5. Operating Instructions

5.1. Basic Usage

You can use the digital spirit level as a regular spirit level using the vertical spirit bubble (1) or the horizontal spirit bubble (2). Or use the device as a precise digital spirit level as follows:

1. Shortly press the On/Off key (3) to switch on the digital spirit level.
2. The blue display background light shines for a few seconds. Hold the digital spirit level to the object to be measured and read the currently measured angle on the display (4).
3. If you tilt the digital spirit level at an angle > 90°, the display automatically flips over by 180° for better readability.

5.2. Hold and Backlight Function

1. Press the Hold/Light key (5) to freeze the currently measured value on the display. The background light shines. Press the Hold/Light key one more time to return and show the currently measured values.
2. Press and hold the Hold/Light key (5) for 3 seconds to switch on or off the display background light.

5.3. Absolute (ABS) and Relative (INC) Measurement

1. Shortly press the On/Off key (3) to toggle between displaying the absolute angle (display shows ABS) and displaying the relative angle/the deviation of the angle (display shows INC).
2. When switching to the INC mode, the device resets the display to zero degrees. The following measurement readings refer to this zero point.

5.4. Power Off

1. Press and hold the On/Off key for 3 seconds to switch off the digital spirit level.
2. If you do not operate the device for approx. 5 minutes, the device switches off automatically.

5.5. Magnetic Base

The GVDA Digital Magnetic Level features a strong magnetic base, allowing it to securely attach to metallic surfaces for hands-free operation and accurate measurements.

6. Calibration

The digital spirit level has been calibrated in the factory for maximum accuracy. If necessary, the spirit level can be re-calibrated.

1. Switch off the digital spirit level. Place it on a flat and level surface.
2. Press and hold the Hold/Light key (5). Then additionally press the On/Off key (3). The number "-1-" is flashing on the display.
3. Press the On/Off key (3) once more. The number "-2-" is flashing on the display.
4. 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.

7. User Tips

• The display automatically rotates when you turn the level upside down, enhancing readability in various orientations.
• Utilize the backlight feature for improved visibility in dimly lit environments.
• For critical measurements, always perform a calibration check as described in Section 6 to ensure optimal accuracy.

8. Maintenance and Cleaning

8.1. Cleaning

• Clean the digital spirit level with a smooth and dry linen cloth. If necessary, moisten it slightly.
• Do not use any solvents, detergents, sharp-edged objects, and the like for cleaning.

8.2. Storing
