Calibration
The Settings -> Calibration menu item enables the user to initiate a temperature calibration
process (see “Temperature Calibration Procedure” on page 10-3 ) for the built-in temperature
sensors and choose whether calibration should be accomplished manually or automatically:
• The Manual option allows for entering an absolute temperature directly, as measured - for
example, using an external reference sensor.

Calibration Prerequisites

Maintain the ambient conditions within the specified limits of the
incubator before launching calibration.
Varying ambient conditions may impact the result of the
calibration routine, which may lead to mis adjustment of the
controller and unreliable temperature control operation.
