XIII. Supplemental Wind Vane Calibration Adjustment
Your anemometer/wind vane has been factory-calibrated to
correctly indicate wind direction when installed per the instructions
on p. 19, and should not require recalibration. However, if you
wish to adjust wind direction readings after installation (to correct
a difference between display readings and actual wind direction)
without physically realigning the sensor, you may use the following
procedure.
1.
Perform when you have a fairly steady breeze from
a known direction.
2.
Press
and
simultaneously to display the
wind vane correction constant (the keyboard
initially has a correction constant of zero).
3.
Press and hold
or
to adjust the wind vane
correction constant. After approximately 3 seconds
the wind vane correction will start changing.
Increase the constant if you want the direction
diamond on the display to move counter-clockwise
to match actual wind direction. Decrease the
constant if you want the direction-indicating
diamond to move clockwise to match actual wind
direction.
4.
Repeat Step 4 as necessary until the wind direction
is correctly displayed. Record the Wind Vane
Correction Constant below.
5.
Press any function key to leave this operation and
retain the correction constant that is displayed.
NOTE:
The correction constant is a number from 0 through 255.
Each digit represents approximately 1.4 angular degrees of
correction (360 ÷ 256) that is added to the uncorrected wind
direction.
