22. The instrument displays:

Vdc = DC output voltage from module/string.

Irr = irradiance measured by supplied reference cell

Tc = temperature of module. The herewith options are
available for this field:
 AUTO  automatic mode of temperature measurement
 Number  MAN or AUX mode of temp. measurement
 “ - - - “  AUX mode with no connected probe

Module = type of selected module

Temp = measurement mode of module temperature

Start = measurement activation mode

The symbol “ ”
fixed
at display means that a stable
RF connection is established with the SOLAR-02

CAUTION
At the press of
GO/STOP
key some different error messages can be
displayed by the meter (see § 6.3) and, due of this, the test cannot start.
Check and remove, if possible, this error message before start the test
23. Press
GO/STOP
key (in Manual activation mode) to start
the test. If none of the previous error messages are
detected, the message “
Measuring…
” is shown on the
display for some seconds, depending on the level of
power during test.

24. At the end of test, the values of typical parameters (all
referred to a single module in standard conditions STC)
are shown by the meter together with the final response (§
6.2.3) based on the automatic calculation performed and
relevant to:

Translation of I-V curve to STC condition

Verification of tolerance % of the maximum power
declared by the manufacturer.
