7. The oven temperature must be stable in order to perform an accurate calibration. The temperature is
considered stabilized when the oven chamber has operated with the door closed at your calibration
temperature for at least one hour with no fluctuations greater than the specified stability of the oven (see
page 41).

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

The display requires a calibration adjustment.
•
The difference between the reference device and the display is
an offset value .
