INSTALLATION & MAINTENANCE
Installation consists of attaching the unit to a mast via the supplied mounting pole. If a crossarm is used,
the entire unit can be bolted to a mast or attached via U-bolts.
The sensor is dynamically calibrated at the factory and due to the nature of its operation should not require
field calibration. Calibration is a matter of proper orientation during installation. A magnetic compass is
recommended for proper orientation. Field maintenance should include occasional cleaning of the vane
assembly and inspection of the internal mechanism to make sure it is free from insects and debris. In some
applications users may need to occasionally verify and document sensor accuracy with a calibration dial/
vane. Possible bearing and potentiometer replacement every three to five years is recommended to main-
tain low starting threshold.
