3. Operation
To conduct the experiment, the following apparatus is
additionally recommended:
1 Instrumentation amplifier for students' experiments
1 x 4-mm high-frequency BNC cable
1 Multimeter ESCOLA 10
1 Stand base
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.
