Magnetic bottom base for secure attachment to metal surfaces and measuring tools The device features a bottom magnet that allows secure attachment to the measuring instrument and to the metal workpiece, enabling stable placement during measurement. Relative and absolute measurement conversion Switch between relative measurement and absolute measurement to suit different setup and reference tasks, improving versatility in everyday use. Data lock for easy reading Data lock keeps readings fixed, making it easier to read, record, and transfer measurements without accidental changes. Angle and slope conversion Provides angle and slope conversion capabilities, expanding the range of measurements you can perform on angles, inclines, and slopes. Key benefits Quick mounting on metal surfaces reduces setup time and effort. Flexible measurement modes (relative and absolute) support a variety of workflows. Stable readings with data lock minimize transcription errors and misreadings. Expanded functionality with angle and slope conversions for comprehensive alignment and inspection tasks. Use scenarios Machining setup and alignment: use the device to quickly align drill presses or milling setups by locking in a reference angle and verifying perpendicularity against the workpiece. Fixture alignment and verification: assist in assembling fixtures or weldments by accurately transferring and locking in angular references. Pipe, duct, and ramp installations: check and confirm slopes and angles to ensure proper installation and drainage or flow characteristics.
