If there are centrifugal force apparatus (347 21) available, they can be upgraded by means of the centrifugal force adapter (524 0681). Handling and measuring results of this combination do not differ from those of the centrifugal force apparatus S (524 068). Before the centrifugal force apparatus (347 21) is used with the centrifugal force adapter (524 0681) for the first time, the zero and the gain at the centrifugal force apparatus should once be readjusted according to the instruction sheet of the centrifugal force adapter.
Experiment setup (see drawing)
Use the bench clamp to fix the centrifugal force apparatus to the table. The light barrier is set up by means of the stand rod and the stand base so that the rotating arm can freely rotate between the legs of the light barrier; the light beam should not be interrupted by the weight. The centrifugal force apparatus is connected to Input B and the light barrier via the 6-pole cable to the timer box at Input A of the Sensor-CASSY. The power supply is connected to the driving motor of the centrifugal force apparatus via two connecting leads. The maximum voltage for driving the motor should be selected so that the force measuring range does not exceed 15 N.
