9. Press ENTER key, select the “Settings” item and confirm
again with ENTER to access the next screen which allows
setting the type of PV module and the number of modules
relative to the PV string under test.

10. By means of arrow keys (
,) select the type of PV
module included in the database of meter (§ 5.3.1).
11. By means of arrow keys (
,) select the item “N. of
Mod.” and by means of arrow keys (
,) set the number
of modules of the PV string under test. The maximum
number of modules is 50
12. By means of arrow keys (
,) select the “Rs” item and by
means of arrow keys (
,) choose the “Manual” or “Auto”
mode for the serial resistance measurement (§ 6.2.4)
13. By means of arrow keys (
,) select the type of PV
module included in the database of meter (§ 5.3.1). By
means of arrow keys (
,) select the “Temp” item and
by means of arrow keys (
,) choose the type of module
temperature among the modes listed:
 Auto”  automatic measurement performed by the
meter depending on the measured value of open
voltage of the modules (recommended method)
 “Manual”  setting of a module temperature value by
the operator on the corresponding “Value” field
 “Aux”  setting of temperature of module performed by
auxiliary probe

15. Mount the M304 (inclinometer) supplied accessory, place and hold it on the plane of module.
Verify that the sun shadow falls on the disc within the “limit internal circle” on the
disc itself (see Fig. 7b). If this is not the case, the incidence angle between sun rays
and the module surface is too high and not complying with the test conditions
declared by the module manufacturer. As a consequence the measurements
performed by the meter are not ok and all measurements steps shall be repeated at
another daytime
16. Fix the support of the cell to the module by using the supplied set of screws and mount the
reference cell on it possibly with output terminals downwards with respect to the
module. Rotate the cell upwards to lean it on the small wing of the support so as the cell is
perfectly parallel to the plane of module, then fix it with the relevant screws supplied
17. Connect the output of reference cell (depending on the type of module under test) of
reference cell at the IRR. input of meter by using the cable supplied with the cell
18. Connect, if used, the auxiliary temperature probe (optional accessory) to the AUX input
of meter and on the rear of module, fixing it with adhesive tape
