: 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.

| | Possible Causes | Suggested Solutions | | :--- | :--- | :--- | | Inconsistent or Fluctuating Readings | Workpiece not properly seated; incorrect cutoff length selected; damaged or contaminated stylus tip; mechanical vibration; parameter misinterpretation | Re-seat the workpiece; select an appropriate cutoff (e.g., 0.8mm for milled surfaces); clean or replace the stylus; isolate the unit from vibration; verify measurement parameters in the manual. | | Device Fails to Power On | Loose power cord; blown internal fuse; faulty power supply; connection issue from previous maintenance | Check all power connections; inspect internal fuses (refer to manual for location); contact a qualified technician for power supply diagnosis. | | Stylus Skips or Drags | Excessive surface roughness; foreign debris on surface; worn or damaged stylus; traversing speed too high | Measure a smoother area; clean the surface; replace the stylus; reduce the traversing speed via the controller menu. | | Error Code Displayed | Specific internal fault (e.g., driver error, limit switch engaged) | Note the exact error code and refer to the "Error Messages" section of the user manual for the specific definition and corrective action. | | Communication Failure (RS-232C) | Incorrect baud rate; wrong parity or stop bits; faulty cable; outdated or incorrect drivers. | Consult the "Data Output" section of the manual to verify your communication settings match both the SV-400 and the receiving device. |

The Surftest SV-400 manual is a comprehensive document. Here is a breakdown of its likely contents:

Filter Switches: A common point of confusion for new users, as noted in a discussion forum, is the purpose of two switches on the back of the unit marked "filter 1" and "filter 2". The user manual is essential here, as it explains that these filters separate the roughness component from the waviness component of the surface profile. Incorrect filter settings will directly affect measurement readings. Typically, these settings would be selected based on the expected wavelength of the surface irregularities being measured. : Use the D

Watch the software displacement meter. Stop lowering when the stylus contacts the surface and registers within the neutral "green zone" of the measurement range. Step 4: Executing the Measurement

View the generated waveform profile. Export the numeric parameter array to a thermal printer or a connected PC database via the Mitutoyo Formtracepak software. 6. Preventive Maintenance and Care Step 2: Configuration : Standard : Select ISO,

Perform the initial axis initialization (homing) when prompted by the software. Step 2: Workpiece Setup
