The SV-400 series is distinguished by its capability, which allows it to measure waviness and finely stepped features that standard skidded testers cannot accurately detect. Detector Range: Up to (standard) with a resolution down to Traverse Length: Typically (SJ-401) or Straightness Accuracy:
The SV-400 calculates multiple surface profile characteristics simultaneously: Definition Practical Application Arithmetical mean roughness General quality checks across all manufacturing industries. Maximum height of the profile Identifies isolated deep scratches or high peaks. Root mean square roughness Used in optical and high-precision applications. Rsmcap R s m Mean width of profile elements Evaluates textured surfaces or regular machining marks. Maintenance and Troubleshooting Routine Maintenance
Preventive maintenance is covered in the final chapters of the user manual. To extend the life of your $15,000+ instrument: mitutoyo surftest sv400 user manual full
The Mitutoyo Surftest SV-400 is a high-precision, surface roughness measuring instrument designed for laboratory and shop-floor quality control. This comprehensive guide serves as an operational reference manual, outlining setup procedures, calibration steps, measurement modes, and system maintenance. System Overview and Component Layout
: A built-in safety device in the Z1-axis detector automatically stops movement to prevent damage upon contact with a workpiece or fixture. The SV-400 series is distinguished by its capability,

Place the unit on a heavy, vibration-free surface (ideally a granite surface plate). Avoid areas with direct sunlight, high humidity, or strong magnetic fields.
Use the joystick or drive controls to position the detector over the workpiece.
