Ultrasonic Wind Sensor WMT703 Maintenance
WARNING
Some WMT703 product versions provide heating for transducers and/or
array arms. To avoid injury, do not touch the heated parts of the wind
sensor when the heating is enabled.
CAUTION
When handling WMT703, do not rotate, pull, strike, bend, scrape or
touch the transducers with sharp objects. Any impact on the wind sensor
array damages the device.

Periodic Maintenance
WMT703 is a very reliable and rugged sensor. Since no moving or
consumable parts are used, no periodic maintenance is required.
WMT703 has been calibrated at the factory, and you are not required to
perform recalibration.
NOTE
Periodic calibration of WMT703 is not required for technical reasons.
However, some quality management systems may require regular
calibration of the measuring instruments.
To fulfill these requirements, it is recommended that you recalibrate the
wind sensor every 24 months. Contact Vaisala Service Center for more
information (see www.vaisala.com/services/servicecenters.html.).
