Software Parameters One increment is the smallest unit of motion the motor can move, 1.8° (Anaheim Automation 34Y1) This may change as the moving system is assembled Files names and/or location to store data and images The number of load data points to take at each increment P09045: Membrane Characterization Test Stand P09045: Membrane Characterization Test Stand 1/2/2019 5

Software Flow Move One Increment LabView communicates with the motor controller and tells the motor to rotate the amount corresponding to one increment Measure and Save Load Cell Data LabView measures a given number of samples from the load cell and records it to a predetermined file Take Picture LabView tells the camera to take a single frame of the membrane at the current displacement Reach Max Number of Increments Condition If the maximum number of iterations has been reached, end the program and proceed to analysis If the maximum number of iterations has not been reached repeat from step 1 P09045: Membrane Characterization Test Stand P09045: Membrane Characterization Test Stand 1/2/2019 6
