340 to generate the CO

response curve.
The response curve of photosynthesis vs. air temperature can be seen by pressing “T” (shift, shift, 7)
when measuring photosynthesis. The instrument will ask for the number of steps for the temperature
response curve, and then will direct the CI-510CS (CI-301CS) Temperature Controller to start at a
low temperature and increase the air temperature in the leaf chamber to a high temperature in that
number of steps. Make sure the temperature control knob is turned all the way counterclockwise.
Only the CI-510CS ordered with the CI-340 can be automatically controlled by the CI-340 to
generate the temperature response curve.
Pressing “EXIT” while in the graph mode can stop the response curve. This will return the display to
the alpha/numeric mode and stop any further changes to the controlled parameters. It will also erase
the graph.
