corresponding to two to four times the height of any nearby obstruction.
- It is important that rain excess can flow freely away from the sensor.
Make sure that water does not collect at the base of the unit.
- The rainfall measurement mechanism utilizes a magnet, hence do not
place any magnetic objects around the proximity of the sensor.
Setting up the Anemometer (wind sensor)
1. Assemble the wind cups and wind vane to the anemometer arm
2. Attach the assembled anemometer to the base.
3. Insert two 2 x UM-3 or “AA” size 1.5V batteries into the battery holder in the
base.
4. Mount the anemometer onto a vertical surface, using the fittings provided.
5. To allow the main console unit to find the direction which the wind vane is
oriented, the following procedures are required:
i. Insert the batteries
ii. Point the wind vane towards the north. Use a compass or map if
necessary.
iii. Use a pin to press the “SET” key which is in the battery compartment of the
wind sensor.
Note: Above procedure must be repeated for changing battery.
The “SET” will toggle the direction between two mode:
1. Let the wind direction as manufacturer design. It will be as a default setting
after
2. Set the current direction as NORTH.
Placement tips:
- Check that wind can travel freely around the anemometer and is not
distorted by nearby buildings, trees or other structures.
- For better results, place the anemometer at least 3m above local
structures and obstacles. The ground creates a frictional effect to wind flow and
will attenuate readings.
- Aim for maximum exposure of the anemometer to the commonest wind
directions in your area.
- The official mounting location for anemometers is 10m (33 ft) above
ground level in a clear unobstructed location.
Setting up the Main Console Unit
1. Open the latch at the back of the main console unit.
2. Insert 4 x UM-3 or “AA” size 1.5V batteries according to the polarities shown.
