EN - 54
6.3.4. Fast check IVCK with irradiance measurement
CAUTION
 The maximum voltage among inputs P1, P2, C1 and C2 is 1000V DC. Do not
measure voltages exceeding the limits expressed in this manual.
 The maximum current allowable for the instrument is 10A. 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-V400 or SOLAR I-V
 Measurement through reference cell connected to SOLAR-02 under RF to I-V400 or
SOLAR I-V
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 IVCK

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.
