Mitutoyo Surftest SV-400 is a high-precision profilometer designed for both laboratory and rigorous production line environments. It is frequently categorized within the SJ-400 Series
of portable surface roughness testers, which share a core set of features focused on skidless measurement and high-resolution data analysis. Wolverine Machine Core Measurement Capabilities Dual Measurement Modes : Switchable between
measurement. Skidless mode allows for the evaluation of waviness and fine contour features that traditional skidded testers cannot detect accurately. High Resolution : Offers a detector resolution as fine as 0.000125µm (at the 8µm range) and a measuring range up to Surface Compensation
: Features specific R-surface compensation and curved surface functions, making it highly effective for measuring cylinder surface roughness.

Conclusion
The Mitutoyo Surftest SV-400 (often part of the wider SJ-400 series family in modern documentation) is a high-precision, portable surface roughness tester designed for both laboratory and production line use. This guide provides a detailed operational overview based on official Mitutoyo documentation. 1. Initial Setup & Installation
Environment: Place the unit on a stable surface free from dust, dirt, vibration, and extreme humidity.
Safety: Turn the power off before connecting any cables or performing maintenance to avoid electric shock or malfunctions.
Components: The system typically includes a Control Unit with a touch-panel LCD, a Drive Unit for traverse movement, and a Detector with a diamond stylus tip. 2. Detector Calibration (Auto-Calibration)
Calibration ensures accuracy by adjusting the gain based on a known standard. Place the provided precision specimen under the detector. Navigate to the Auto-Calibration menu on the touch panel.
Enter the calibrated value of the precision specimen as indicated on its certificate.
Initiate the calibration; the system automatically adjusts for Ra calibration or step calibration. 3. Measurement Procedure Surface roughness measurement importance in manufacturing
The SV-400 supports both Skid and Skidless measurement modes.
Step 1: Alignment: Use the D.A.T. (Digital Adjustment Tilting) function to level the drive unit. The screen will prompt you to turn the tilt adjustment knob by a specific amount (e.g., "1.37 turns counter-clockwise") to achieve a level reference plane. Step 2: Configuration: Standard: Select ISO, ANSI, VDA, or JIS standards.
Profile: Choose between Primary profile (P), Roughness profile (R), or Filtered waviness (W). Filter: Set the cutoff length ( λclambda sub c
) and the number of sampling lengths (typically 5) based on your technical drawings.
Step 3: Execution: Position the stylus at the start point using the touch-panel icons. Press the Start button. The drive unit will traverse the surface, and the profile will appear on the LCD. 4. Data Analysis & Recalculation Surftest SJ-400 - Mitutoyo
Most SV-400 units shipped with a 3.5-inch floppy disk drive for data output.
When your SV-400 stops working, open the manual to Table 6-1. Common codes include:
