Fig. 9: Connection for IVCK test with irradiance measurement through SOLAR-02

14. In the initial screen of IVCK mode, the following values

are displayed in real time:

 Module  type of module being tested

 Vdc  value of output voltage from module/string

 Irr  irradiance (from a direct measurement or

SOLAR-02 connected via RF)

 Tc  modulo temperature (in MAN or AUX mode) and

the relevant measuring mode, or “- - -” in AUTO mode

 In case, the symbol “ ” of RF connection with

SOLAR-02

CAUTION

Upon pressing the GO/STOP key, different error messages can be displayed

by the instrument (see § 6.6) and, therefore, the test cannot be started. Check

and eliminate, if possible, the problem causing the error message before going

on with the test.

15. Press GO/STOP to start the test. In case no erro

conditions occur, the instrument displays the message

“Measuring…” and the measure of open-circuit voltage

between the terminals P and N and of short-circuit current

(for Isc values 10A).
