5.2 Powering On/Off
- To Power On: Press and hold the main control button (center button) for a few seconds until the display lights up.
- To Power Off: Press and hold the main control button again for a few seconds. The device also features an auto-off function after 180 seconds of inactivity to conserve battery.
6. Operation
The ATuMan LS6 offers 19 measurement functions. Familiarize yourself with the control buttons and display icons for efficient use.
6.1 Basic Measurement (Distance)
- Ensure the device is powered on.
- Point the laser emitter towards the target surface.
- Press the main control button once to activate the laser beam.
- Press the main control button a second time to take the measurement. The distance will be displayed on the screen.
6.2 Measurement Modes
The device supports various measurement modes. Use the side button(s) to cycle through the available modes. The current mode will be indicated on the display.
- Continuous Measurement: Provides real-time distance updates as you move the device.
- Area Measurement: Measure two sides (length and width) to automatically calculate the area.
- Volume Measurement: Measure three sides (length, width, and height) to automatically calculate the volume.
- Pythagorean Measurement (Pythagoras-1 & Pythagoras-2): Used for indirect measurements where direct measurement is not possible. Follow the on-screen prompts to take the required measurements (e.g., hypotenuse and one leg).
- Angle Measurement: Utilizes the visual aligning beam for precise angle detection.
- Addition & Subtraction: Allows for adding or subtracting measurements.

7. Maintenance
Proper care and maintenance will extend the life of your ATuMan LS6.
- Cleaning: Use a soft, dry cloth to clean the device. Do not use abrasive cleaners or solvents. For the lens, use a lens cleaning cloth.
- Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, ensure the battery is partially charged (around 50%) and recharge every few months to prevent deep discharge.
- Avoid Impact: While durable, avoid dropping the device or subjecting it to strong impacts.
8. Troubleshooting
If you encounter issues with your ATuMan LS6, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery. | Charge the device using the USB Type-C cable. |
| Display is difficult to read outdoors. | High ambient light. | The TFT color display may be less visible in direct bright sunlight. Try to shade the screen or use in less direct light. |
| Inaccurate measurements. | Obstruction in laser path, unstable surface, or incorrect measurement mode. | Ensure a clear path for the laser. Measure from a stable surface. Verify you are in the correct measurement mode for the task. |
| Difficulty changing settings (e.g., units). | Unfamiliarity with button combinations. | Refer to the detailed instructions in the full printed user manual for specific button sequences for settings adjustments. Practice the button presses. |
| Laser dot not visible at long distances. | Environmental factors (bright light) or target surface. | In very bright conditions or on non-reflective surfaces, the laser dot may be hard to see. Consider using a target plate or measuring at closer distances if possible. For very long distances, a tripod may help stabilize the device. |
If the problem persists after trying these solutions, please contact ATuMan customer support.
