Move to the next CO
2
sub-
menu item with (⇩) key or one step up with (⇧) key.
CO
2
flow rate is shown (it cannot be adjusted):
It shows the amount of CO
2
gas put into the system while regulating. The volume is shown
in liters/hour. It usually will fluctuate along with the CO
2
regulation.
Press the
(⇩) key
to move to the next item in the CO
2
sub-menu. CO
2
internal pressure
rate is shown (it cannot be adjusted on the incubator. It is adjusted on the external gas
regulator):
The value is in bar and it must be 0.4
–
0.6 bar (5.80
–
8.70 PSI) at all times.

how to calibrate CO
2
:
CO
2
gas concertation has to be measured with a suitable and calibrated device. The real
CO
2
concertation has been determined to be 5.4% on the gas sample port.
Locate “CO2 CAL” in the CO
2
sub-menu and press the SP key. The display will show:
Adjust the calibration to the desired level by pressing
(⇧) or (⇩) keys. In this case, we
want to adjust to 5.4%. Press
(⇧) key
4 times. The display will show 5.0, 5.1, 5.2, 5.3 and
5.4. When CO
2
equals measured CO
2,
let go of the SP key. The value is stored and the CO
2
sensor calibration has been modified.
Pure CO
2
100% gas recovery till 5% is less than 4 minutes.
Calibration is done by adjusting the CO
2
level according to a measurement
taken from the gas sampling outlet, using a precision CO
2
measurement device
only.
