7.4.2 Mounting the wind monitor atop a tripod mast

The wind monitor mounts on top of a CM106B, CM110, CM115, or CM120 tripod by using the
CM216 (see FIGURE 7-4 (p. 14)). The CM216 extends 10 cm (4 in) above the mast of the tripod.

8. Sensor maintenance

Every month do a visual/audio inspection of the anemometer at low wind speeds. Verify that the
propeller and wind vane bearing rotate freely. Inspect the sensor for physical damage.
Replace the anemometer bearings when they become noisy, or the wind speed threshold
increases above an acceptable level. The condition of the bearings can be checked by using the
Propeller Torque Disc as described in the R.M. Young manual (see
www.youngusa.com/products/7/).
The potentiometer has a life expectancy of fifty million revolutions. As it becomes worn, the
element can produce noisy signals or become non-linear. Replace the potentiometer when the
noise or non-linearity becomes unacceptable. The condition of the vertical shaft (vane) bearings
can be checked by using R.M. Young Vane Torque Gauge.
