4. Operating Instructions
4.1 Button Functions and Display Overview

- ON/OFF Button / Laser Switch: Press to turn the device on/off. Long press to activate/deactivate the laser.
- HOLD/Tilt% Button: Press to hold the current measurement. Long press to switch between angle (°) and tilt percentage (%).
- ZERO Button: Press to set the current position as 0° for relative measurements.
- Display: Shows angle, battery level, tilt symbol, laser indicator, and data hold status.
4.2 Absolute and Relative Angle Measurement
The device supports two primary measurement modes:
- Absolute Angle Measurement: Measures the angle relative to a true horizontal surface.
- Relative Angle Measurement: Allows you to set any surface as a 0° reference point to measure the angle of another surface relative to it.

4.3 Performing Measurements
- Power On: Press the ON/OFF button to turn on the device.
- Absolute Measurement: Place the device on the surface you wish to measure. The display will show the angle relative to horizontal.
- Relative Measurement (Zeroing): Place the device on your reference surface. Press the ZERO button. The display will show 0.00°. Now, move the device to the target surface, and the display will show the angle relative to your set reference.
- Hold Function: Press the HOLD button to freeze the current reading on the display. Press again to release.
- Laser Function: Long press the ON/OFF button to activate the dual lasers for marking or alignment. Long press again to turn off.

4.4 Applications
The Digital Angle Finder is suitable for a wide range of tasks:
- Setting saw blade angles on table saws or miter saws.
- Measuring and verifying angles in woodworking projects.
- Leveling surfaces and checking plumb.
- Assisting with hanging pictures and decorations using the dual lasers for alignment.
- Checking vehicle alignment or component angles.
