Mechanical Testing System Load Cell Measures load in lbs or N Linear Actuator Measures displacement in inches or mm Perform calibration, initialize software set-ups, and insert the appropriate jigs. After the test, load vs. time and displacement vs. time are recorded. What is next? Depends on what questions are asked. PC with the hardware specific software
