5. Operación
5.1 Medición básica de distancias
- Encienda el dispositivo presionando el botón LEER botón.
- Presione el LEER button again to activate the laser beam. A red laser dot will appear.
- Aim the laser dot at the target point from which you want to measure the distance.
- Presione el LEER button once more. The measured distance will be displayed on the screen.
5.2 Modos de medición
The LDM-50S offers several measurement modes. Press the FUNC button (often labeled with a square/triangle icon) to cycle through the available modes:
- Medida individual: Mide la distancia entre dos puntos.
- Medición continua (seguimiento): Proporciona actualizaciones de distancia en tiempo real a medida que mueve el dispositivo.
- Medida de área: Measures length and width to calculate the area of a surface.
- Medida de volumen: Measures length, width, and height to calculate the volume of a space.
- Pythagoras Mode: Calculates indirect measurements (e.g., height or diagonal) using the Pythagorean theorem. Follow the on-screen prompts to take the required measurements.
