Figure 108 Margin Verifier
Combined Wind Sensor
Periodic Maintenance
Testing Proper Operation
It is recommended to check the ball bearings of the anemometer and the
vane every year. If the cup wheel or the vane is not rotating smoothly or
it creates detectable noise, the bearings must be replaced.
Replacing Consumables
Only a trained technician should replace the bearings.
NOTE
Some random data samples may be lost during the zero verifier test.
This, however, does not indicate that the sensor is faulty.
