To achieve specified accuracy, place the SV-400 in an environment that meets these criteria:

radius). The stylus tracks surface peaks and valleys, translating mechanical movement into electrical signals.

Press START . The stylus will trace the specimen.

Achieving absolute precision in modern manufacturing requires more than just a good eye; it demands reliable, highly accurate surface texture analysis. The (often referenced in tandem with the highly popular SJ-400 portable series) stands as a benchmark for high-accuracy, portable, and versatile surface roughness testing. Whether you are operating it on a bustling production line or in a climate-controlled quality assurance laboratory, understanding the full operational lifecycle of this instrument is essential for reliable QA/QC workflows.

Whether you are using or the dedicated remote control unit ?

Before initiating any measurement, familiarize yourself with the primary components of the Surftest SV-400/SJ-400 system. The equipment typically breaks down into three core parts:

is a high-performance, portable surface roughness tester equipped with a skidless detector and a straight drive unit, designed for superior high-accuracy measurements.

for maximum accuracy. Avoid direct sunlight and air conditioning drafts.

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

Use a lint-free cloth and high-purity isopropyl alcohol to clean the reference block.
