This instrument is in conformity with the design of update molding, compact in structures and beautiful in its outward appearances;
The highlight and long-life halogen tungsten lamps are adopted for the lighting source, clear in imaging and homogeneous in lighting;
The two high-and-low adjustable light intensities for transmission lighting can be adaptable for different measuring requirements;
The worktable is provided with three different travels for selection in accordance with the dimensions of the measured workpiece;
The up-and-down hoisting structure adopted for the projecting box can provide with a large focusing stroke in Z-direction;
The condenser can be adjusted manually; which according adjustment can be done in corresponding to different multiplying factors;
The tower dial with three objectives simultaneously would be very convenient for the replacement of multiplying factors and for accurate locating;
With an RS232 interface, this instrument can be equipped with two-coordinate measuring software with powerful functions.

This instrument series can efficiently measure sample plates, cross sections and surface shapes of various parts with complicated shapes; e.g., various cutting tools, tools and parts for sample plates, punching pieces, cams, threads, gears, taps, thread turning tools, molding milling cutters, etc. Thus, this instrument series would be suitable for machinery and instrumentation manufacturing sectors; and also one of the metrical instruments essential to the measuring rooms and workshops in related factories and plants.

2-D measuring software:
Acquisition functions:  Acquire dots, lines, circulars and arcs.
Construction functions:  Construct the dots acquired to form the straight line, the circular and the arc.
Combined computing functions: 
The combination calculation between “dot” and “dot” gives their dot distance and midpoint coordinate;
The combination calculation between “dot and line” gives their dot line distance;
The combination calculation between “straight line and straight line for their crossing” gives their intersecting point coordinate and their included angle;
The combination calculation between “straight line and straight line for their centering” gives the central line information for the two lines;
The combination calculation between “circular and circular” gives the information of the crossing points and the center distance of the circulars; and
The combination calculation between “circular and straight” gives the information of their crossing points and the distance from the center of the circular to the line.
Functions for the treatment of the shape and location tolerance: 
Measurement of the roundness between circular and arc;
Measurement of linearity;
Measurement of axiality;
Measurement of symmetry; and
Measurement of location.
Exchange of the coordinate system:
The coordinate transition between the rectangular coordinate and the pole coordinate
Establish the new coordinate and set the coordinate straight.
