The document provides instructions for setting up and using a 3-axis digital display product, including connecting the HY-TB3DV-M driver board to a power supply and digital interface, setting the origin point and pulse values for each axis, and using the display to show real-time coordinate values or reset values to zero. Steps are outlined for entering the setup mode, assigning pulse values to each axis for 0.1mm movements, and exiting setup mode once values are set.
