5) Temperature Stabilization
The incubator air temperature must stabilize in order to perform an accurate calibration.
•
Allow the incubator to operate undisturbed with the doors shut for at least 8 hours when
first putting the unit into operation in a new environment.
•
To be considered stabilized, the incubator chamber must operate at your calibration
temperature for at least 1 hour with no fluctuations of ±0.1°C or greater.

Suggested Temperature Calibration
1
Once the incubator temperature has stabilized, compare the
reference device and incubator temperature display readings.
•
If the readings are the same, or the difference between the
two falls within the acceptable range of your protocol, the
display is accurately showing the incubator air
temperature. The Temperature Calibration procedure is
now complete .

•
If a difference falls outside of your protocol range, advance
to step 2.
