1. Applications and features:
WDW microcomputer controlled electronic universal testing machine (ordinary type) use uprights and ball- screw to fix the upper beam and working table. It adopts interflow stepping motor and driver to drive ball-screw then make middle beam moving. Stretching, compressing, bending, peeling, shearing, tearing, puncturing, bursting and high or low temperature test according to standard such as GB, ISO, ASTM, JIS, DIN etc.

3. Functions
1）Software packages
The computer data processing software is based on WindowsXP operating system platform. It can satisfy different testing materials and complete tensile, compression and bending tests.
Features of the software package:
(1) Measuring the force value, deformation and displacement synchronously.
(2) Test curve real-time display
(3) Can delete arbitrary testing result arbitrarily.
(4) Can zoom and print testing curve. Can select parameter points on the curve (yield point, elastic, etc).
(5) Use VB+SQL language to calculate parameter, it is reliable and convenient.
(6) Can obtain metal materials tensile( pressure) strength, yield strength, δ0.2, disproportional strength, elongation strength etc.
2) Microcomputer system: Use the Lenovo brand microcomputer as host machine to finish the testing setting setup, data acquisition, display and print test results etc(include: main engine, 17 "LCD and large capacity hard disk); equipped with KQL-PowerTest2001 in English and Chinese version which is intelligent test software packages; Can provide standard measurement and judgment of performance parameter for all kinds of material, add up and processing the data; output various requirements of the test report and test format curve.
3) Computed mode: Hand valve operation, and equipped with manual control operation box, contains 6 buttons (rise，fall, upper clamping, bottom clamping, upper loosen, bottom loosen), the operation more convenient, safe and reliable.
4) Safety protection: Equipped with oil cylinder protection system, overload autostop system, overcurrent outostop system and emergency switch protect function.
