Data lock for easy reading: freezes the current measurement on the display so you can document results without rechecking the reading. Relative and absolute measurement conversion: quickly switch between relative increments and absolute positions to support setup, reference checks, and traceability in inspection. Angle and slope conversion: measures angles and slopes and provides direct conversions to the required references, simplifying layout, fixturing, and verification tasks. Magnetic base and attachment: magnetically adheres to ferrous surfaces and can be attached to the workpiece being measured for hands operation and flexible mounting during measurement. Compatibility and readability: designed for use with standard measuring setups and fixtures, with a clear, easytoread display for reliable performance in typical workshop environments. Use scenarios Machining setup and zeroing: attach the device to a ferrous work surface, set a zero or reference point, and use the data lock to capture and document the baseline measurement for repeatable setups. Angle and slope verification in fabrication: mount on a fixture or part to measure angles and slopes, then convert to the required reference values for layout or quality checks. Onthefloor QC documentation: during inspection, lock readings to record measurements accurately for QC reports and traceability, while keeping hands to handle the workpiece.
