Yes. 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.
No. If you need to measure waviness (Wt) or primary profile (P) parameters frequently, upgrade. The SV-400 does them, but it is painfully slow to set up.
The official manual for the Surftest SV-400 is typically a comprehensive technical document (often exceeding 100 pages) divided into distinct chapters. It is designed to take a user from initial setup to complex statistical analysis.
The SV-400 is capable of calculating a wide array of roughness parameters. The manual provides definitions and formulas for:
Websites like ManualMachine.com, ManualsLib.com, or IndustrialManuals.com occasionally host scanned copies. Warning: Ensure the scan is readable (300+ DPI) and contains the appendices (usually missing in pirated copies).
The manual begins with standard safety icons and warnings. Key points emphasized include:

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.
Place the detector on the calibration stage and ensure the lay lines of the specimen are perpendicular to the tracing direction. Positioning and Setup DAT (Digital Adjustment Tilting)

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.
: Avoid using the device in environments with volatile gases, strong electric fields, or corrosive air. Surftest SJ-400 - Mitutoyo
Mitutoyo Surftest SV-400 series (often grouped with the SJ-400 or SV-2100 families) is a high-precision, skidless surface roughness tester designed for laboratory and high-end shop floor applications. While "SV-400" specifically often refers to the drive unit or specialized system configurations, it typically utilizes the control interfaces and software common to the SJ-400 or SV-2100 series.
Below is a comprehensive guide based on the standard operating procedures and specifications for these Mitutoyo measuring systems. 1. Key Technical Specifications
The SV-400 series is distinguished by its skidless measurement 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: Unless you need nanotechnology (1nm Ra), this machine
Evaluation Standards: Conforms to ISO, DIN, ANSI, and JIS (1982/1994/2001).
Parameters: Supports up to 36 (SJ-400) or 43 (SV-2100) analysis parameters, including 2. Initial Setup and Calibration
Before measurement, the system must be calibrated using a precision reference specimen to ensure gain adjustment is accurate.
Power On: Connect the AC adapter or ensure the rechargeable battery is charged.
Mounting: Place the drive unit on a manual or motorized column stand for stability. Auto-Calibration: Navigate to the Calibration screen on the touch panel.
Place the detector on the provided Roughness Specimen (typically
Enter the calibrated value from the specimen's certificate into the control unit.
Press the Start button; the system automatically adjusts the gain. 3. Measurement Procedure The SV-400 does them, but it is painfully slow to set up
The SV-400's primary advantage is the D.A.T. (Digital Adjustment Tilting) function, which guides the user through leveling the workpiece. Mitutoyo Surftest SJ-400 Surface - Metrology Parts
