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
1000764
1 Coil spring, 3.3 N/m
1002945
2 Bench clamps
1002832
2 Stand rods, 1000 mm
1002936
1 Stand rod, 470 mm
1002934
4 Universal clamps
1002830
2 Voltage Sensors 10 V
1021682
2 Adapters, BNC Plug/4 mm Jacks
1002750
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.

into the holes
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
in normal domestic
waste. Local regula-
tions for the disposal of
electrical
equipment
will apply.
