6. Instruccions de funcionament
6.1 Acabatview de Controls

Imatge: Un primer pla view of the NOYAFA NF-271, with labels pointing to each button and its primary function: Measure, Menu, Add, Subtract, Benchmark & Unit Switch, Record Query & Setting, and Power & Clear.
- Botó MEAS: Initiates measurement, confirms selection.
- Botó de menú: Accesses measurement modes (Area, Volume, Pythagorean).
- Botó +: Adds measurements.
- - Botó: Subtracts measurements.
- Benchmark & Unit Switch Button: Changes measurement reference point (front/rear) and units (m/ft/in).
- Record Query & Setting Button: Views historical measurements and accesses settings.
- Power & Clear Button: Powers on/off, clears current measurement.
6.2 Mesura bàsica de distàncies
- Premeu el botó Potència i clar botó per encendre el dispositiu.
- Apunteu el làser al punt objectiu.
- Premeu el botó MEAS botó. La distància mesurada es mostrarà a la pantalla.
6.3 Mesura de l'àrea
Per mesurar l'àrea d'una superfície:
- Premeu el botó Menú button until the Area icon (a square) appears on the display.
- Premeu MEAS per mesurar el primer costat (per exemple, la longitud).
- Premeu MEAS de nou per mesurar el segon costat (per exemple, l'amplada).
- El dispositiu calcularà i mostrarà l'àrea automàticament.

6.4 Mesura del volum
Per mesurar el volum d'un espai:
- Premeu el botó Menú button until the Volume icon (a cube) appears on the display.
- Premeu MEAS per mesurar la longitud.
- Premeu MEAS de nou per mesurar l'amplada.
- Premeu MEAS una tercera vegada per mesurar l'alçada.
- El dispositiu calcularà i mostrarà el volum automàticament.

6.5 Mesura pitagòrica
The Pythagorean mode allows indirect measurement of heights or distances using the Pythagorean theorem.
6.5.1 Direct Pythagorean Measurement (Single Pythagorean)
Used to calculate the height of an object when you can measure the hypotenuse and one leg of a right triangle.
- Premeu el botó Menú button until the single Pythagorean icon appears (a right triangle with the hypotenuse highlighted).
- Measure the hypotenuse (distance from the device to the top of the object).
- Measure the base (horizontal distance from the device to the bottom of the object).
- El dispositiu calcularà i mostrarà l'alçada.

6.5.2 Secondary Pythagorean Measurement
Used for more complex height calculations, often when the base cannot be directly measured from the device's position.
- Premeu el botó Menú button until the secondary Pythagorean icon appears (two right triangles sharing a common leg).
- Measure the first hypotenuse (distance from device to top of object).
- Measure the second hypotenuse (distance from device to bottom of object).
- The device will calculate and display the height difference.
6.6 Unit Switching and Benchmark
- Premeu el botó Benchmark & Unit Switch button to cycle through measurement units (meters, feet, inches).
- Mantingueu el Benchmark & Unit Switch button to change the measurement reference point (from the front or rear of the device).
6.7 Registre històric
The device stores recent measurements. Press the Record Query & Setting botó per view lectures prèvies.
