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:
methods. Simply enter the value of your precision specimen to recalibrate the detector sensitivity. Data Management
Use the joystick or drive controls to position the detector over the workpiece.
The diamond tip is highly delicate. Periodically inspect the tip visually with a magnifying tool to ensure it is not chipped or coated in debris. Common Troubleshooting
I can describe how to use ISO/JIS parameters (Ra, Rz, Rq, etc.), traverse units, stylus calibration, and data output via RS-232C or printer. mitutoyo surftest sv400 user manual full
The Mitutoyo Surftest SV400 user manual highlights several key features and functions of the device, including:
A 800μ m range detector with a high resolution of 0.000125μ m (at the 8μ m range).
Inspect cables for wear; clean the drive unit guide paths with a dry lint-free cloth.
Based on the manual's specifications table: The SV-400 series is distinguished by its capability,
Clean the diamond tip with a soft brush dipped in isopropyl alcohol. Never wipe the stylus with hard materials.
Click . Ensure no ambient vibration or noise occurs during the traverse. View the generated profile display. 6. Analysis and Data Management
Press the "Start" button. The detector will traverse the surface, and the screen will display the profile and calculated values. 3.3 Data Output
Select the Digital Gaussian filter (ISO 11562) for standard applications, or the older 2RC filter for legacy project tracking. Primary Measurement Parameters Racap R sub a Data Management Use the joystick or drive controls
A: As mentioned earlier, these filters are critical for proper measurement. The user manual explicitly defines that these controls set the cutoff wavelength for the roughness filter. "Filter 1" is likely the standard filter (Gaussian), while "Filter 2" might be a different type or a 2CR filter (an older standard). In the SV-400's generation, these physical switches were the primary way to select the measurement standard (e.g., JIS 1982, JIS 1994, ISO 1997).
Power down the controller, check all RS-232C/USB connections, restart, and check Windows Device Manager. External vibrations or a loose workpiece setup.
