6.3.2. Preliminary settings
1. Turn the instrument on by pressing ON/OFF key.
2. Press ESC/MENU to display the main menu.
3. Select “I-V” and press ENTER to enter the FV module performance measurement section.
In general when selecting I-V from main menu the instrument shows automatically the
last mode under use (I-V or IVCK).
4. In case the current mode is not IVCK, press ENTER,
select “Measurement ” by means of arrow keys
(
,).Use the arrow key  to enter the internal
submenu, select “IV Check” and confirm by ENTER to
start up the initial screen of rapid test IVCK.

6. Use the arrow keys (
 , ) to select the module type
among the ones stored inside the instrument’s database
(see § 5.3.1)
7. Use the arrow keys (
,), select “Mod. per Str” and
use the arrow keys (
 , ) to enter the number of
modules for the string under test. The maximum number
of modules to be set is 50
8. Use the arrow keys (
,), select “Temp” and use the
arrow keys (
 , ) to select the measurement type of
the module temperature among the modes:

 “Auto”  automatic measurement carried out according to the measured open circuit
voltage value of modules (recommended method)
 Manual  entering the known value for the module temperature in the corresponding
field “Value”
 Aux  temperature measurement with probe
Note: Settings for parameter “Rs” are ignored for measurements type IVCK.
9. Use the arrow keys (
,), select “Tol Voc” and “Tol Isc” then use the arrow keys ( , )
to set the tolerance values for open circuit voltage (Voc) and short circuit current (Isc)
provided by the module manufacturer (values allowed: +0% .. +25%). Please note that the
instrument’s uncertainty is indicated in brackets beside the above mentioned values and it
will be added to the value entered to get the outcome (OK/NO).
10. Press SAVE to store the measurements effected or ESC/MENU to quit without saving.
