Mitutoyo Surftest Sv-400 User Manual |work|

Allows for the measurement of waviness and ultra-fine stepped features by switching modes.

Covers grounding requirements (critical to avoid electrical noise on the measurement signal), fuse ratings, and power voltage switches (100V, 120V, 220V, 240V).

This article serves as a deep dive into the importance of this manual, breaking down its contents, explaining how to navigate its technicalities, and providing a starting point for users who may have misplaced their original copy. Whether you are a seasoned metrologist or a machinist new to quality assurance, understanding the manual is the first step toward reliable data. mitutoyo surftest sv-400 user manual

The SV-400 is often praised for its modular design. It can accommodate various detectors (stylus arms) and can be fitted with optional units like a Y-axis table or a motorized column. Because of this modularity, a single "universal" approach to operation is impossible. The user manual is not just a set of instructions; it is the configuration map that tells the operator how to set up the specific arrangement of their unit. Without the manual, an operator might apply the wrong stylus force, use an incorrect cut-off value, or misinterpret the profile graph, leading to failed inspections and scrapped parts.

Whether you are a seasoned quality control engineer, a new lab technician, or someone who just acquired a used SV-400, this article will explain why the original user manual is indispensable, what critical information it contains, and how to use it to avoid costly errors.

Before dissecting the manual, it is vital to understand the machine it governs. The Mitutoyo Surftest SV-400 is a skidless surface roughness tester. Unlike skid-type portable roughness gauges, the SV-400 uses a precision drive unit that moves the stylus independently of the workpiece surface irregularities. This allows it to measure parameters that require a true reference, such as waviness and primary profile profiles, in addition to standard roughness (Ra).

Have a specific question about your SV-400? Consult your manual. If you still need help, contact an authorized Mitutoyo service center. Never attempt to disassemble the detector unit or column without factory guidance—the precision alignment is critical. Whether you are a seasoned metrologist or a

Detailed calibration using the included reference specimen. It shows the expected value of the standard (e.g., 3.02 µm Ra) and the tolerance (+/- 5%). It also explains how to adjust the "multiplier" value in the controller if the unit drifts.

The SV-400 often includes RS-232C or Centronics (parallel) ports for printing or connecting to a PC. This section describes pin assignments, baud rates (300, 600, 1200, 2400, 4800, 9600), and handshaking protocols. If you want to connect the SV-400 to a modern PC via a USB-to-serial adapter, this information is vital.
