Materials Testing Machine

Appendix A: Calibration

REMINDER: A PASCO Capstone workbook file about compliance calibration is available to download from the PASCO web 
site. Go to www.pasco.com and enter “Materials Testing System” in the Search window. In the web page that opens, select 
Materials Testing System. Click “Sample Labs” and then download the ZIP file for Lab 02.

Information covered in the “Lab 02 Compliance Calibration Tutorial” includes:

•

How a compliance calibration works.

•

How to create, save, and delete calibrations.

•

Hints and practice in making an accurate calibration.

NOTE: The default for the Materials Testing Machine in the software is 
a negative value for force and position as ‘negative’ when a tension 
force is applied. Although it is possible to use the Materials Testing 
Machine with negative values for force and position, it is easier to 
change the sign convention to be positive while you use the “Calibra-
tion Wizard” for the calibration procedure.

•

To change the sign for the force and position data, click the “Hard-
ware Setup” icon in the Tools palette.

•

In the Hardware Setup window, click the “Properties” icon (shaped 
like a gear wheel) to open the “Properties” window for the Materi-
als Testing Machine.

•

In the “Properties” window, note that the default for the 
“Change Sign” is an un-checked box. This means there is a 
positive value for both position and force when the Load Bar is 
moving down, as in a compression. 

•

If you want positive values for both position and force when 
the Load Bar is moving up, as in tension, click the check box 
for “Change Sign”. 

•

Click OK to close the “Properties” window.

•

Click the “Hardware Setup” icon to close the “Hardware 
Setup” window.

Prepare to use the software to calibrate the Material Testing 
Machine.
