The operation keys on the front of the unit and under the sliding cover are well-labeled and easy to use
Internal memory stores up to 10 measurement conditions and one measured profile
Password protection prevents unintended operations and protects instrument settings
The display interface supports 16 interchangeable languages
LCD display mode can be freely switched between portrait and landscape as well as left-hand or right-hand direction
High-speed USB communication: Data can be transferred to and from a computer via the high-speed USB interface
Memory card support: The memory card slot lets you store large amounts of data onto a memory card
Drive unit can be separated from the display unit by using a cable, allowing more flexible measurement, and can be separated and reattached in one simple step
The user-friendly screen layout and arrow keys provide intuitive operability
Displayed settings can be changed easily by using the left and right arrow keys
Infrequently used keys are hidden under the sliding cover to prevent unintended operations
Complies with the following standards: JIS (JIS-B0601-2001, JIS-B0601-1994, JIS B0601-1982), VDA, ISO-1997, and ANSI

Extensive display features that assist measurement

The highly visible 2.4" color graphic LCD with backlight lets you view the screen easily even in dark environments
Pass/fail results are displayed in color
Assessed profiles, load curves, and amplitude distribution curves can be displayed in addition to calculation results
Assessed profiles can also be zoomed up and down
The display mode can be easily switched between portrait and landscape
Calculation results are displayed in large characters

Advanced data storage capabilities

Up to 10 measurement conditions can be stored in the internal memory. Conditions can be quickly read according to the workpiece.

Stylus alarm function

An alarm warns you when the cumulative measurement distance exceeds a preset limit. This feature can be used to prevent problems that would be caused by worn out styli. Any value can be specified as the limit.

Easy setting

Displayed settings can be easily changed by pressing the left and right arrow keys under the sliding cover. For example, these keys can be used to switch the cut-off value (λc) and the number of sampling lengths (N) on the measurement screen.

Setting parameters and recalculating results

The required parameters can be selected from the screen. The sub-menu also lets you specify detailed settings such as the tolerance. After completing measurement, the parameters can be changed and calculation can be executed again using the new parameters.
