5. Check the bent mean offset values.
The bent mean values are the average of both the bent front and bent
back values taken in steps 3 and 4. These values will be used when the
Specimen Bent selection is active in the Use Offset section of the
Align tab.
Also included are the X and Y bending components due to the specimen
and the load unit:
• bending strain due to straightening the specimen (bent mean offset
relative to the gauge offset)
Xs - bending strain in the x-axis
Ys - bending strain in the y-axis
• bending strain due to load unit misalignment (bent front offset relative
to the bent mean offset)
Xm - bending strain in the x-axis
Ym - bending strain in the y-axis
