Basic Operation:
- Power On/Off: Press and hold the power button (usually marked with 'M' or a power symbol) to turn the device on or off.
- Mode Switching: Short press the power button to cycle between different operating modes (Absolute Angle and Relative Angle).
- Laser Activation: The laser line can be activated or deactivated by a dedicated button or a specific press sequence, refer to the device's physical buttons for exact functionality.
Angle Measurement:
- Place the base of the DUKA LI1 on the surface you wish to measure the angle from.
- The dual LED screen will display the current angle relative to the horizontal plane (Absolute Angle mode) or relative to a set reference (Relative Angle mode).
- For relative angle measurement, place the device on the first surface, press the mode button to set it as the 0-degree reference, then move the device to the second surface to measure the angle between them.
Laser Line Projection:
- Activate the laser line function.
- Position the DUKA LI1 to project the laser line onto the desired surface. The laser line can be used for alignment, leveling, or marking.
- The device can project a single-sided laser line, useful for precise alignment over distances up to 10 meters indoors.
