Measurement software: it can measure points, lines, circles, arcs, angles, distances, ellipses, rectangles, continuous curves, tilt corrections, plane corrections, and origin setting. The measurement results display the tolerance value, roundness, straightness, position and perpendicularity. The degree of parallelism can be directly exported and imported into Dxf, Word, Excel, and Spc files for editing which is suitable for batch testing for customer report programming. At the same time, part of and the entire product can be photographed and scanned, and the size and image of the entire product can be recorded and archived, then the dimensional error marked on the picture is clear at a glance.
