of Weather.com or Wunderground.com), and set your weather
station to match the official reporting station.
Wind Speed Calibration
In the calibration mode, press the SET button again and the
wind speed value will flash (the default is 1.00).
Press the CHANNEL/+ key or MAX/MIN/- key to adjust the
wind speed calibration factor from 0.75 to 1.25, where:
Calibrated Wind Speed = Calibration factor x Measured Wind
Speed
Press and hold the CHANNEL/+ or MAX/MIN/- key for three
seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.
Note: The wind gust is also affected by the wind speed
calibration factor.
Discussion: Wind speed and wind gust are adversely
affected by installation constraints. The rule of thumb is to
install the weather station four times the distance of the height
of the tallest obstruction (for example, a 6 m house would
require an installation 24 m away).
In many instances, due to trees and other obstructions, this is
not possible. The wind speed calibration allows you to correct
for these obstructions.
