Video edge probes with auto best-fit function
When the operator clicks the point to be measured, the system automatically rotates the probes, sets them at the optimum position, and sets the probe size, all automatically.

Advanced intelligent search
Finding a skewed part location and correcting positional deviations of the edge probing points within a part are programmable by a pattern-matching feature, eliminating possible measurement errors.
APS (Auto Position Search)
Thanks to this function, the operator no longer needs to manually place multiple workpieces in proper alignment; the iNEXIV automatically searches workpiece location and its orientation.
MPS (Multi-Pattern Search)
Automatically corrects deviations between the edge probing points programmed in a teaching file as well as irregular feature positions without edge probing error.
