WAW-100 and 600kN load capacity of Elctrohydrualic sero Universal Testing Machine how to fix or Adjust strain rate

Hi, i am going to run my Experiment for tensile testing of different steel samples at different strain rates ofcourse it is Medium strain rate (1*10-1  - 1*103 s-1 ). and my quetion here is how to adjust my strain rates on this machine? is the cross head speed a strain rate?  if that is the case i think the cross head speed of the machine i am going to use is max. 15 mm/s. so  it is very small for my ranges to apply . any one can help me or give me comment on this issue.

I appriciate any help that comes to me.

thank you
