While the UI is clunky (function keys and a monochrome LCD), the mechanical accuracy of the SV-400 is still excellent. The inductive pickup stylus is analog and highly linear. Unless you need nanotechnology (1nm Ra), this machine is perfectly viable for ISO 4287 compliance.
Provides a vibration-dampening foundation for stable, sub-micron measurements.
The diamond stylus tip and safety arm mechanism are highly sensitive. Never touch the stylus tip with bare fingers. mitutoyo surftest sv400 user manual full
Mount the reference standard on the stage. Align it perfectly with the path of the stylus.
: Equipped with a wide-range detector offering resolution as fine as 0.000125µm on the 8µm range. Standards Compliance : Evaluates up to 36 roughness parameters While the UI is clunky (function keys and

To maintain high accuracy, regular calibration using a certified Mitutoyo precision roughness specimen (reference specimen) is mandatory. Mount the reference standard on the stage
Without the manual, users often search forums for fixes. Here are three issues the manual resolves directly:
Secure the workpiece on the granite base. Use V-blocks, vises, or clamps if the part is irregular.
Cause: Dirt on the workpiece, external floor vibrations, or a loose detector arm.
: Connect the linear drive unit to the dedicated drive port on the rear of the processing console via the shielded Mitutoyo signal cable. Ensure all thumb screws are finger-tightened to prevent signal modulation. 3. Stylus Handling and Maintenance
