determining True North using a compass and the magnetic declination for
the site.
7. Remove the alignment screw at the base of the 034B (FIGURE 4-1).
8. Insert the 034B into the aluminum bushing provided with the sensor (see
FIGURE 4-1).
9. Align the hole in the bushing with that in the 034B base and replace the
screw (see FIGURE 4-1).
10. Insert the 034B/bushing into the NU-RAIL fitting (FIGURE 4-1) or the
CM220’s U-bolt (FIGURE 4-2).
11. Align the sensor so that the counter weight points to true South and tighten
the set screws on the NU-RAIL or U-bolts on the CM220. Final sensor
orientation is done after the datalogger has been programmed to measure
wind direction as described in Appendix C.
12. Remove the shoulder screw to allow the vane to rotate (see FIGURE 4-1).
13. Attach the sensor cable to the six pin male connector on the 034B. Make
sure the connector is properly keyed. Finger tighten the knurled ring.

tower, and to the instrument enclosure.
15. Secure the cable to the crossarm and tripod or tower using cable ties.
