• The spindle moves four times faster than that of the standard micrometer, enabling faster, easier measurement even when it is repeated many times over.
• The approach speed warning function can detect collision with a workpiece at excessive speed, helping inexperienced users obtain reliable and accurate measurement results.
• The calculation function can calculate offsets added to measurement results before they are passed to a machine. This eliminates errors and the effort needed for calculation, helping reduce the number of rejected machined items.
• The Calibration alert function helps with effective measuring instrument management.
• Bidirectional serial communication supported.
