YF-D Series is the basic type manual Video Measuring System developed by Yihui. It has been widely used in machinery, electronics, metalwork, mould , plastic and other industries for precision measurement. 1. It can measure point, line, circle, arc and oval, rectangular and improve the accuracy with the multi-point positioning function. 2. In metrology terms, the machine can test and dimension width, length, height, thickness, diameter, angel, straightness, flatness, perpendicularity, circular degree, coaxiality, etc. 3. Combination of measurements, center structure and the intersection of structure, the midpoint of construction, line structure, a round structure and structural point of view. II Features                            Motorized in Z axis, it can satisfy precision focus and high accuracy non-contact height, depth measurement with easy clicks on metrology software.
2. It can measure point, line, circle, arc and oval, rectangular with the multipoint positioning function, combination of measurements, center structure and the intersection of structure, the midpoint of construction, line structure, a round structure. 3. Various functions of data processing, display, input and output, Measurement data output Word, Excel and Auto CAD directly to conduct statistical analysis, particularly, and the work piece straightening function is very useful. 4. Digital measurement and data processing system are made up by the two coordinate's studio, the optical grating and the SDK -3000 data card. 5. It has RS232 interface with a computer and specialized measurement software which can also processes and output circular mapping.
