4.3.1 Setting the workpiece and SJ-210
■ Setting the workpiece and SJ-210
When the workpiece surface is larger than the SJ-210, place the SJ-210 on the workpiece.
For surface roughness measurement to be successful, it should be performed on a firm
base that is insulated as well as possible from all sources of vibration. When
measurement is performed being subject to significant vibrations, results may be
unreliable.
TIP
• In cases where the measured surface is smaller than the SJ-210 or where the surface is
curved (cylindrical, etc.), install the SJ-210 using an appropriate optional accessory. For
information about optional accessories, refer to Chapter 14, “INSTALLING THE SJ-210
WITH OPTIONAL ACCESSORIES”.
1 Position the work piece so that the measured surface is level.
2 Place the SJ-210 on the workpiece.
In this operation, support the SJ-210 by reference surfaces A and B on the bottom of
the driving unit, as shown below.
