Display Interface

The display shows measurement results, battery status, measurement mode, and real-time angle information.

5. Setup and Charging

Charging the Device

The DUKA LSB Laser Rangefinder is equipped with a built-in 290mAh rechargeable lithium battery and a Type-C flash charging interface. Before first use, fully charge the device.

1. Connect the provided USB Type-C cable to the charging port on the device.
2. Connect the other end of the cable to a standard USB power adapter (not included) or a computer USB port.
3. The battery indicator on the display will show charging status.
4. A full charge can last for approximately 4500 measurements.

6. Operating Modes

The DUKA LSB offers 10 professional measurement modes for various applications. Use the mode button to cycle through the available options.

Measurement Modes:

1. Single Measurement: Measures the direct distance between two points.
2. Continuous Measurement: Provides real-time distance updates as the device moves, useful for tracking changes or finding minimum/maximum distances.
3. Area Measurement: Calculates the area of a rectangular space by taking two measurements (length and width).
4. Volume Measurement: Calculates the volume of a space by taking three measurements (length, width, and height).
5. Pythagorean Triple (Indirect Measurement): Calculates an unknown side of a right-angled triangle using two known sides.
6. Second Pythagorean Theorem (Indirect Measurement): Calculates an unknown height or distance using three measurements in more complex scenarios.
7. Add in a Straight Line: Adds consecutive linear measurements.
8. Subtraction of Straight Lines: Subtracts consecutive linear measurements.
9. Delay Measurement: Initiates a measurement after a 5-second countdown, allowing for stable data capture in single-person operations or fixed positions.
10. Real-time Angle: Displays the current angle of the device relative to a horizontal plane, useful for picture hanging or complex angle assessments.

7. Taking Measurements

To take a measurement, ensure the device is powered on. Select the desired measurement mode using the mode button. Aim the laser at the target and press the measurement button. The result will be displayed on the screen.

General Measurement Tips:

• For best accuracy, ensure the device is stable and the laser beam is perpendicular to the target surface.
• The green laser offers superior visibility outdoors and in bright conditions compared to red lasers.
• The device can measure distances from 0.03m to 50m with an accuracy of ±(2mm+D*(1/10000)).

8. Maintenance

• Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the laser lens is clean for accurate measurements.
• Storage: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
• Battery Care: Recharge the battery regularly, even if the device is not in frequent use, to maintain battery health.
• Avoid Impact: The aluminum alloy body provides durability, but avoid dropping or subjecting the device to strong impacts.

9. Troubleshooting

Device does not turn on:

Ensure the battery is charged. Connect the device to a power source using the USB-C cable and try again.

Inaccurate measurements:

Check if the laser lens is clean. Ensure the target surface is flat and reflective enough. Avoid measuring through transparent materials like glass. Strong light conditions might affect visibility, but the green laser is designed to mitigate this.

Laser beam is not visible:

In very bright outdoor conditions, the laser spot might be difficult to see with the naked eye, even with a green laser. Try to shade the target area or use a laser target plate if available.
