5. Funcionament
Once powered on, the B-Qtech U1 Inclinometer will automatically begin to acquire GPS signal and display data. The unit features two main buttons for interaction:
- Establir clau: Used to enter settings menus and confirm selections.
- Clau d'inici: Used to cycle through display modes or adjust values within settings.
Refer to the "Display Modes and Functions" section for details on specific data readings.
6. Display Modes and Functions
The U1 Inclinometer provides various data points crucial for driving, especially off-road:
6.1. Velocímetre
Displays real-time vehicle speed. The GPS-based speed measurement offers high accuracy.
6.2. Roll Angle Display
Indicates the vehicle's lateral tilt (left or right slope). The display shows angles from -40° to +40°. Exceeding 40° may indicate a rollover risk.

Figure 6.1: Illustration of Roll Angle (lateral tilt) and Pitch Angle (front-to-back tilt) displays.
6.3. Pitch Angle Display
Shows the vehicle's longitudinal tilt (uphill or downhill slope). The display ranges from -40° to +40°. A warning is indicated if the slope exceeds 40°.
6.4. Battery Voltmeter
Monitors the vehicle's battery voltage in real-time (DC 5V-30V range, 0.5V accuracy). This helps prevent issues like breakdowns or starting problems due to low voltage, and self-ignition from high voltage.

6.5. Satellite Time
Displays the current time synchronized via GPS satellites.
6.6. Brúixola
Provides accurate heading direction using GPS satellite positioning technology, overcoming magnetic interference.
6.7. Altitude and Coordinates
Displays current altitude and high-precision latitude and longitude coordinates, useful for navigation and tracking.

7. Warnings and Alerts
The B-Qtech U1 Inclinometer includes safety features to alert drivers:
- Overspeed Warning: An alarm sounds if the vehicle speed exceeds a preset limit (e.g., 120 km/h or 74.5 mph).
- Alerta de fatiga de conducció: The device will remind you to take a break after approximately 4 hours of continuous driving.
- Excessive Angle Warning: An alarm will sound if the roll or pitch angle exceeds 30 degrees, indicating a potential rollover or hazard.

9. Solució De Problemes
If you encounter issues with your B-Qtech U1 Inclinometer, refer to the following common solutions:
- Sense alimentació/pantalla:
- Ensure the power cord is securely connected to both the inclinometer and the vehicle's cigarette lighter socket.
- Check if the cigarette lighter socket is receiving power (test with another device).
- Verifiqueu que el contacte del vehicle estigui engegat.
- No GPS Signal/Incorrect Readings:
- Assegureu-vos que el vehicle estigui a l'aire lliure amb una llum clara view of the sky. GPS signal acquisition may take a few minutes, especially on first use or after a long period of inactivity.
- Avoid placing the unit under metallic objects or tinted windows that may block GPS signals.
- If the compass or angle readings seem off, ensure the unit is placed on a level surface and away from strong magnetic fields. The device performs automatic calibration.
- Display Brightness Issues:
- The unit features automatic brightness adjustment. Ensure the light sensor on the unit is not obstructed.
- Botons que no responen:
- Assegureu-vos que la unitat estigui encès.
