16. When Voc and Isc measurements are complete, the
message “OK” is shown in case the result of the test is
positive (measured values within the tolerances set on the
instrument)
17. With insulation measurement selected, the instrument
goes on with the test keeping terminals P and N short-
circuited, and carrying out the test between this point and
terminal E for the time necessary to obtain a steady value.
18. The value of insulation resistance is shown in field “Ri” and
the message “OK” appears in case the result of the test is
positive (measured value higher than the minimum limit
value set on the instrument).

19. With continuity measurement selected, the instrument
goes on by opening the short-circuit and carrying out the
test between terminals E and C.
20. The value of resistance in the continuity test is shown in
field “Rpe” and the message “OK” appears in case the
result of the test is positive (measured value lower than
the maximum limit value set on the instrument).
21. The message “Outcome:OK” is finally shown by the
instrument in case the result of all performed tests is
positive.

22. Press the arrow key
to show the following page in
which the values of parameters Voc and Isc are shown. It
shows:
The module being used
The value of irradiance
The value of temperature of the module
The average values of Voc and Isc under OPC
The values of Voc and Isc measured under OPC
The values of Voc and Isc calculated under STC and
the relevant partial results obtained by comparison with
the nominal values.

The rated values of Voc and Isc are the values found in the instrument’s internal
modules’ DB (see § 5.6).
