5.3 Calibration of output voltage

In order to evaluate the experiment results quan-

titatively, it is necessary to know the precise rela-

tionship between the output voltage and the an-

gle of deflection.



Determine the angle of deflection geometri-

cally with the help of a ruler (see Fig. 1) and

match this with the corresponding output volt-

age.

5.4 Coupled pendulums

To set up a coupled pendulum arrangement (see

Fig. 2), it is necessary to use a second rod pen-

dulum, a coupling spring and a second voltage

sensor with adapter.

The following equipment is needed:

2 Rod pendulums

1 Coil spring, 3.3 N/m

2 Bench clamps

2 Stand rods, 1000 mm

1 Stand rod, 470 mm

4 Universal clamps

2 Voltage Sensors 10 V

2 Adapters, BNC Plug/4 mm Jacks

1 Data logger

1 Software

More information about digital measurement can

be found on the product's webpage in the 3B

Webshop.



Set up both pendulums as described in step

5.1.



You can increase the stability of the set-up by

adding a short stand rod between the two

long ones.

Subject to technical amendments

Insert the ends of the coil spring

in the pendulum rods to couple the two pen-

dulums

together.

6. Disposal

The packaging should be disposed of at local

recycling points.

Should you need to dis-

pose of the angle sen-

sor, never throw it away

normal

domestic

waste. Local regula-

tions for the disposal of

electrical

equipment

will apply.
