• Screw the stem with the magnetic base into the
displacement sensor and place it on the base plate.

• Loosen the screw on the displacement sensor’s
pulley. Wind a thread once around the pulley
and lead it out of the recess placing a loop
around the screw. Use the screw to fix the thread
in place.

• Attach one end of the thread to the hook of the
connector rod and suspend a weight from the
other end.

rod
• Use the suction pad to attach a second thread to
the base plate. Thread this over the groove in
the eccentric and use the other weight as a load
on the free end.
This load ensures that the pV diagram comes out better.
