Safeguard:

Overload protection: When the testing load is over 2%-5% of Max. Load, the system will unload.

Stroke protection: When the ram arrives at the upper limited position, the motor of oil pump will stop

Control Unit:

1. Constant speed piston stroke control:

Control range: Ram stroke speed

Setting range:0.5～50mm/min

2. Constant speed load control: Control range:2～100%of full scale load

3. Displacement-keeping control

4. Load-keeping control

5. Constant speed strain control range: 5～100% of full scale strain

6. Emergency shut down button & over load protection (auto stop) function equipped and return to the specified position automatically.

7. Control mode of operation: Auto/Manual function changeable

8. Automatic endpoints: The tester stops automatically while specimen breaks

9. Display of testing parameters: Value and real-time curve (Load and Stroke), available to display and switch from computer. Also the elongation can be calculated.
