The measuring principle of this instrument is rectangular coordinate measurement method, that is, the coordinate points of the surface contour of the measured part are mapped by X-axis and Z1-axis sensors, and the coordinate point data measured by the sensors are transmitted to the upper PC through electrical components, and the software performs mathematical operation on the collected original coordinate data and marks the required engineering measurement items. 

This instrument can be compared with the performance of imported instruments, and all indicators have reached international standards. The instrument meets the requirements of national standards GB/T3505-2000, GB/T6062-2001, GB/T10610-1998, and international standards ISO 5436, ISO 1562 and ISO 4287.
