3.2. Taking Measurements

For accurate wind measurements, ensure the impeller is exposed to the airflow. For temperature and humidity, allow the device to acclimate to the environment for a few minutes. The Kestrel 5500 measures the following parameters:

• Wind Speed
• Wind Direction
• Wind Chill
• Air Temperature
• Water Temperature
• Snow Temperature
• Relative Humidity
• Heat Stress Index
• Dew Point Temperature
• Wet Bulb Temperature
• Station Pressure
• Barometric Pressure
• Altitude
• Density Altitude

4. Calibration

4.1. Compass Calibration

Compass calibration is essential for accurate wind direction, crosswind, and headwind/tailwind readings. It should be performed after changing batteries, updating firmware, or relocating to a new geographical area. It is also good practice to calibrate every 2-3 weeks.

1. From the main screen, press the 'Gear' button to enter the menu.
2. Scroll to 'System' and press the center button.
3. Scroll to 'Compass Cal.' and press the center button.
4. Follow the on-screen instructions: Hold the Kestrel upright and rotate it slowly for 30 seconds, keeping it away from any metal objects.
