2. UNPACKING AND ASSEMBLING
Instruction manual CM 121 9
2.2 CM 121C
Packed in the CM 121C transport box are the same items as with the CM 121B plus:
z
CV 2 adapter
z Two spacers
z Two cap screws M6 x 10
z Two cap screws M5 x 16
After removing the ties with which the items are connected to the transport box, the shadow ring can
easily be assembled.
z
Place the pillar in between the base and the crossbar, using the thread
z Place the CV 2 adapter (see figure 1.2)
z Place the shadow ring on its sliding bars using two screws
z Insert the sliding bars in the crossbar. The correct way is when the pyranometer
sensor with CV 2 can be positioned along the axis of the ring
Caution
before you start mounting the CM 121C you have to secure the base a surface
otherwise the CM 121C can fall over.
Caution:
Please note that the screw that connects the pyranometer support with the crossbar
must never be touched because it defines the position of the pyranometer sector relative
to the sliding bars and the shadow ring. The sector must be in the center of the ring and
this is adjusted in the factory. The particular screw is protected by a cap.
