Appendix C. Wind Direction Sensor Orientation
C-3
1.
Fully install your weather station and establish communications with the
datalogger.
2.
Establish a reference point on the horizon coinciding with
True North
.
3.
Sight down the centre line of the direction sensor and aim its nose cone at this
reference point.
4.
Display the value for wind direction using the Monitor Mode of PC200W if
using RS232 Direct Link to a laptop computer to view the reading.
5.
Loosen the
lower
‘orientation’ fitting band clamp on the Wind Sentry arm so
that it can be rotated by hand. (Do
not
loosen the upper clamp).
6.
While holding the vane in the correct (true north) position at all times,
carefully rotate the bracket until the datalogger indicates 0 degrees. (This
procedure will require some care as the whole sensor body will move with the
arm.)
7.
Fully re-tighten the band clamp, ensuring that the datalogger reading (0
) is
unchanged.
Once set up as described above, the complete Wind Sentry can be removed from
the mount by loosening the
upper
band clamp only. The spigot in the mounting
device will ensure that it is replaced in the correct orientation.
