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 again three times and
the rain value will flash (the default is 1.00).
Press the CHANNEL/+ 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 CHANNEL/+ or MAX/MIN/- key for three
seconds to increase or decrease rapidly.
Press the ALARM key to reset current value.

based on the funnel diameter. The bucket tips every 0.01" of
