Interfaces
A variety of interfaces supplied as standard
The external device interfaces that come as standard include USB, RS232C, SPC output and footswitch I/F.
Data storage
Memory card (optional) is supported
The measurement conditions and data can be stored in a memory card (optional) and recalled as required. This enables batch analysis and printout of data after on-site measurement.
•Measurement condition
Internal memory: 10 sets Memory card: 500 sets
•Measurement result
Memory card: 1000 sets
Key-sheet buttons
A sturdy key-sheet-button panel with superior durability in any environment is provided. For repeat measurement of the same work, simply pressing the start switch can complete measurement, analysis and printout.
Printer
High-speed printer prints out measurement results on site
A high-quality, high-speed thermal printer prints out measurement results. It can also print a BAC curve or an ADC curve as well as calculated results and assessed profiles. These results and profiles are printed out in landscape format, just as they appear on the color-graphic LCD.
Password protection
Access to functions can be restricted by a password
A pre-registered password can limit use of measurement conditions and other settings to the tester’s administrator.

Enhanced measuring functions
Your choice of skidless or skidded measurement
•Skidless measurement
Skidless measurement is where surface features are measured relative to the drive unit reference surface. This measures waviness and finely stepped features accurately, in addition to surface roughnness, but range is limited to the stylus travel available. The SJ-410 series supports a variety of surface feature measurements simply by replacing the stylus.

Patent registered in Japan, U.S.A.. Patent pending in Germany
•Skidded measurement
In skidded measurements, surface features are measured with reference to a skid following close behind the stylus. This cannot measure waviness and stepped features exactly but the range of movement within which measurement can be made is greater because the skid tracks the workpiece surface contour.

Powerful support for leveling
Patent registered in Japan, U.S.A.. Patent pending in Germany
The height/tilt adjustment unit comes as standard for leveling the drive unit prior to making skidless measurements and, supported by guidance from the unique D.A.T. function, makes it easy to achieve highly accurate alignment.
