3. Operation
To conduct the experiment, the following apparatus is
additionally recommended:
1 Instrumentation amplifier for students’ experiments
8532161
1 x 4-mm high-frequency BNC cable
U11257
1 Multimeter ESCOLA 10
8531160
1 Stand base
8611210
In order to prevent any drifting of the output voltage,
the metal housing of the thermopile should be at
room temperature.
•
After setting up the experiment, wait for a few
minutes before taking readings.
Readings may be made incorrect due to the influence
of body heat or other external influences.
•
Do not touch the apparatus while taking read-
ings.
•
Avoid direct sunlight and do not set up the appa-
ratus in the vicinity of a heater/radiator.
•
Set up the thermopile approx. 3 cm away from
the object of the experiment (e.g. Leslie’s cube
8442830).
•
Connect up the instrumentation amplifier and
the multimeter.
