ATC is used to compensate for a temperature difference between the
circulator and a defined measuring point in the bath tank that may
develop for physical reasons.
ATC internal
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 > CTEMP X <.
This can be a 1-point, 2-point or 3-point calibration.
