2.2 Włączanie/wyłączanie
Naciśnij Moc button (usually marked with a power symbol) to turn the device on or off.
3. Działanie
3.1 Pomiar podstawowy
Place the device on the surface you wish to measure. The angle will be displayed on the LCD screen. The display value automatically inverts when the electronic level is upside down for easier reading.

3.2 Tryby pomiaru bezwzględnego i względnego
This digital protractor offers two measurement modes:
- Pomiar kąta bezwzględnego: Used to test if a surface is level (0°) or to verify specific slopes, such as roof pitches or wheel alignment.
- Pomiar kąta względnego: Allows you to measure the angle between two surfaces. Press the ZERO button on a reference surface to set it as 0°, then move the device to the second surface to measure the relative angle.
Naciśnij ZERO button to switch between absolute and relative modes or to zero out the current reading.

3.3 Wybór jednostki
The device can display angle readings in various units:
- Stopnie (°)
- IN/FT (inches per foot)
- mm/M (millimeters per meter)
- Procenttage of slope (%)
Naciśnij TRYB button to cycle through the available measurement units.
3.4 Funkcja wstrzymania
Aby zamrozić aktualny odczyt na wyświetlaczu, naciśnij przycisk TRZYMAĆ button. This is useful for recording measurements in difficult-to-view positions. Press TRZYMAĆ ponownie, aby uwolnić odczyt.
3.5 Backlit LCD and Audio Indicator
The large, bright LCD screen is backlit, allowing for easy reading in various light conditions. The device also features an acoustic signal (beeps) that indicates when the measurement reaches 0° or 90°, providing an audible cue for level or plumb positions.
3.6 V-Groove Magnetic Base
The integrated V-groove magnetic base allows the device to be firmly attached to ferrous metal surfaces. This feature is particularly useful for hands-free operation on pipes, steel construction frames, and during metal fabrication tasks.

4. Konserwacja
4.1 Czyszczenie
Aby wyczyścić urządzenie należy przetrzeć je miękką, damp ściereczką. Nie używaj środków czyszczących ani rozpuszczalników o działaniu ściernym, ponieważ mogą one uszkodzić wyświetlacz lubasing.
4.2 Przechowywanie
When not in use, store the device in a dry, cool place, away from direct sunlight and extreme temperatures. If storing for extended periods, remove the batteries to prevent leakage.
4.3 Stopień ochrony IP65
The eOUTIL Digital Level Angle Finder has an IP65 rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. This makes it suitable for use in challenging environmental conditions, including those with water splashes and dust. However, it is not designed for immersion in water.

5. Rozwiązywanie Problemów
- Urządzenie się nie włącza: Check if the batteries are inserted correctly with the right polarity. Replace batteries if they are depleted.
- Niedokładne odczyty: Ensure the measurement surface is clean and free of debris. If readings are consistently inaccurate, especially when rotated 180 degrees, the device may require calibration. Refer to the manufacturer's specific calibration instructions, which may be provided in a separate document or on their webstrona.
- Wyświetlacz jest przyciemniony lub migocze: Wymień baterie.
- Display shows 'Err' or other error codes: Turn the device off and then on again. If the error persists, contact customer support.
