automatic measurement performed by the meter depending on the
measured value of open voltage of the modules
(recommended method)

setting of a module temperature value by the operator on the
corresponding “

16. 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
17. 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
18. Connect the output of reference cell (depending on the type of module under test) of
reference cell at the
