4. Operation
The REVASRI KL02 offers multiple measurement modes to suit various applications. Use the FUNC button to cycle through the modes.
4.1 Basic Distance Measurement
- Ensure the device is in single distance measurement mode (default or select via FUNC).
- Point the laser at the target surface.
- Press the Measurement button once. The measured distance will appear on the screen.
4.2 Continuous Measurement (Min/Max)
- From single distance mode, press and hold the Measurement button for 1 second to enter continuous measurement.
- Move the device slowly. The screen will display real-time maximum, minimum, and current distances.
- Press the Measurement button again to stop.
4.3 Area Measurement

- Press FUNC until the area icon appears.
- Measure the first side (length) by pressing the Measurement button.
- Measure the second side (width) by pressing the Measurement button again.
- The device will automatically calculate and display the area.
4.4 Volume Measurement

- Press FUNC until the volume icon appears.
- Measure length, width, and height sequentially by pressing the Measurement button for each dimension.
- The device will automatically calculate and display the volume.
4.5 Pythagorean Measurement (Indirect Measurement)

The Pythagorean mode allows for indirect measurement of heights or distances when direct measurement is not possible.
- Press FUNC until the desired Pythagorean icon appears (e.g., 2-point or 3-point).
- Follow the on-screen prompts to take the required measurements (e.g., hypotenuse, base).
- The device will calculate and display the unknown dimension.
4.6 Addition and Subtraction
- Perform a measurement.
- Press the +/- button to select addition or subtraction.
- Perform the next measurement. The result will be added to or subtracted from the previous measurement.
4.7 Unit Switching
- Press the Unit button to cycle through available units: meters (m), inches (in), and feet (ft).
4.8 Stakeout Function

The stakeout function allows you to set a predetermined target value. For example, to cut a piece of wood to 1 meter, set the target value to 1m. The device will guide you to the precise point.
5. Data Storage

The REVASRI KL02 can store up to 28 groups of measurement data. To access stored data, press the History/Preset button. Use the arrow buttons (if available, or repeat pressing the history button) to navigate through the stored measurements.

7. Troubleshooting
If you encounter issues with your REVASRI KL02, refer to the following common problems and solutions:
- Problem: Cannot obtain a reading.
Solution: The minimum range is typically 0.05m. Ensure the distance is within the allowed range. Avoid measuring through glass or in very small rooms. Strong light, rain, fog, or heavy dust can also affect laser transmission and measurement accuracy. - Problem: Measurement accuracy seems inconsistent.
Solution: Environmental factors such as strong sunlight, fog, rain, or dust can interfere with the laser. Ensure the target surface is clear and the environment is suitable for laser measurement. - Problem: Device does not turn on.
Solution: Check the battery level. If the battery is low or depleted, charge the device using the provided USB-C cable.
