    ® SPECIAL FUNCTIONS User Screens The Kestrel Meter has three User Screens that can be customized to display three current measurements simultaneously. These screens can also be turned off. (See the Main Menu section for setup instructions.) Max/Avg for Wind Speed & Wind Chill The Max/Avg values for the wind speed and wind chill values are measured independently from the stored and charted data.

  • Page 10 - Ideally, provide an airflow of at least 1 M/S (2.2 MPH), over the temperature sensor—point the Kestrel Meter into the airflow. If there is no airflow, simply wave the unit back and forth so air passes over the sensors. With airflow over the temperature sensors and humidity chambers, readings within specifications will be provided within two to three minutes, even after a large temperature shift.
  • Page 11 When reviewing stored data, remember that changes in pressure AND changes in location/altitude will affect the stored values. When tracking pressure changes relative to weather, set the reference altitude on the BARO screen and keep the Kestrel Meter in one location. Your graph history will now show trends in...
