Features:
1. Relation curves between surplus testing power(or LESR) and the time are available.
2. Specimen Stress relaxation of 1000 hours could be calculated.
3. Loading speed 100-5000N/S, speed is variable. 
4. Automatically calculate stress relaxation characteristic(such as stress relaxation rate) 
and print complete testing report.
5. Load and displacement are calibrated by numbers.
6. Test results are saved and records of testing process could be consulted.
7. The system automatically adjusts coordinates under different testing condition.
 Complete curve is indicated during test procedure.
8. Test parameters can be automatically saved, assigned out and re-set.
9. Data collection: You can use the mouse to collect data from the curve after the test 
completed.
10. Stainless steel housing.
