All T/C CO
2
cells are calibrated at the factory at 37°C, high humidity, and
10% CO
2
. Therefore, if a temperature setpoint of 37°C has been entered,
the humidity pan has been filled and the CO
2
control is to run between 0-
10% with a T/C CO
2
sensor, the CO
2
setpoint may be entered
immediately. Otherwise, it is important to allow the unit 12 hours to
stabilize at the temperature setpoint before entering the CO
2
setpoint.
Both models of the incubator have a CO
2
setpoint range of 0.0% to
20.0%. The incubator is shipped from the factory with a CO
2
setpoint of
0.0%. At this setting, all CO
2
control and alarms are turned off. To
change the CO
2
setpoint:
1. Press the MODE key until the SET indicator lights.
2. Press the right arrow until “CO2 XX.X” is displayed in the message
display.
3. Press the up/down arrows until the desired CO
2
setpoint is displayed.
4. Press ENTER to save the setpoint.
5. Press the MODE key until the RUN indicator lights to go to RUN
mode or press the right/left arrow keys to go to next/previous
parameter.
