=== Interpreting the Data ===
Keep in mind that the times recorded by the state setup of DataStudio are times of the leading and trailing edge of a voltage pulse which indicates when the "needle" broke and the stopped breaking the photo-gate beam. Be careful to ensure that the period used is extracted correctly from the raw data.

By taking data with various small mass positions which bracket the estimated equal period position in both the SMU and SMD orientations will allow two plots to be made. One plot is of the change of the SMU orientation's period as the mass moves, and the other will be of the SMD orientation. By plotting these data points on the same graph and plotting a best fit line for each data set, a crossing point can be found. This crossing point is the value where the periods should be precisely the same and should be used to calculate <math>g</math>.
