3.3 Outdoor Sensor Package Assembly
3.3.1 Install U-bolts and metal plate
Slide the U-bolts into the metal plate on the underside of the integrated wireless sensor and
screw the nuts from the other side so that the bar on which the integrated wireless sensor is
placed can be inserted into this hole.
Figure 4: U-Bolt installation
The plate and U-Bolts are not yet needed at this stage but doing this now may help avoid
damaging wind vane and wind speed cups later on. Handling of the sensor package with wind
vane and speed cups installed to install these bolts is more difficult and more likely to lead to
damage.
3.3.2 Install wind vane
Push the wind vane onto the shaft on the top side of the sensor package, until it goes no further,
tighten the set screw, with a Philips screwdriver (size PH0). Make sure the wind vane can rotate
freely. The wind vane’s movement has a small amount of friction, which is helpful in providing
steady wind direction measurements.
Figure 5: Wind vane installation diagram
The wind direction section on the main unit display shows the letters N (North), E (East), S
(South) and W (West). The integrated wireless sensor must be oriented so that the arrow
marked “North” on the top of the wireless sensor is pointing north. If the integrated wireless
sensor is oriented incorrectly, wind direction measurement will be inaccurate.
