Setup
1. Battery Installation
The Kestrel 5500FW requires one AA battery for operation. Ensure the battery is inserted with the correct polarity as indicated inside the battery compartment.
- Open the battery compartment cover on the back of the device.
- Insert one AA battery, matching the positive (+) and negative (-) terminals.
- Securely close the battery compartment cover.

2. Compass Calibration
Calibrating the compass is crucial for accurate wind direction, headwind, crosswind, and ballistic measurements. Calibration is required after changing the battery, updating firmware, or changing geographical locations. It is also recommended every 2-3 weeks for optimal accuracy. If the display shows "***" for direction, recalibration is needed.
- Press the "gear" button to enter the main menu.
- Scroll to "SYSTEM" using the arrow buttons and press the center button to select.
- Scroll to "COMPASS CAL." and press the center button.
- The screen will prompt you to "Hold Kestrel upright. Rotate slowly for 30 seconds."
- Press the center button to start the calibration.
- Slowly rotate the Kestrel meter one full turn every 6 seconds for 30 seconds, keeping it upright and away from any metal objects.
- Once "Cal Complete" appears, the compass is calibrated.
Troubleshooting Compass Calibration: If "Cal Failed" appears, try calibrating in a different location. If the issue persists, perform a soft reset by removing the battery, holding down the power button for 30 seconds, then reinserting the battery and attempting calibration again.

3. Bluetooth LiNK Connection
The Kestrel 5500FW features Bluetooth LiNK for wireless data transfer to iOS and Android devices. This allows for real-time monitoring, data logging, and alerts via the Kestrel LiNK app.
- Download the Kestrel LiNK app from your device's app store.
- Ensure Bluetooth is enabled on your Kestrel meter (check system settings).
- Open the Kestrel LiNK app and follow the on-screen instructions to pair your device.
- Once connected, you can view live data, configure settings, and download logged data.

2. Key Measurements
The Kestrel 5500FW accurately monitors and displays various environmental parameters:
- Wind Speed/Air Speed: Measured by the impeller.
- Temperature: Ambient air temperature.
- Humidity: Relative humidity.
- Heat Stress Index: A critical measure for safety in hot environments.
- Wet Bulb Temperature (Psychrometric) & Naturally Aspirated Wet Bulb Temperature.
- Barometric Pressure & Station Pressure (Absolute Pressure).
- Altitude (Barometric) & Density Altitude.
- Dew Point Temperature & Vapor Pressure Deficit (VPD).
- Wind Chill.
- Compass Direction, Crosswind, Headwind/Tailwind: Requires calibrated compass.
- Pressure Trend.
- Fire Weather Specifics:
- Probability of Ignition (PIG): Indicates the likelihood of a fire starting.
- Fine Dead Fuel Moisture (FDFM): Measures moisture content in fine fuels, crucial for fire behavior prediction.

Maintenance
Proper maintenance ensures the longevity and accuracy of your Kestrel 5500FW meter.
- Cleaning: Wipe the device with a soft, damp cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the Kestrel in a cool, dry place when not in use. If storing for extended periods, remove the battery to prevent leakage.
- Battery Replacement: Replace the AA battery as needed. Always recalibrate the compass after battery replacement.
- Firmware Updates: Periodically check the Kestrel Instruments website or the Kestrel LiNK app for available firmware updates to ensure your device has the latest features and performance enhancements.
- Durability: The Kestrel 5500FW is waterproof (IP67 rated) and drop-tested (MIL-STD-810F), designed to withstand harsh outdoor conditions. However, avoid unnecessary exposure to extreme impacts or submersion beyond its rated depth.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Compass displays "***" or "Cal Failed" | Compass requires calibration or interference from metal objects. | Perform compass calibration as described in the Setup section. Ensure you are away from metal objects. If calibration repeatedly fails, perform a soft reset (remove battery, hold power for 30s, reinsert battery) and try again. |
| Device does not power on | Dead or incorrectly installed battery. | Replace the AA battery with a fresh one. Check battery orientation. |
| Bluetooth LiNK not connecting | Bluetooth not enabled on Kestrel or mobile device, or app issue. | Ensure Bluetooth is enabled on both the Kestrel and your mobile device. Restart the Kestrel LiNK app. Try re-pairing the device through the app. |
| Inaccurate readings | Sensor obstruction, environmental factors, or calibration needed. | Ensure the impeller and other sensors are clear of debris. Calibrate the compass if wind direction is affected. Allow the device to acclimate to new environmental conditions. |
