Installation

Prior to installation it is important to find a suitable location for the
rain gauge. In the first instance one should look for a setting where
the measuring cannot be interfered with by obstacles. A useful rule
of thumb is to position the rain gauge at a height that is at least twice
that of nearby obstacles. In the case of special applications it is
possible that there may be other special requirements. Secondly, it is
important for the rain gauge to be placed in a horizontal position. Also
look for a location where the stand for the rain gauge can be placed
in a stable and horizontal position.
Choosing the right measuring location is of great importance as far as obtaining accurate
measuring results is concerned
First of all the stand for the meter must be placed in a
stable and horizontal position. This will require drilling a
hole in the soil in which to place the tube of the stand.
After putting the tube in position place the leftover soil
back into the hole and tamp it down well while holding
the tube in an upright position. Place the fixing platform of
the stand on top of the tube and finish by securing it with
socket-head screws.
The rain gauge is now completely disassembled, after
which it is reassembled step by step back on the stand:
1. Place the outer base plate with the three fixing holes on
the platform on the stand.
2. Place the inner base plate with the recesses on the outer base plate. The
recesses need to fit correctly into the studs while it must be ensured that
the inner base plate cannot be pushed up by the connecting cable.
3. Align both base plates with the aid of the adjustable rings of the stand.
4. Check the horizontal position with a spirit level that is fixed to the inner base plate.
5. Secure the outer base plate by screwing the wing nuts on the stud bolts of the stand.
6. Assemble the rain gauge.
