    2-2. Setting the Length Measurement Parameters Use the “Non-Contact Displacement Sensor Software” to set the length measurement parameters. For details, see the User’s Manual of Non-Contact Displacement Sensor Software. 2-2-1. Setting the pulse resolution The main unit outputs AB phase pulse signals as the length measurement information. The resolution of AB phase pulse can be set.
  • Page 14: Calibration

    2-3. Calibration An absolute length measurement value error may occur depending on the installation state of the main unit or the characteristics of the target measurement object. Calibration allows you to obtain a length measurement value close to your estimate. What are required for calibration - A sample equivalent to the actual length measurement object - A measure to move by already known length...
