Basic Weather Station BWS-200
6
A spade and/or shovel
A pickaxe
A concrete trowel
Sufficient concrete mix for a 300mm square x 600mm deep hole (including
water supply etc. if mixing concrete on site)
A spirit level
Install the mast as follows:
1.
Locate a suitable position for the weather station. Ensure that the ground
consistency is not too loose, and will be able to support the mast and concrete
foundation.
2.
Dig a hole at least 300mm square by 600mm deep (see Figure 2).
3.
Fit the ‘anti-spin’ bar into the hole towards the lower end of the mast, and
secure in place with the two nuts supplied.
4.
Set the SPM2 Mast into the centre of the hole and temporarily pack it with
suitable material so that it is vertical.
5.
Mix the concrete and pour into the hole removing any temporary packing. It
is very important to ensure that the mast is vertical – periodically
check with
a spirit level
and make adjustments as necessary. Double check that the mast
is vertical before the concrete starts to cure.
6.
Allow at least 24 hours for the concrete to cure properly before attempting to
fit the instrumentation.
