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 error
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).
