The Mitutoyo Surftest SV-400 is a precision surface roughness tester known for its high accuracy and versatility in both laboratory and production line environments. While the specific "SV-400" nomenclature is often associated with the broader SV-3100 series or SJ-400 portable series in modern documentation, you can find the comprehensive technical resources through the official Mitutoyo Europe Downloads portal.

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. Powering on the display unit and the drive unit separately
A surprising number of users skip this. The manual explicitly states:
Measurement Range: Equipped with an 800µm detector range and resolution as fine as 0.000125µm.
Manual Solution: This indicates the amplitude exceeds the dynamic range. The manual instructs you to switch from "Standard" measurement mode to "Magnification Mode" (1x to 1000x) to reduce the signal sensitivity.
