5 ) Heat up and stabilization period : The oven temperature must be stable at temperature in order to
perform an accurate calibration. The temperature is considered stabilized when the oven chamber has
operated at your calibration temperature for at least 30 minutes with no fluctuations greater than ±0.2°C .

Suggested Calibration Procedure
1
Once the chamber has stabilized, compare the reference
temperature device and chamber temperature display readings.
a. 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 chamber
temperature. The Temperature Calibration procedure
is now complete .
-Or-
b. See Step 2 if a difference falls outside the acceptable
range of your protocol.
