6. Operating Instructions
6.1 Monitoring Temperatures
- Insert the probe tip into the thickest part of the meat, avoiding bone or gristle.
- The current temperature for each connected probe will be displayed on the thermometer's LCD screen and within the INKBIRD app.
- The LCD screen features stepless dimming for its backlight. Adjust the brightness as needed for optimal visibility in various lighting conditions.

6.2 Using the Smart App
- Preset Menus: The app offers 29 preset cooking programs for various types of meat and doneness levels. Select a preset for quick setup.
- Custom Settings: You can manually set target temperatures and cooking times for each probe.
- High/Low Temperature Alarms: Set upper and lower temperature limits. The thermometer will alert you if the temperature goes outside this range, helping to prevent overcooking or undercooking.
- Temperature Pre-Alarms: Configure a pre-alarm to sound when the food temperature is a few degrees away from your target, allowing you to prepare for removal.
- Count-up/down Timers: Utilize the integrated timers for precise cooking duration management.
- Temperature History Graph: View real-time temperature changes and access up to 72 hours of offline data stored on the device. The app provides unlimited data storage for long-term tracking.


7. Care and Maintenance
- Cleaning Probes: After each use, clean the probe tips with warm soapy water. Wipe them thoroughly with a clean cloth. Do not immerse the probe connectors or the main thermometer unit in water.
- Cleaning Main Unit: Wipe the main unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Storage: Store the thermometer and probes in a clean, dry place when not in use. Remove batteries if storing for extended periods to prevent leakage.
- Probe Care: Avoid bending the probe cables sharply or exposing them to open flames directly, as this can damage the insulation and internal wiring.
8. Troubleshooting
- Q: The thermometer is not turning on.
- A: Check if the AA batteries are inserted correctly with the right polarity. Replace with new batteries if necessary.
- Q: Cannot connect to the app via Bluetooth.
- A: Ensure Bluetooth is enabled on your smartphone. Make sure the thermometer is within the 260ft/80m range. Try restarting both the thermometer and your phone, then attempt to pair again. Ensure no other devices are interfering with the Bluetooth connection.
- Q: Inaccurate temperature readings.
- A: Ensure the probe is inserted into the thickest part of the meat and not touching bone or gristle. Check if the probe cable is damaged. You can calibrate the temperature within the app if you suspect a consistent offset (calibration range: Β±7β/Β±12β).
- Q: No alarms are sounding.
- A: Verify that alarms (high/low temperature, pre-alarm) are correctly set in the INKBIRD app. Check your phone's notification settings to ensure the app is allowed to send alerts.
9. User Tips
- For optimal accuracy, always insert the probe into the center of the thickest part of the food, avoiding bones.
- Utilize the 29 preset menus in the app as a starting point, then customize them based on your specific cooking preferences and recipes.
- Take advantage of the temperature pre-alarm feature to avoid rushing and ensure your food is removed at its peak doneness.
- Regularly check the temperature history graph in the app to learn and refine your cooking techniques for consistent results.
