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 6m(20ft) house would require an installation 24m(80ft) 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.
In addition to installation challenges, wind speed bearings (any moving part)
wears over time. To correct for wear, the correction value can be increased
until the wind cups must be replaced.
Without a calibrated source, wind speed is a difficult parameter to measure.
We recommend using a calibrated wind meter and constant, high speed
fan.
Rain Calibration
In the calibration mode, press the
SET
button three times and the rain
value will flash (the default is 1.00).
Press the
C
key or
MAX/MIN/-
key to adjust the rain calibration
factor from 0.75 to 1.25, where:
Calibrated Rain = Calibration factor x Measured Rain
Press and hold the
C
or
MAX/MIN/-
key for three seconds to
increase or decrease rapidly.
Press the
ALARM
key to reset current value.
