Magnetic attachment: magnetically adheres to the measuring surface and can be affixed to the workpiece being measured for secure, hands setup and stable readings Data lock: locks the measurement data for easy reading and reliable documentation Angle and slope conversion: provides quick reference to standard angles and slopes, streamlining setup and verification Relative and absolute measurement conversion: enables switching between differential (relative) and originbased (absolute) measurements for flexible use Use scenarios Machining and fixture setup: attach to the workpiece or measurement surface to quickly verify perpendicularity, levelness, and angular tolerance without repositioning Assembly and quality control: measure height differences or incline between parts in a fixture, ensuring consistency across components Carpentry and fabrication: check slopes and angles when installing supports, ramps, stairs, or other inclined elements for accurate alignment
