Remote Wind Sensor
For best results and accurate readings, the wind sensor should be mounted onto a mast to allow the wind to travel around the sensor unhindered from all directions (ideal mast size should be from Ø16mm – Ø33mm). Due to the design of this product it is important to mount the sensor so that the front (marked E) is pointing in East-West direction.
Mounting the wind sensor onto a mast
Firstly carefully remove the packaging and protection from the wind sensor head and check that wind-fan and weather-vane can rotate freely before fixing the unit using the supplied screws. For basic mounting the wind sensor must be pointing exactly in an East-West direction in order to provide an exact Eastern reference point to the base station’s compass otherwise wind direction will be wrongly represented.
Czyli musisz tak zamocować sensor wiatru, ażeby przód z literką E wskazywał kierunek Wschód-Zachód.
Chyba innego sposobu nie ma.
