2. Safety Notes
- This manual is an integral part of the product. Please ensure it is passed on with the unit if transferred to a third party.
- Dispose of packaging materials carefully. Plastic bags can be a hazard to children. This digital spirit level is not a toy; keep it out of reach of children.
- If the unit will not be used for an extended period, remove the batteries to prevent leakage.
- Do not disassemble, burn, or short-circuit batteries. Do not attempt to recharge non-rechargeable batteries.
- Do not attempt to disassemble or repair the unit yourself. It contains no user-serviceable parts. For questions or problems, contact customer support.
- Batteries and rechargeable batteries must be disposed of according to local regulations, not with household garbage.
3. Setup
Inserting / Replacing the Battery
The battery compartment (6) is located on the rear side of the digital spirit level.
- Depress the latch of the battery compartment lid and open the compartment.
- Insert 2 new 1.5V AAA batteries (not included) into the battery compartment. Ensure correct polarity as indicated inside the compartment.
- Close the battery compartment lid securely.

4. Operation
Basic Usage
You can use the digital spirit level as a regular spirit level by observing the vertical spirit bubble (1) or the horizontal spirit bubble (2). For precise digital measurements, follow these steps:
- Shortly press the On/Off key (3) to switch on the digital spirit level.
- The blue display background light will illuminate for a few seconds. Hold the digital spirit level against the object to be measured and read the currently measured angle on the display (4).
- If you tilt the digital spirit level at an angle greater than 90°, the display will automatically flip over by 180° for better readability.
Hold and Backlight Function
- Hold Function: Shortly press the Hold/Light key (5) to freeze the currently measured value on the display. The backlight will also illuminate. Press the key again to release the hold and show current values.
- Backlight Control: Press and hold the Hold/Light key (5) for 3 seconds to switch the display background light on or off.
Absolute and Relative Angle Measurement (INC/ABS)
- Shortly press the On/Off key (3) to toggle between displaying the absolute angle (display shows ABS) and displaying the relative angle/deviation (display shows INC).
- When switching to the INC mode, the device resets the display to zero degrees, allowing you to measure relative angles from that new zero point.
Automatic Shut-off
- To manually switch off the digital spirit level, press and hold the On/Off key (3) for 3 seconds.
- The device will automatically switch off after approximately 5 minutes of inactivity to conserve battery life.
Notes on Display Indicators
- The deviation (7) in mm/m of the currently measured angle is displayed when an angle is ≤ 5.7° (max. 100 mm/m).
- A small arrow icon (8) will appear, indicating if the device is measuring ascending (arrow up) or descending (arrow down) angles.
Calibration
The digital spirit level is factory calibrated for maximum accuracy. If recalibration is necessary, follow these steps:
- Switch off the digital spirit level. Place it on a flat and level surface.
- Press and hold the Hold/Light key (5). Then, additionally press the On/Off key (3). The number "-1-" will flash on the display.
- Press the On/Off key (3) once more. The number "-2-" will flash on the display.
- Horizontally flip over the digital spirit level by 180°. Then press the On/Off key (3) one more time to finish the calibration process.
Note: Ensure the digital spirit level is kept absolutely steady during calibration.
5. Maintenance
Cleaning and Storing
- Clean the digital spirit level with a smooth and dry linen cloth. If necessary, moisten the cloth slightly.
- Do not use any solvents, detergents, sharp-edged objects, or similar abrasive materials for cleaning.
- Store the unit in a dry place that is protected from dust and dirt.
- Store it out of reach of children.
6. Troubleshooting
- Display is dim or unreadable: This usually indicates low battery power. Replace the AAA batteries with new ones, ensuring correct polarity.
- Inaccurate readings: Ensure the surface you are measuring is clean and free of debris. Perform a calibration as described in the Operation section (Section 4).
- Device does not turn on: Check if batteries are inserted correctly and have sufficient charge. If the issue persists, try new batteries.
- Display shows error codes: Refer to the official PDF manual for specific error code interpretations.
