The device is not rechargeable. Always use fresh AAA batteries for optimal performance.

6. Operating Instructions

6.1 Basic Measurement (Single Distance)

1. Power On: Short press the Power/Measurement button (red dot on the front).
2. Set Reference Point: Long press the Reference Key on the side to toggle between front-edge or rear-edge measurement reference. The display will show an icon indicating the current reference point.
3. Select Unit: Long press the Unit Key on the side to cycle through measurement units (meters, feet, inches).
4. Aim: Point the device's laser at the target surface.
5. Measure: Short press the Power/Measurement button again to emit the laser and take a measurement. The result will be displayed instantly.
6. Power Off: Long press the Power/Measurement button to turn off the device. The device will also auto-power off after 180 seconds of inactivity.

6.2 Changing Measurement Modes

The device offers 9 measurement modes. To switch between modes, short press the Reference Key (or a dedicated mode button if present, refer to display icons for guidance). The display will show an icon representing the active mode.

7. Measurement Modes Explained

The ATuMan LSA offers the following measurement functions:

1. Single/Continuous Measurement

   Single Measurement: Measures the distance from the device to a single target point. Press the measurement button once to activate the laser, then again to take the reading.

   Continuous Measurement (Tracking): Allows for dynamic measurement as you move the device. The display updates in real-time, showing the current distance. Useful for finding minimum/maximum distances or scanning an area.

2. Area Measurement

   Measures the area of a rectangular space. Take two consecutive measurements (length and width), and the device will automatically calculate and display the area.

   

   Figure 7: Diagram for calculating area.

3. Volume Measurement

   Measures the volume of a cubic space. Take three consecutive measurements (length, width, and height), and the device will automatically calculate and display the volume.

   

   Figure 8: Example of volume measurement in a room.

4. Pythagorean Measurement

   Uses the Pythagorean theorem to calculate indirect distances (e.g., height of a wall) by measuring two or three sides of a right-angled triangle. Follow the on-screen prompts for the required measurements.

5. Real-time Angle Measurement

   Displays the device's current angle in real-time, providing rapid data feedback. This allows for precise angle monitoring without lag or error.

   

   Figure 10: Diagram for real-time angle measurement.

6. Maximum/Minimum Value Measurement

   In continuous measurement mode, this function records and displays the maximum and minimum distances measured during a sweep. Useful for finding the longest or shortest point in a range.

7. Accumulated/Accumulated Subtraction

   Allows you to add or subtract multiple measurements. Take a measurement, then select the addition or subtraction function, and take another measurement. The device will display the cumulative result.

8. Front/Back Reference

   This function allows you to choose whether the measurement starts from the front edge or the rear edge of the device. Long press the Reference Key to toggle this setting.

8. User Tips

• Optimal Accuracy: For the most accurate readings, especially over long distances or in bright conditions, use a target reflector.
• Stable Placement: Ensure the device is placed on a stable surface or held steadily to prevent movement during measurement, which can affect accuracy.
• Environmental Factors: Be aware that extreme temperatures, strong sunlight, or highly reflective/non-reflective surfaces can impact measurement accuracy.
• Battery Life: Replace batteries promptly when the low battery indicator appears to maintain consistent performance.
• Unit Conversion: Familiarize yourself with the unit conversion function to quickly switch between meters, feet, and inches as needed for different projects.

9. Troubleshooting

9.1 Device Not Turning On

• Check if the batteries are inserted correctly with the right polarity.
• Ensure the batteries are not depleted. Replace with fresh AAA batteries if necessary.
• Press and hold the Power/Measurement button for a few seconds to ensure it's not just a short press.

9.2 Inaccurate Readings

• Environmental Conditions: Harsh environments (excessive sunlight, significant temperature fluctuations) can cause errors. Try to measure in more stable conditions or use a target reflector.
• Target Surface: Surfaces with weak reflectivity (e.g., dark, porous materials) or highly reflective surfaces (e.g., mirrors) can affect accuracy. Use a target reflector on such surfaces.
• Device Stability: Ensure the device is held steady and the laser beam is aimed precisely at the target. Any movement during measurement can lead to discrepancies.
• Low Battery: A low battery can impact performance and accuracy. Replace batteries if the low battery indicator is on.
• Reference Point: Verify that the correct measurement reference point (front or rear edge) is selected for your task.

9.3 Display Issues

• If the display is dim or flickering, replace the batteries.
• If the display shows an error code, refer to the specific error code in a more detailed product manual if available, or try restarting the device.

10. Maintenance

• Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the laser lens is clean and free of dust or debris for accurate measurements.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
• Handling: Handle the device with care to avoid drops or impacts that could damage internal components.
