98 Collect data; do you see what you expected? If not, adjust the sensors until you get what you expect. f) You should see the position oscillate around 0 meters (to within about +/- 0.001 m), and the force oscillate around 0 Newtons (to within about +/- 0.01 N). The amplitude of the motion should be around 5–10 cm. Look carefully; if the centers of oscillation aren't zero, you may have to adjust the readings manually to force them to zero. Adjust to zero manually: Return the system to equilibrium and zero all sensors. Collect data with the system at rest. Use Analyze:Statistics to determine the average position of the mass. Click on the oval Labpro icon to bring up the Sensors Window, and click on the motion sensor. On the pop-up menu, click Set Offset. A box will pop up with an initial value of the offset. Subtract the average position from the offset and enter this difference as the new offset, then click OK. (E.g. if the average position is 0.0123 and the initial offset is -0.612345, the new offset is -0.624645.) Collect data again and the position should have an average very close to zero. Close the Sensors window. Each time you zero the motion detector you will need to repeat this. Use
