• stiffness (Disp1, Disp2)
The software will calculate the stiffness of the specimen between Disp1, and
Disp2, by looking up the loads (L
1
and L
2
) corresponding to the first
occurrence of these two displacements (D
1
and D
2
) and returning the value
of:
(L
1
- L

) / (D
1
- D

)
in the context of spring testing this would be called a ‘spring rate’ calculation.
• Pressing the [1] key will toggle between ‘ON’
& ‘OFF’. If this calculation is active the difference between the ‘absolute zero
