2. Preparation: Installation Base
Prepare the installation base for mounting the Sunshine Duration Meter, according to the verified orientation
in above step.
Mounting without the Base Plate (optional)
1) There are mounting holes already provided on the bottom side of the Sensor Stand as shown in
below figure. Prepare the holes corresponding to the drawing on the mounting stage in the
correct orientation (see above step for how to check the orientation of North/South direction).
2)
Place the Sunshine Duration Meter on the mounting stage in the correct orientation and fix it with 2
fixing screws (M5) attached.
Mounting on the Base Plate (optional):
When optional Base Plate is used, install it on the installation base in the following procedure.
NOTE: Below procedure explains the installation in Northern Hemisphere. In case of installation in
Southern Hemisphere, the North and South would be in opposite positions.
1)
First draw a line on the mounting base in the direction of North/South direction. There are 2 fixing
holes provided on the Base Plate; use the hole on South side as the starting point of the line.
(See previous section for determining the North/South direction)
2)
Attach the Sensor Stand on the Base Plate in advance. Place the Base Plate with Sensor Stand
on the mounting base so that the N side of the North/South indicator of the Base Plate is facing
towards North and match the position of holes on the Base Plate and the fixing holes.
The hole on the North side of the Base Plate is shaped wider; adjust the Base Plate position so that
the North/South line drawn in earlier step comes in the center of this wide hole.
3)
Insert the fixing bolts in the fixing holes and fasten enough that the bolts does not come off.
4)
Level the Base Plate using leveling feet; the air bubble in the spirit level should be positioned within
the center circle.
5) Fasten the bolts securely as making sure the level and North/South orientation of the Base Plate
are maintained.
6)
After the bolts are tightened securely, check the level and North/South orientation of the Base Plate
once again.
3. Mounting the Sunshine Duration Meter
Place the main unit of the Sunshine Duration Meter in the North/South orientation on the installation base
(optional Base Plate) which is prepared in the step 1 and 2 above.
Adjust the Latitude Scale Plate to the appropriate position for the installing site and fasten the fixing bolt on
the Latitude Scale Plate.
