Figure 8: Sensor package mounting diagram
Note
Beside the antenna, there is an arrow icon with "WEST" words (Figure 9) representing the di-
rection of west. The sensor body has to be adjusted so that the "WEST" indication is facing to
real west direction in your location. A compass device is recommended to help adjust direction.
Permanent wind direction error will be introduced when the outdoor sensor is not installed in
right direction.
Figure 9
Now look at the bubble level. The bubble should be fully inside the red circle. If it is not, wind
direction, speed, and rain readings may not operate correctly or accurately. Adjust the mounting
pipe as necessary. If the bubble is close, but not quite inside the circle, and you cannot adjust
the mounting pipe, you may have to experiment with small wooden or heavy cardboard shims
between the sensor package and the top of the mounting pole to achieve the desired result (this
will require loosening the bolts and some experimentation).
Make sure you check, and correct if necessary, the westly orientation as the final installation
step, and now tighten the bolts with a wrench.
RESET BUTTON AND TRANSMITTER LED
Using a bent-open paperclip, press and hold the RESET BUTTON (see Figure 10) to affect a
reset: the LED turns on while the RESET button is depressed, and you can now let go. The LED
should then resume as normal, flashing approximately once every 48 seconds.
