• X Data Dimension, Y Data Dimension: These inputs specify the
number of columns and rows in the indent array. For example, if
X Data Dimension and Y Data Dimension are set to 10 and 10,
then 100 indentation tests are executed. These inputs should be
set after consideration of expected size of each indentation,
testing domain and desired test time (each indent requires
approximately 1 second to complete).
• X Start Position, X Stop Position: Positions relative to the red
crosshairs at the center of the microscope image defining the
left-most and right-most columns in the array of indents.
• Y Start Position, Y Stop Position: Positions relative to the red
crosshairs at the center of the microscope image defining the
left-most and right-most columns in the array of indents.
Click the Run button.

Once testing is complete, the software will prompt the user to save the
file.
Input a file name and click Save.

The 2D data is available by selecting the Channels tab as shown in
Figure H-6 on page H-8.
The 3D data is available by selecting the 3D tab as shown in
on page H-9.
The available results are:
Points Excluded: Points rendered invalid and excluded from reported
results by the Filter Graph function (Help menu provides further
information on this subject).
Disp Into Surface (nm): Peak indentation displacement, averaged over
all valid indents in the test array.
Modulus (GPa): Young's modulus, averaged over all valid indents in
the test array.
Modulus SD (GPa): Standard deviation of valid Young's modulus
measurements for the test array.
Hardness (GPa): Hardness, averaged over all valid indents in the test
array.
Hardness SD (GPa): Standard deviation of valid hardness
measurements for the test array.
Stiffness (N/m): Contact stiffness, averaged over all valid indents in the
test array. If the contact stiffness is more than 10 % of the frame
stiffness, best results may require the determination of frame stiffness
