Then the radiometer is mounted in the CVF4 and levelled with its own levelling feet. Afterwards the radiometer mounting screws
and shoulder washers are fitted (not secured yet).
In case the CVF4 is mounted on a solar tracker, finish the alignment of the tracker first before securing the radiometer screws
because tracker (and radiometer) levelling might need re-adjustment.
After all mounting screws have been secured the cables of the CVF4 and the radiometer can be connected. The radiometer cable
goes (down) through the slit in the CVF4 base plate.
Finally the CVF4 cover can be put on and the two cover nuts can be fastened.
Make sure the cover is horizontal (check equal space around the radiometer dome) and the two cover nuts are fastened hand tight.
