: Since the SV-400 and SJ-400 series share core measurement parameters and logic, this manual is often used as a primary reference for operational basics like calibration and stylus handling. It is available on Mitutoyo America Key Technical Specifications (SV-400)

The SV-400 is typically used for high-accuracy surface roughness measurements and features: Measurement Parameters : Supports standard parameters including Calibration : Requires the 178-611 Reference Step Specimen

(2 µm / 10 µm nominal values) to calibrate detector sensitivity. Software Compatibility : Often interfaces with SURFPAK-SV FORMTRACEPAK for advanced contour and roughness analysis. 한국 PME Maintenance & Parts Stylus & Detectors Check the four leveling feet

The Leveling Nightmare

The manual shows a bubble level on the base. However, the SV-400 is incredibly sensitive to twist. If your surface roughness readings are fluctuating wildly: Cond 1: Ra

1. Check the four leveling feet.
2. Loosen the locking nuts on the feet.
3. Do not just level it; "Rock" it. Place the stylus on a gauge block. If the reading changes when you push the table slightly, your granite base is twisting.

3.3. Preparation and Setup

Before measurement, the manual outlines specific preparation steps:

• Leveling: Adjusting the leveling feet to ensure the instrument is stable.
• Calibration: The manual details the procedure for calibrating the detector using a calibration specimen (roughness standard). This is essential for ensuring the vertical amplification is accurate.
• Workpiece Placement: Instructions on how to secure the workpiece to prevent vibration, which can distort roughness readings.

Chapter 4: Measurement Conditions (The "Condition" File)

The SV-400 can store up to 10 measurement conditions (Cond 0 to Cond 9). The manual provides a matrix table showing which parameters are active per condition. For example:

• Cond 1: Ra, Rz, Ry (JIS)
• Cond 4: Rmax, Rtm (DIN/ISO)

Chapter 3: Basic Measurement Operation (Step-by-Step)

This is the heart of the manual. It explains:

1. Powering on the display unit and the drive unit separately.
2. Zero adjustment – Placing the stylus on the reference flat.
3. Cutoff length (λc) selection: 0.25mm, 0.8mm, or 2.5mm.
4. Traversing length (Lt) calculation based on your part geometry.
