5. Operating Instructions
Power On/Off:
- To Turn On: Short press the ON/OFF button. The LCD display will light up.
- To Turn Off: Press and hold the ON/OFF button for approximately 3 seconds. The device will also automatically shut off after 3 minutes of inactivity to conserve battery.
Measurement Modes (Absolute/Relative):
The device offers two measurement modes:
- Absolute Measurement (ABS): This mode measures the angle relative to a true horizontal plane (0°). The 'LEVEL' indicator will be displayed.
- Relative Measurement (ZERO): This mode allows you to set any surface as a temporary 0° reference point.
To Switch Modes: Short press the ZERO button. The 'LEVEL' indicator will appear for absolute mode and disappear for relative mode.
Unit Conversion:
The device can display angles in degrees (°) or percentage (%).
- To Switch Units: Short press the TILT% button to toggle between degrees and percentage.
Hold Function:
To freeze the current measurement on the display:
- Short press the HOLD button. The 'HOLD' indicator will appear on the screen.
- To release the hold and resume live measurement, short press the HOLD button again.
Magnetic Base Usage:
The strong magnetic base allows the device to attach securely to metallic surfaces, providing hands-free operation and stability during measurements.

6. Calibration
For optimal accuracy, it is recommended to calibrate the device periodically or if you suspect inaccurate readings.
Calibration Procedure:
- Turn off the device.
- Press and hold down the ZERO button.
- While continuing to hold the ZERO button, press the ON/OFF button to power on the device.
- "CAL1" will appear on the screen.
- Place the device on a stable, flat, and level surface.
- Follow the on-screen prompts (CAL1, CAL2, etc.) and rotate the device 180 degrees as instructed, ensuring it remains on a stable surface.
- Once calibration is complete, the display will show 0.00°.
Important Note: During calibration, the surface should be stable and level. The inclination of the surface should not exceed 3 degrees, and the position of each calibration step should be consistent.

7. Maintenance
- Clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Store the device in a dry place, away from dust and direct sunlight.
- Remove batteries if the device is not used for an extended period to prevent leakage and damage.
8. Troubleshooting
- Device not functioning properly: Check the battery level and replace if necessary. Try resetting the device by removing and reinserting the batteries.
- Inaccurate readings: Recalibrate the device following the steps in Section 6. Ensure the device is placed on a stable, level surface during measurement. Be aware that temperature fluctuations, humidity, or extreme conditions can affect accuracy over time.
- "Err" displayed: This typically indicates that the device is tilted forward or backward more than 30 degrees, exceeding its optimal measurement range for certain functions. Adjust the device's position.
