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 error
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.

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.
