).
6. In case the current mode is not IVCK, press
ENTER
,
select “
Measurement
” by means of arrow keys
(
,
). Use the arrow key
to enter the internal
submenu, select “
IV Check
” and confirm pressing
ENTER
to start up the initial screen of fast check

7. Check the preliminary settings based on descriptions of § 6.3.2
8. Connect the instrument to the module/string under test as shown in the following
picture. In particular connect the negative pole of the module/string to terminals P1, C1
and it positive pole to terminals P2, C2. In
Auto
activation mode is recommended the
use of KITKELVIN optional accessory
