4. Impostazione
4.1 Installazione della batteria
The digital level requires batteries for operation. Locate the battery compartment, typically on the side or back of the digital module. Insert the required batteries, ensuring correct polarity (+/-). Close the compartment securely.
Note: The product specifications indicate "Batteries Included? No" and "Batteries Required? No" which may be a data discrepancy. Assume batteries are required and not included.
4.2 Accensione iniziale
Premere il tasto Acceso/Spento button to power on the device. The digital display will illuminate and show the current angle or slope.
5. Istruzioni per l'uso
5.1 Accensione/spegnimento
Premere il tasto Acceso/Spento button to turn the digital level on or off.
5.2 Esecuzione delle misurazioni
Place the measuring surface of the level firmly against the object you wish to measure. The digital display will show the angle in degrees, percentage, or mm/m, depending on the selected unit.

5.3 360° Readout
The level features a 360° readout, meaning the display automatically flips when the level is inverted, ensuring the reading is always upright and easy to read from any orientation.
5.4 Funzione di attesa
Premere il tasto Presa button to freeze the current measurement on the display. This is useful for taking readings in difficult-to-see areas or when you need to record a specific value. Press Presa nuovamente per rilasciare la funzione.
5.5 Selezione delle unità
Use the unit selection button (often labeled with °/%/mm/m or similar icon) to cycle through different measurement units: degrees (°), percentage (%), and millimeters per meter (mm/m).
5.6 Reference Function
IL Riferimento function allows you to set the current position as a new "0" reference point. This is useful for measuring relative angles from a specific surface. To activate, place the level on your desired reference surface and press the Riferimento button. The display will show "0.0" and subsequent measurements will be relative to this new reference.
5.7 Calibrazione
For optimal accuracy, periodic calibration may be required. To calibrate the level:
- Place the level on a flat, stable surface.
- Premere il tasto Calibrare button. Follow the on-screen prompts, which typically involve rotating the level 180 degrees and pressing the button again.
- Refer to the specific calibration sequence indicated on the device's display or a more detailed manual if available.
6. Manutenzione
6.1 Pulizia
Wipe the level with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or housing. Ensure the device is dry before storage.
6.2 Conservazione
Store the digital level in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
