9.5. MENU ATC - Absolute Temperature Calibration
ATC serves to compensate a temperature difference that might occur
between circulator and a defined measuring point in the bath tank
because of physical properties.
Example:

Principle:
For ATC calibration, in steady state the bath temperature at the
location of the temperature sensor (CT) is determined at the
respective adjusted working temperature. This value is then set on
the circulator in the menu >ATCalibration< under menu item >Ctx<.
This can be a 1-point, 2-point or 3-point calibration.
