2. Mount a crossarm to a tripod or tower.

3. If a pyranometer is also being mounted on the crossarm, orient the crossarm north-south
with the Nu-Rail on the end farthest from the equator. Otherwise, the crossarm may be
oriented north-south, east west, or any other angle desired.
(p. 20) contains detailed information on determining true north by using a
compass and the magnetic declination for the site.
4. Secure the 12-inch aluminum pipe to the Nu-Rail fitting.
5. Place the 03002 on the pipe, and orient the sensor crossarm North-South with the vane to
the North.
6. Tighten the mounting post band clamp. Final sensor orientation is done after the data
logger has been programmed to measure wind direction as described in
7. Use the torpedo level to ensure that the sensor is level.
8. Route the sensor cable along the underside of the crossarm to the tripod or tower, and to
the instrument enclosure.
9. Secure the cable to the crossarm and tripod or tower by using cable ties.
The 03002 can also use a CM221 Right-Angle Mounting Kit or CM216 Sensor Mounting Kit; see
the following figures. The CM221 uses U-bolts to secure the sensor to a crossarm. The CM216
mounts the sensor on top of a CM106B, CM110, CM115, or CM120 tripod. The CM216 extends
10 cm (4 in) above the mast of the tripod.
