Mitutoyo SURFTEST SJ-410 - Perform Adjustment for Calibration and Measurement; Perform the Vertical Positioning

4.2 Perform Adjustment for Calibration and
Measurement
To install the SJ-410 after setting up a specimen or workpiece for calibration and
measurement, it is necessary to perform "vertical positioning (adjust the height of the
drive/detector unit)", "horizontal positioning (adjust the measurement starting position)",
and "leveling (adjust the tilt of the drive/detector unit)". For these adjustments, the
height/tilt adjustment unit and simple column stand (optional accessories), etc., are
required.
