4.5.2.3 Maintenance
There are no user-serviceable parts on the 2-D Sonic Wind Sensor. Keep the
transducer paths clear of any obstructions. When clearing the transducer paths,
do not remove the “rubber” caps on each of the transducers.
4.5.2.4 Calibration
Recalibrate the 2-D Sonic Wind Sensor annually. Obtain an RMA number
before returning this sensor to Campbell Scientific for recalibration.
