9. The initial screen under IVCK mode displays the values
of:
 Module under use
 The average values of Voc and Isc under OPC conditions.
 The value of Voc measured under OPC conditions

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.
10. Press GO/STOP to start the test. In case of no error
conditions, the instrument displays the screen with results
as shown sideways. It displays as follows:
 The module under use
 The average values of Voc and Isc under OPC conditions
 The values of Voc and Isc measured under OPC and
relative partial outcome resulting after comparing the
average values. In general:

11. 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.
NOTES on displayed AVERAGE VALUES
The average values of Voc and Isc are displayed on the outcome page. Such values
include the average values of Voc and Isc under OPC conditions calculated as mean of
the last 10 tests previously saved. If the user effected and saved a number of tests <10 or
he reset the average values (see 6.3.5) the average value displayed during test N+1 will
be calculated on N available values.
