4.1.2 Functionality of Temperature Control

• Sample surface temperature is the one which is regognized and control is

set to. Controller is optimizing itself to current operation and environmental

temperatures.

•

Sample surface temperature is kept constant to target value +/-0.02°C.

•

If instrument is operated in completely new conditions or target value is

changed remarkably, it can take up to 30mins until target value +/-0.30C is

reached. It is not an error of the instrument, it is more an indication that

optimization is in progress

•

Once optimization of control has been finished, the parameters are stored

once instrument is shut-down or temperature control is set to „OFF“
