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.
Start
Required temperature stabalization period operating undisturbed with the incubator door(s) closed.
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.
2
A display calibration adjustment must be entered to match the
display to the reference device. See next step.
