4. Mode d'emploi
4.1 Mesure de distance laser
This mode allows for precise distance measurements up to 400ft (120m) with an accuracy of ±1/16 inch.
- Activer: Appuyez sur le Power ON/Measure bouton pour activer le laser.
- Mesure: Aim the laser at the target point and press the Power ON/Measure Appuyez de nouveau sur le bouton pour effectuer la mesure. Le résultat s'affichera à l'écran.

4.2 Green Cross Line Laser Level Mode
The integrated green cross-line laser provides horizontal and vertical lines for leveling and alignment tasks, with a working distance of up to 33ft (10m) and an angle accuracy of ±1°.
- Activer: Appuyez sur le Laser Level Mode button to project the green cross lines.
- Mise à niveau : Place the device on a stable surface. The screen displays angles from -90° to +90° horizontally. If the angle exceeds ±4°, the 'Out' icon will flash, and the laser line will flash rapidly, indicating it is out of level.
- Monture de trépied: For enhanced stability and precise positioning, the device features a 1/4"-20 tripod mount.

4.3 mètre ruban
A traditional 6.5ft (2m) physical tape measure is integrated for short-distance measurements or when a laser is not suitable.
- Usage: Pull out the tape measure from the side of the device. Ensure it retracts smoothly after use.
4.4 Measurement Modes and Functions
The SW-T120 supports various measurement calculations:
- Mesure de distance : Single distance measurement.
- Mesure de surface : Calcule l'aire d'une surface.
- Mesure des volumes : Calcule le volume d'un espace.
- Indirect Height (Pythagoras): Calculates height using two or three measurements.
- Mesure continue : Fournit des mises à jour de distance en temps réel à mesure que l'appareil est déplacé.
- Addition/Soustraction : Allows for adding or subtracting measurements.
