CHAPTER 8
MAINTENANCE
This chapter contains information that is needed for performing visual
inspection, cleaning, and verifying the operation of WMT700.
WARNING
Some WMT700 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 WMT700, 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
WMT700 is a very reliable and rugged sensor. Since no moving or
consumable parts are used, no periodic maintenance is required.
WMT700 has been calibrated at the factory, and you are not required to
perform recalibration.
NOTE
Periodic calibration of WMT700 is not required for technical reasons.
You can use the WM Verifier to test the mechanical integrity of the
device and perform one-point calibration.
However, some quality management systems may require regular
calibration of the measuring instruments.
To fulfill these requirements, Vaisala recommends that you recalibrate
the wind sensor every 24 months. Contact Vaisala Service Center for
more information.
