Improving the accuracy of the barometric altimeter on the Huawei Watch Ultimate involves several steps and configurations. Here's how you can enhance its performance:
1. Calibration: The first step is to calibrate the altimeter. To do this, go to an open area, open the Barometer app, swipe up to access the Altitude screen, and touch Calibrate. Stay in the same place for 2 to 3 minutes to allow the device to calibrate properly[9]. If your GPS positioning is accurate, you can also calibrate by starting an outdoor workout in an open area and exercising for more than 5 minutes[9].
2. Enable Online Altitude Calibration: Ensure that Online altitude calibration is enabled for the Compass app. This feature helps maintain accuracy by updating the atmospheric pressure benchmark over the internet. To enable it, open the Compass app, touch the three-dot menu in the upper right corner, and select Online altitude calibration[10].
3. Regular Updates: Keep your watch updated to the latest software version. Updates often include improvements to sensor accuracy and performance[10].
4. Environmental Considerations: Be aware that environmental factors such as weather changes or being in enclosed spaces (like high-rise buildings or airplanes) can affect accuracy. Recalibrate the altimeter after significant changes in environment or when returning to a stable location[9].
5. Sensor Maintenance: Ensure that the watch's ports and sensors are free from debris or moisture, as these can interfere with sensor accuracy[5].
6. Comparison with Other Devices: For optimal accuracy, compare your watch's readings with other reliable instruments like GPS devices or survey markers. This helps in identifying any discrepancies and allows for adjustments to be made accordingly[4].
By following these steps and configurations, you can significantly improve the accuracy of the barometric altimeter on your Huawei Watch Ultimate.
