Statistical quality control software is available in visual, printed and menu-driven formats. Basic statistical functions include average and standard deviation as well as minimum and maximum values and range With the addition of disk drives, functions such as rate of rejection, subgrouping, compare, correlate and others, give you full statistical quality control. Profile and histogram plotting and printing are available and you can store from 40,000 data points in 360 memories to an unlimited number using optional disk drives.

Improved Accuracy and Reliability

Seiko engineers have taken much of the guesswork out of precision coating measurement. With the SFT-7000, speed, accuracy and reliability are highly improved. Programmable auto sample measurement, automatic spectrum and X-Ray intensity selection with override and automatic calibration make the SFT-7000 one of the most reliable systems available. Coordinate correction and position display functions make automatic measurements more precise than ever. Even the condition setting, such as the collimator selection, are protected by fail-safe shutters and automatic size detection and exchange functions, and help eliminate costly errors.

Sophisticated, Yet User-Friendly

The SFT-7000 series is designed to save you time and money by taking full advantage of today's most sophisticated microcomputer technology, The on-board computer is engineered around a 16-bit high-speed (8 MHz) 68000 CPU and comes equipped with a full keyboard and two 640K floppy
disk drives. Two video monitors (12" for data viewing and 10" for part sample viewing or simultaneous data and sample inspection for maximum operating efficiency and control.
A standard system memory records 360 measuring files, expandable to unlimited capacity with optional disk drives. The
The SFT-7000 series also makes it easy to transfer measurement and SFT-7000 series also makes it easy to transfer measurement and statistical data to own PC for further analysis via built-in RS-232-C and IEEE-488 ports.

Seiko's advanced Statistical Quality Control software programs are self-prompting and menu-driven and assure sophisticated results, with both visual and hard-copy output available, even in the hands of non-technical personnel. System operation sequences can be activated in one step by just entering a user- selected identifier. Even system calibration is semi-automatic.
Seiko's SFT-7000. The first user-friendly X-Ray coating thickness measurement system that allows you to economically expand your system as your application requirements become more complex.
