Features of 518 series altimeter:
1. Use a new, high-precision, high-resolution absolute origin linear encoder for position detection
2. Convenient icon keys
3. Inner/outer diameter measurement can be performed through a unique processing method (tracking, measuring, and detecting the vertices of a circle)
4. Multiple types of probes can be selected
5. Large LCD display with backlight illumination
6. Perform GO/± NG judgment by setting upper and lower limit tolerances. When the judgment result exceeds the tolerance range, the display backlight changes from green to red, and the tolerance judgment is clear at a glance.
