9. Connect irradiance probes and temperature probe (if necessary) according to previous

pictures and to effected settings (see § 6.3.2).

10. In the initial screen of IVCK mode the following values are

displayed:

 Module under use

 Irradiance (through direct measurement or SOLAR_02 under

RF connection)

 The temperature value (if mode MAN or AUX) and

corresponding measurement mode. If mode AUTO ”- - -“

 The average values of Voc and Isc under OPC conditions

The following values acquired in real time are also displayed:

 Open circuit voltage

 Any symbol of RF connection with SOLAR-02

CAUTION

When pressing the GO/STOP key the instrument can provide different error

messages (see §6.3) and, as direct consequence, not carry out the test. Check

and eliminate, if possible, causes of the problems before continuing the test.

11. Press GO/STOP to start up the test. In case of no erro

conditions, the instrument displays the screen with the

following results:

 The module under use

 The irradiance value

 The cell temperature value

 The average values of Voc and Isc under OPC

 The values of Voc and Isc measured under OPC

 The values of Voc and Isc measured under STC and relative

partial outcome resulting after comparing the rated values.

The rated values of Voc and Isc are the values of the DB built-in modules (see §5.3)

 The overall value of outcome:

o OK: if all results under STC are OK,

o NO if one of the results under STC is NO

12. Press SAVE to store the test result into the instrument’s memory (see §7.2) or press

ESC/MENU to quit without saving and go back to main measurement screen.
