After matching the display to the reference device, wait
5 seconds.
•
The gas display will cease flashing and store
the corrected chamber display value.
•
The incubator will now begin injecting CO
2
or
allowing the current concentration to decay in
order to achieve the setpoint with the
corrected display value.
Decaying to Setpoint
6
Allow the incubator to sit for at least 1 hour undisturbed
to stabilize
after the incubator has achieved the
corrected gas setpoint
.
•
Failure to wait until the incubator is fully
stabilized will result in an inaccurate reading.
