TAIL ASSEMBLY
The tail piece must be assembled to the vane shaft before installing the sensor.* Locate the tail piece
(packed with this manual). Remove the blue tape from the shaft and save the two screws stored there.
Slide the tail piece into the slot in the shaft and align the screw holes. Secure the tail with two screws
using a #1 Phillips screwdriver.

INSTALLATION
NOTE:
Wind direction sensors are usually aligned to true north, rather than magnetic north. True north
is usually found by reading a magnetic compass and applying the correction for magnetic declination.
On-line calculators are available to enter your location and obtain the correction factor. One such
website is:
https://www.ngdc.noaa.gov/geomag-web/#declination
1.
Loosen the two mounting screws on the base of the sensor.
2.
Place the sensor on the top of the mast or mounting stub.
3.
Align the north indicator label to geographic (true) north.
4.
Tighten the mounting screws using moderate torque.
The PVC jacket of the cable will last for many years outdoors under normal circumstances. In harsh
environments it may be necessary to protect the cable with conduit.
