CHAPTER 4
MAINTENANCE
This chapter provides information that is needed in basic
maintenance of the product.
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.
If your sensor includes the alignment sleeve and the factory
alignment has not been altered, you can simply remove and
remount the sensor to its place with the plastic collar
without realigning.
