If external voltage is detected on the test terminals the
instrument will check if conditions are appropriate for
proceeding with the test. Appropriate notifications are
displayed.
Conditions for starting the test (regarding external voltage on
test terminals):

Consider correct environmental conditions and PV module
data! Otherwise, nominal and STC data will be wrong / will
not be calculated!
Hint
In case that wrong PV module data were used and (STC, nominal) results are wrong,
the instrument enables to change the PV module after the test.
See chapter Changing PV modules and other parameters in already performed
measurements.
