CO2 Incubators > Seating IR Sensor  »   What are the symptoms?

If the CO2 display reads 20.0% or a value which has been set using the panel calibration and does not change IR without regard as to how much CO2 is actually in the chamber. Note: If the display value is below the set point, the unit will continue to inject CO2. If the display value is above the set point, the unit will not inject CO2 at all.
