Setting Up The Rain Sensor; Setting Up The Anemometer (Wind Sensor) - Bresser 4CAST PC Mode D'emploi

2.2.2 SETTING UP THE RAIN SENSOR

1. Unlock the funnel-shaped top of the rain sensor by turning both knobs on the sides of the
rain sensor in an anti-clockwise direction.
2. Lift the top off the base and insert 2 x UM-3 or "AA" size 1.5V batteries into the battery
holder.
3. Replace the lid and secure into place by turning the knobs clockwise.
4. Place the rain sensor in a location such that precipitation can fall directly into the sensor,
ideally 2-3 ft above the ground.
It may be secured into place by using the four screws provided.
5. The sensor must be accurately level for optimum performance. To check if the sensor is
level, remove the lid and check if the ball bearing inside is at the midpoint of the leveler.
Additionally, a bubble level or carpenter's level may be used.
6. Attach the protective screen onto the top of the lid. The screen will prevent any debris
entering the sensor.
PLACEMENT TIPS:
• The rain sensor should be placed in an open area away from walls, fences, trees and other
coverings which may either reduce the amount of rainfall into the sensor, deflect the entry of
wind-blown rain, or create extra precipitation runoff. Trees and rooftops may also be sources
of pollen and debris.
• 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.

2.2.3 SETTING UP THE ANEMOMETER (WIND SENSOR)

1. Assemble the wind cups to the anemometer arm.
2. Attach the assembled anemometer to the base.
3. Insert 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.
