6. Instruccions de funcionament
6.1. Mesura bàsica de distàncies
- Premeu el botó LLEGIR botó per encendre el dispositiu.
- Apunta el làser a l'objectiu.
- Premeu el botó LLEGIR Premeu el botó de nou per prendre una mesura. La distància es mostrarà a la pantalla.
6.2. Canvi d'unitats de mesura
Premeu llargament el botó U button to cycle through the available measurement units: meters (m), inches (in), feet (ft), and feet+inches (ft+in).

Figure 6.1: Changing units and reference points.
6.3. Changing Reference Point
Premeu breument U button to switch the measurement reference point between the front edge and the rear edge of the device. The current reference point is indicated on the display.
6.4. Mesura contínua
In continuous measurement mode, the device constantly measures and displays the distance as you move it, allowing for dynamic tracking of measurements.
6.5. Mesura de l'àrea
To measure area, the device will prompt you to measure two sides (length and width). It then automatically calculates and displays the area.
6.6. Mesura de volum
For volume measurement, the device will guide you to measure three dimensions (length, width, and height). It then automatically calculates and displays the volume.
6.7. Mesura pitagòrica
The device supports various Pythagorean modes (two-point and three-point) to calculate indirect distances, such as height or diagonal measurements, by measuring other sides of a right-angled triangle.
