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 (?c) 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.
