e.3 photoelectric encoder inputs; the orthogonal codes pulse can be 5MHZ; it can find and correct mistakes, identify, count and so on.

f.There is no manual component in electronic measurement and control system; it can ensure to change easily.

g.Build-in CPLD, it can high-speed calculate and real-time process.

7.Functions and features of MaxTest:

We can configur multiple pressure sensor according to customers requirement.

It equips special test software, can be general used, and has many test standard for metal material and non-metal material, and we can design special test standard according to customers requirement.

Users can edit all kinds of test report according to their wishes.

Bilding block design: MaxTest adopts  building block design, the software includes:

a. Test moduletest software main interface, test control center;

b. Parameter management authority: Operators of non-debug can not enter the parameters this module;

c. New data module: can make the new test parameters data by a single or batch of;

d. Curve analysis module: the users can analysis the curve after the test. The user can find the every point of curve by the mouse.

e. Data inquiry module: the user can quickly find test data they need from the thousands of test data if they know nay parameter.

f. Parameter debugging module: control unit of machine control parameter;

g. Report print module:  edit test report by the needs arbitrarily. 

8. MaxTest is with many ancillary procedure:

a. Debugging toolbox procedure:  open it, and then can change the configuration parameters of system;

b. Batch processing program: it can process the test data that they have the same batch, serial date and other same signal.

c.Report processing program: MaxTest.DOC, MaxTest.xls and high-defined report, can make the user edit the format statements.

d.MaxProgrammer:  the user can order the special control program by the actual needs.

e.Intelligent operation, the users provide the suggest airing the test and operate it easily.

f. Test force overload protection; it can record and can be found later.

9. Main features:

a. Load measurement: high-precision oil pressure sensor, high-precision oil tank piston; they ensure the high precision and high reliability. The linear repeatability is good; the impact is strong, reliable and has long life.

b.Displacement measurement: import photoelectric encoder, high-precision, reliable.

c.Deformation measurement: high-precision strain extensometer is reliable and economical.

d.Automatic clamping: single hydraulic clamping oil supply; automatic and reliable clamping, high safety.

e. Multiple protection: double protection for hardware and software; double protection piston travel for mechanical and electric; protect itself automatically when exceeding 2~10% of       Max. load.

f. Automatic calibration: calibrate the load, deformation and displacement automatically.

g.Getting the test results: get the  ReH ReLFmRp0.2Rt0.5RmE results automatically.

h.Management of database: manage the test machine software by Access database.

i. Reserve the data interface, can be connected with Internet directly and share the resources.

j. Compact structure: more reasonable structure. Lowering the height that the test space is same.

k. Worm and worm wheel drive structure adjusts the test space, airing the curse, not to need the leading screw. The driveline and positioning is completely separated. The loading system geometric center and force center is consistent. Thus ensures the coaxial of upper and lower jaw and the durability of the host machine.
