Official instruction manuals and technical documentation for the Mitutoyo Surftest SV-400 (SJ-400 series) are available through the Mitutoyo Europe download center and authorized distributors. The Surftest SJ-400 provides comprehensive, high-accuracy surface roughness analysis, including both skidded and skidless measurement methods. To access the official documentation, visit Mitutoyo Europe.  Surftest SJ-400 - Mitutoyo

Mitutoyo Surftest SV-400 is a high-precision, skidless surface roughness tester designed for laboratory-grade accuracy in a portable or bench-top format. While similar to the popular SJ-400 series

often appears in advanced industrial settings for measuring ultra-fine steps and straightness Wolverine Machine Core Technical Features Measurement Modes : Supports both (using a reference skid for general roughness) and

measurement (relative to the drive unit's internal guide) to accurately capture waviness and stepped features. High Resolution

: 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

(including Ra, Ry, Rz, Rq, and more) conforming to the latest ISO, DIN, ANSI, and JIS standards. Analysis Tools

: Features a "ruler function" for coordinate difference evaluation on the LCD and advanced R-surface compensation for measuring cylindrical workpieces. Operational Guide Summary Calibration Ra auto-calibration method by entering the value of the included precision specimen. mitutoyo surftest sv400 user manual full

function to guide leveling adjustments during skidless measurements.

Fine-positioning for small holes is managed via manual adjustment knobs or an optional joystick on the control unit. Data Management

Results can be printed via the built-in high-speed thermal printer in various formats, including BAC (Bearing Area Curve) and ADC (Amplitude Distribution Curve). Data can be transferred to a PC using an RS-232C cable or stored on an optional memory card for use with Mitutoyo FORMTRACEPAK software ミツトヨ Maintenance Tips

: Gently wipe the unit with a soft, lint-free cloth. For stubborn dirt, use a cloth soaked in neutral detergent; avoid organic solvents like thinner or benzine. Stylus Protection : The diamond tip is extremely delicate. Always use the probe retraction function

or remove the probe when the device is not in use to prevent accidental damage. Why is the SV-400 Manual so hard to find

: Avoid using the device in environments with volatile gases, strong electric fields, or corrosive air. Surftest SJ-400 - Mitutoyo

REPORT: Mitutoyo Surftest SV-400 User Manual Analysis

Date: October 26, 2023 Subject: Comprehensive Review and Operational Summary of the Mitutoyo Surftest SV-400 User Manual Model Covered: Surftest SV-400 (Series 178)

Why is the SV-400 Manual so hard to find?

Mitutoyo has reorganized their support portal several times over the last two decades. The SV-400 uses a specific controller (often the SA-941 or similar) and a dedicated amplifier. General surface roughness guides won't help you here.

Pro Tip: When searching, don't just search for "SV-400." Try searching for the Specific Kit Model Number. The SV-400 was often sold as a system including:

• Surftest SV-400 (Measuring unit)
• Surftest SA-941 (Drive unit/Controller)
• Surftest 211-621 (Detector)

1. Executive Summary

This report provides a structural and functional analysis of the official user manual for the Mitutoyo Surftest SV-400. The SV-400 is a advanced surface roughness measuring instrument designed for high-precision inspection of surface texture parameters. The manual serves as a critical document for quality assurance personnel, metrologists, and maintenance staff. It covers safety protocols, operational procedures, parameter definitions, and troubleshooting. This report summarizes the key sections of the manual to serve as a quick-reference guide for users. set the traverse length

Why You Need the Full User Manual for the SV-400

The Surftest SV-400 is a sophisticated instrument featuring a traversing unit, a detector (pick-up), a drive unit, and a data processing unit. Unlike basic handheld testers, the SV-400 allows for contour analysis, roughness measurement, and waviness assessment.

Searching for a "quick start guide" online often leaves users with fragmented information. The full user manual provides:

1. Safety Protocols: The SV-400 uses AC power and has moving mechanical parts. The manual outlines critical safety warnings to prevent electrical shock or mechanical damage.
2. Detailed Assembly Instructions: The system consists of a column, drive unit, and controller. Improper assembly leads to measurement errors.
3. Parameter Definitions (JIS, ISO, ANSI, VDA): Surface roughness is defined by parameters like Ra, Rz, Ry, and Sm. The manual explains which standard applies to your industry.
4. Calibration Procedures: Without official calibration steps, your data is invalid for ISO certification.
5. Error Code Dictionary: When the machine displays "Err-01" or "Overload," only the manual tells you exactly what is wrong.

5. Critical User Notes

The manual highlights several "Best Practices" that users frequently overlook:

1. Vibration Isolation: The SV-400 is sensitive to vibration. The manual strongly recommends using the instrument on a vibration-proof table or rubber mat.
2. Stylus Protection: The most common failure mode is stylus breakage due to rapid descent of the column. The manual advises using the fine-adjustment knob for final positioning.
3. Cutoff Value Selection: The manual provides a guide table for selecting the correct cutoff value ($\lambda_c$) based on the expected roughness of the surface. Using the wrong cutoff results in non-compliant data.

3.4. Measurement Operations

This is the core instructional section. It covers:

• Manual Measurement: How to position the stylus, set the traverse length, and start the measurement cycle.
• Parameter Settings: Navigating the menu to select cutoff wavelengths ($\lambda_c$), evaluation length, and filter types (Gaussian, 2CR, etc.).
• Auto-Run Functions: Instructions on using programmable features where the unit can take multiple measurements automatically (useful for repetitive inspection).
