2.4 Reference Point Setting
The L387 allows you to set the measurement reference point from either the front or the rear of the device. Press the reference point button (often indicated by an icon showing the device's base or top) to toggle between these options. The current reference point is indicated on the display.
3. Operating Instructions
3.1 Single Distance Measurement
- Point the laser at the target.
- Press the MEAS button once. The measured distance will appear on the display.
3.2 Continuous Measurement (Tracking)
Press and hold the MEAS button. The device will continuously measure the distance as you move it, displaying the current, minimum, and maximum values. Press MEAS again to stop.
3.3 Area Measurement
- Press the mode button (often indicated by a square icon) until the area measurement mode is selected.
- Measure the length by pressing MEAS.
- Measure the width by pressing MEAS again. The device will automatically calculate and display the area.
3.4 Volume Measurement
- Press the mode button until the volume measurement mode is selected (often indicated by a cube icon).
- Measure length, width, and height sequentially by pressing MEAS after each measurement. The device will calculate and display the volume.
3.5 Pythagorean Measurement (Indirect Height)
This mode allows for indirect height measurements using the Pythagorean theorem. Follow the on-screen prompts to measure the hypotenuse and one leg of a right-angled triangle. The device will calculate the unknown leg (height).

4. Maintenance
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Ensure the laser lens and display are kept clean for accurate readings.
- Storage: Store the device in a dry, dust-free environment, away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery life, charge the device regularly and avoid complete discharge. If storing for extended periods, charge the battery to approximately 50% every few months.
5. Troubleshooting
- Inaccurate Readings:
- Ensure the laser lens is clean.
- Verify the correct reference point is selected (front or rear).
- Check for obstructions in the laser path.
- Ensure the target surface is reflective enough for the laser.
- Device Not Powering On:
- Ensure the battery is charged. Connect to a USB-C charger and wait a few minutes before attempting to power on again.
- Press and hold the MEAS button firmly.
- Unit Defaults to Millimeters:
Some devices may reset to a default unit (e.g., millimeters) after being powered off. To change the unit, press and hold the UNIT button after powering on the device to cycle through available units until your preferred unit is displayed.
- Laser Not Visible:
- In bright ambient light or outdoors, the green laser may be less visible. The L387's green laser is designed to be 4X brighter than standard red lasers for improved visibility.
- Ensure the device is powered on and the laser is activated.
