3.3 Measurement Modes
The DUKA LSA offers 9 distinct measurement modes:
- Single/Continuous Measurement: For quick, one-time distance measurements or continuous tracking of distance changes.
- Area Measurement: Calculates the area of a surface by measuring two sides.
- Volume Measurement: Calculates the volume of a space by measuring three dimensions (length, width, height).
- Pythagorean Measurement (Indirect Measurement): Uses the Pythagorean theorem to calculate inaccessible distances (e.g., height of a building).
- Real-Time Angle: Displays the current tilt angle of the device.
- Maximum/Minimum Value: In continuous measurement mode, it records and displays the maximum and minimum measured distances.
- Accumulation/Reduction: Adds or subtracts multiple measurements.
- Front/Rear Benchmark: Allows you to choose whether measurements are taken from the front or rear edge of the device.

5. Maintenance
To ensure the longevity and optimal performance of your DUKA LSA Laser Rangefinder, follow these maintenance guidelines:
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the laser lens and display screen are kept clean for accurate readings.
- Storage: Store the device in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent leakage.
- Handling: While the device is designed with a durable ABS body, avoid dropping it or subjecting it to strong impacts.
- Battery Replacement: Replace batteries promptly when the low battery indicator appears on the display.
6. Troubleshooting
If you encounter issues with your DUKA LSA Laser Rangefinder, try the following solutions:
- Device Not Turning On: Check if the batteries are correctly installed and have sufficient charge. Replace with new batteries if necessary.
- Inaccurate Readings: Ensure the laser lens is clean and unobstructed. Make sure the target surface is suitable for laser measurement (highly reflective or transparent surfaces can cause errors). Verify that the correct benchmark (front/rear) is selected.
- Laser Not Emitting: Check battery level. Ensure no obstructions are blocking the laser aperture.
- Display Issues: If the display is dim or flickering, replace the batteries.
For persistent issues not resolved by these steps, please contact customer support.
