4. software introduction

4.1 auto stop: crossbeam auto stop when sample break

4.2 auto save: test parameters, test curves and test results can be auto saved after test

4.3 speed adjusting: speed of crossbeam can be adjusted during test automatically or manually

4.4 auto calibrating: system can do auto calibrating

4.5 easy operate: computer software can auto finish test procedures, measuring, displaying and analyze test data.

4.6 batch test: for test sample with same parameters, test can be finished in order after one time setting

4.7 display mode: data and curves can be displayed during test in real time

4.8 curve scanning: test curves can be re-analyzed after test, test date of each point on the test curve can be displayed via mouse click

4.9 curve choosing: stress-strain curve, force-displacement curve, force-time curve, displacement-time curve can be chosen accords with test requirement.

4.10 test report: test report can be printed in different format

4.11 stroke protection: mechanism and program control protecting functions

4.11 over load protecting: when force is more than 3%-5%of rated capacity, machine will auto stop.
