The instrument includes a 5.7" color LCD touchscreen display. After measurement is performed, a waveform with scale and ruler options is displayed for detailed analysis. The presentation corresponds to cissoidal calculations whereby one measurement can evaluate two different conditions. A simple contour analysis function is included (4 types: step, step amount, area and coordinate difference). In addition, a digital adjustment tilting (DAT) function is included for work piece leveling.
A manual column stand works with three new optional accessories (auto set unit, tilting adjustment unit and X-axis adjustment unit) to assist in setup and to enhance operability.
The Surftest SJ-411/412 enables statistic measurements of up to 3 parameters each for as many as 300 samples providing average, standard deviation, max, min, pass rate and histogram. Up to 10 measurement conditions and the stored data can be called up, displayed and printed using a built-in thermal printer. Also, the SJ-411/412 can store up to 10 measuring conditions in its on-board memory.
The system supports a micro-SD card (option) for storage of up to 10,000 text data, 500 measuring conditions, 1000 measuring data, 500 images (BMP), 500 statistic data or auto-save up to the last 10 measuring data. Total and sectional measurement results can be displayed in addition to evaluation and BAC/ADC curves.
The SJ-411/412 includes 16 selectable languages. A maximum of 5 custom styli can be recorded and calibrated independently.
The tool provides SPC output; RS-232C and external SW connectivity is also supported while available Mitutoyo software packages enable integration into high-level network environments for enterprise-wide functionality. Security is managed via a password lock.
