6 CALIBRATION
In this chapter how to perform calibration is described.
The process of calibration involves the measurement of a reference workpiece (precision
roughness specimen) and the adjustment of the difference (gain adjustment), when there
is one between the measured value of the SJ-210 and the reference value (precision
roughness specimen).
Depending on the usage of the SJ-210, calibration should be performed periodically. In
addition, when the instrument is used for the first time or when the detector has been
attached or detached, calibration is necessary.
Without properly calibrating the instrument, correct measurements can not be obtained.
When the drive unit has been changed, first change the drive unit settings. For more
information, refer to 10.5, “Calibrating Drive Unit Speed and Settings”.
