• Change the name of the data run (Run #1) containing the calibration data to “Cal”.*
DataStudio Set-up
1. Prepare the calculation for “Calibrated Displacement(F)”. In the Calculator window, select the “Cali-
brated Displacement(F)” calculation and define the variables.
• Drag “Displacement(t) vs Coupon Force(t) (mm)” to “Please define variable ‘Displacement’.” (Figure 13)
• Drag “Cal” to “Please define variable ‘Cal’” in the Calculator window. (DataStudio will display a warning
box stating that a “single run is selected”. Click the Yes button in that box.)
2. Prepare the calculation for “Stress(F)”. In the Calculator window,
select the defined function “Stress(F) = Force/Area”. In the Vari-
ables section, enter the cross-sectional Area of the coupon in square
millimeters. See the Test Coupons Specifications section for the
cross-sectional Area. (The cross-section Area in this example is
0.303.)
* To rename a data run, click the run name (e.g. “Run #1”) where it appears in the Data List. Wait about 1 second
then click it again. Enter the new name. A dialog box will appear. Select Yes. (If a window titled “Data Properties”
appears, you didn't wait long enough after the first click; close that window and try again.)
