7. 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 tolerance values
set on the instrument).
8. 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. The value of insulation resistance is shown in field
“Rp” (parallel resistance between values R+ and R-) 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).
9. With continuity measurement selected, the instrument
goes on by opening the short-circuit and carrying out the
test between terminals E and C. 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).
10. The message “Result OK” is finally shown by the
instrument in case the result of all performed tests is
positive.

In general, the result of a test on a Voc and Isc measurement is determined by the
following relationships:
Please note the following parameters:
= average of open voltage calculated over last 10 measurements saved
= average of short-circuit current calculated over last 10 measurements saved
= positive tolerance value on Voc = x
= negative tolerance value on Voc = x
= positive tolerance value on Isc = x
= negative tolerance value on Isc = x
= maximum instrument error declared on Voc (see § 0)
= maximum instrument error declared on Isc (see § 0)
= error on Voc measurement @ OPC
= error on Isc measurement @ OPC
The following conditions on parameters on the measurement result are managed by the
instrument:
