Specific features of the Suftest SJ-210 Series

Extensive Display Features

Whether you are working in a well-lit environment or in a darkened space, the Suftest SJ-210 Series portable roughness test comes with a 2.4-inch color graphic LCD screen that uses a backlight feature and displays pass or fail results in a color format. Capable of displaying assessed profiles, load curves, amplitude distribution, and calculation results in both landscape and portrait orientations, these roughness testers can tackle any measurement conundrum you may find yourself in. Profiles come with a zoom feature and all calculations are displayed in large characters to increase visibility. Finally, the display settings are easy to adjust. By using the arrow keys located under the sliding cover, you can quickly switch the cutoff value or the number of sampling lengths that are shown on the measurement screen at any one time.

           

Advanced Data Storage

Data from your Suftest SJ-210 Series portable roughness tester has never been more straightforward. Depending on the type of workpiece you are measuring, you can use any of the 10 measurement conditions you are able to store within the tool’s internal memory. If that is not enough storage space, an optional memory card can boost these devices memory even more, with 10000 capacities for measured profiles and calculation results, 500 capacities for measurement conditions, and 500 capacities for display images. Data transfer has also been mastered by the Suftest SJ-210 Series. The USB option comes standard in each device, but you can also use the RS-232C output, Digimatic output, printer output, or foot switch output.

 

Stylus Alarm

Any metrologist knows that when you run into a worn out stylus, all of your measurements could be negatively impacted. Well, lucky for users, the Suftest SJ-210 Series portable roughness tester comes pre-built with a stylus alarm to prevent such circumstances. When the cumulative measurement distance has exceeded a predetermined limit that you have set, the stylus alarm function warns you of the occurrence. It is up to you what you set as the specified limit, allowing for flexibility depending on the types of measurements that you conduct and how conservative you would like to be concerning stylus wearing. Another helpful stylus feature on the Suftest SJ-210 Series is the way these tools indicate when the stylus makes contact with a workpiece by a color coded alert in the display. This can be essential when the measurement surface is not visible or is restricted in some way.

 

Parameters and Recalculations

The Suftest SJ-210 Series portable surface roughness testers allow you to select parameter requirements and specify details such as tolerance right from the device screen. If you have completed the measurement you need, but would like to recalculate the measurement under different parameters, either for comparison or to test limits, then doing so is simple. All you need to do is change the parameters to what you would like and then recalculate the measurement.

 

Available Detectors and Drive Units

Depending on the choice you make regarding detector, drive unit, and display unit, the Suftest SJ-210 Series allows you to create a number of combinations to make these devices most suitable to your needs. The driver is easy to detach and reattach, and come either with measuring force of 0.75mN, stylus tip radium 2μm, and stylus tip angle of 60° or measuring force of 4mN, stylus tip radius 5μm, and stylus tip angle of 90°. The selectable drive units for the Suftest SJ-210 Series come in three types. First, the standard drive unit is the most popular and applicable across many contexts. Second, the transverse tracing drive unit is best when taking a measurement of narrow or shrouded parts of a workpiece, like EDM parts or a crankshaft. And third, the retractable drive unit that is immune from damage when it is used through insertion into a feature that cannot be seen easily. Optional detectors are available for small or extra small holes, as well as gear tooth surfaces and deep grooves.

 

Welcome to the Suftest SJ-310 Series

The Suftest SJ-310 Series is known for being highly functional and easy to use all at once. Intuitive and easy operation are at the core of the Suftest SJ-310 Series portable surface roughness tester design. With a 5.7-inch color graphic touch screen and an integrated high-speed printer, the entire process from measurement to data printout can be done with the touch of a single button. Applicable to any work environment, the Suftest SJ-310 Series can be connected directly to a PC via USB for measurement control or results inspection. The Suftest SJ-310 Series can also save and transmit results and any required recalculations through a memory card using text format. With the standard purchase of a Suftest SJ-310 Series portable surface roughness tester you will get one of two directors, and your choice of drive units, including a standard drive unit, a transverse tracing drive unit, and a retractable drive unit. This series of portable surface roughness testers is unique and designed for metrologists like you to be adaptable to a range of roughness measurement contexts.

 

Display and Data with the Suftest SJ-310 Series

The display on the Suftest SJ-310 Series portable surface roughness testers can be easily switched between text and icon. This user-oriented ability makes this tool easy to use.

You can easily select the assessment conditions from the provided display list. Whether you are using a standard assessment or setting a parameter, your measurement is still only a button away. When useful, you can also enter any assessment conditions by using ISO or JIS surface texture symbols. This can help with quick translations between metrologists. When data that you no longer want or need gets included in your data set, the Suftest SJ-310 Series allows you to easily delete unwanted portions of your data without getting rid of the important data you have already captured. When looking at waveform data, using the zoom feature allows you to magnify or shrink waveforms to more easily determine the coordinate difference between two points. Additionally, the zoom feature allows you to check for status irregularities without needing a printout. All of your pass/fail results can be displayed in color on the Suftest SJ-310 Series portable surface roughness testers, making result determinations quick and straightforward.

 

Roughness Results and Challenging Measurements with the Suftest SJ-310 Series

Get what you need from your measurement data with the Suftest SJ-310 Series portable surface roughness testers. The results of your measurements can be displayed in 1-parameter form, profile form, 4-parameter form, or trace display. Measurements are easy to recalculate after modifying the required assessment conditions to switch between standard, profile, and parameter. In fact, without even using the recalculating feature of the Suftest SJ-310 Series portable surface roughness tester you are able to analyze two different assessment profiles using the result of a single measurement. Managing use and replacement of the roughness tester stylus has never been easier than with the Suftest SJ-310 Series.

GLOSSARY TERMS

Liquid Crystal Display (LCD)

Liquid crystal displays use a backlight that lights individual pixels that make up a display screen. By using a backlighting system instead of firing electrons at a glass screen, the LCD system allows for millions of color combinations using individual pixels that have a red, blue, and green light function that can be turned on or off. LCD screens provide a more evenly lit surface that is polarized, leading to better readability and a clearer display.
