Value Lock Function for Critical Measurements Capture hardtoreach or unstable measurements and freeze the display reading until you clear it. This helps you document results accurately and work in awkward positions without losing the measurement. MultiFunction Measurement Modes for Versatile Use Switch between absolute angle, relative difference, and slope percentage with the mode button. The unit conversion feature instantly displays results in degrees, percent grade, or meters to meet diverse project requirements. Magnetic Builtin Strong Magnets Builtin magnets securely attach to metal surfaces, allowing stable measurements on pipes, beams, and machinery. This enables hands operation and helps maintain consistent contact with the measured surface. Measurement Lock Function Lock the display to capture hardtoreach or unstable measurements. The reading remains visible until manually cleared, making it ideal for documenting results or working in awkward positions. Use scenarios On a construction site, measure the angle of a support beam and use Value Lock to freeze the reading while you reposition, ensuring an accurate final measurement. While installing piping, attach the device with magnets to a metal pipe to obtain a stable angle or slope reading without constant reattachment. In quality assurance, lock measurements for later recording in reports, especially when measurements are taken from difficulttoaccess locations.
