®Name _____________________ Class ______________ Date _________PART II: Sensor Calibration and Equipment Setup• You do not need to calibrate the Photogate.1. The program assumes a 5 centimeter (0.05 m) spacing, leading-edge-to-leading-edge, forthe opaque bands on the Picket Fence. To change the default setting to another value,double-click on the Photogate & Picket Fence icon in the Experiment Setup window toopen the Sensor Setup window. Enter the correct value for the spacing of the opaque bandson your Picket Fence. Click OK to return to the ExperimentSetup window.2. Set up the equipment as shown. Mount the Photogate on thePulley Mounting Rod. Turn the Photogate head sideways so thatyou can drop a Picket Fence vertically from above the Photogateand have the Picket Fence move through the Photogate’sopening without hitting the Photogate.Trial Run of Data1. Before recording data for later analysis, experimentwith the Photogate and Picket Fence.• It is recommended that an old article of clothing,carpet sample, or piece of cardboard be placed onthe floor directly below the Photogate, so the PicketFence has a soft place to land.2. When everything is ready, start recording data. Dropthe Picket Fence vertically through the Photogate.Data recording begins when the Photogate beam isfirst blocked. Stop the recording once the PicketFence has passed completely through the Photogate.3. Rescale the data to fill the Graph window.4. Erase your trial run of data.ME-9377A PICKET FENCEP05 © 1999 PASCO scientific p. 31
