Control Setpoints can be changed dynamically in Measure Mode, but these changes are temporary and
are NOT saved in the Parameters File. During measurements or while simply observing gas exchange,
click on the button for the Setpoint(s) that you wish to change and the Ciras Control Values dialog
appears. With this dialog open, you can change one or all of the Control Setpoints as desired. Click OK
to return to Measure Mode.
Please note: Changing Settings through the Setup menu are applied globally (see Cuvette Environment
on page 50) and will require a new LED Tuning when you enter Recording Mode.
