Appendix A.  Wind Direction Sensor 
Orientation 

A.1  Determining True North and Sensor Orientation 

Orientation of the wind direction sensor is done after the datalogger has been 
programmed, and the location of True North has been determined.  True North is 
usually found by reading a magnetic compass and applying the correction for 
magnetic declination; where magnetic declination is the number of degrees 
between True North and Magnetic North.  The preferred method to obtain the 
magnetic declination for a specific site is to use a computer service offered by 
NOAA at 

www.ngdc.noaa.gov/geomag

.  Magnetic declination can also be 

obtained from a map or local airport.  A general map showing magnetic 
declination for the contiguous United States is shown in FIGURE A-1. 

Declination angles east of True North are considered negative, and are subtracted 
from 360 degrees to get True North as shown FIGURE A-2 (0° and 360° are the 
same point on a compass).  Declination angles west of True North are considered 
positive, and are added to 0 degrees to get True North as shown in FIGURE A-3.  
For example, the declination for Logan, Utah is 14

°

 East.  True North is 360

°

 - 

14

°

, or 346

°

 as read on a compass. 

Orientation is most easily done with two people, one to aim and adjust the 
sensor, while the other observes the wind direction displayed by the datalogger. 

1.  Establish a reference point on the horizon for True North. 

2.  Sighting down the instrument center line, aim the nose cone, or 

counterweight at True North.  Display the input location or variable for wind 
direction using a hand-held keyboard display, PC, or laptop. 

3.  Loosen the U-bolt on the CM220 or the set screws on the NU-RAIL that 

secure the base of the sensor to the crossarm.  While holding the vane 
position, slowly rotate the sensor base until the datalogger indicates 0 
degrees.  Tighten the set screws.
