NOTE
• If the SJ-410 needs to be calibrated with a standard other than the supplied precision
roughness specimen, the default calibration conditions must be modified for the
roughness specimen to be used. For information about changing the calibration
condition settings, refer to "6.4 Setting Calibration Conditions" (page 6-11).
