The internal and external control parameters can be adjusted in the submenu <Control performance>.
For internal control, the control dynamic can be set to either Standard or Aperiodic:
• With Aperiodic the temperature increase is temporally offset, so that the actual temperature doesn’t overshoot
• With Standard the temperature increase is faster, but the actual temperature can overshoot by up to 5%
Proportional range Xp
The proportional range Xp is the temperature range between the setpoint value and the actual value, in which the heating capacity can be adjusted from 100% to 0%. The value for Xp can be selected between 0 K and 10 K.
Integral controller Tn
The integral controller Tn is indicated in seconds. It reduces the difference between the setpoint value and the actual value caused by the Xp component, and keeps to the setpoint value.
Differential controller Tv
The differential controller Tv is specified in seconds. It shortens the regulation time.
CoSpeed factor
The CoSpeed factor affects the temperature sequence when used with external control. It directly affects Xpu and causes more aggressive temperature control.
Proportional range Xpu
The proportional range Xpu plays a role in external control. It corresponds with the proportional range Xp for internal control.

8.11 Adjusting the temperature sensor (ATC)
For physical reasons, there can be a temperature difference in the bath tank between the temperature sensor and a defined, more remote point within the bath fluid volume. As a result, the measured temperature deviates slightly from the actual bath temperature. Adjustment of the temperature sensor can increase accuracy of the temperature control application.
The adjustment of a temperature sensor requires the determination of the temperature difference between the temperature sensor and the reference thermometer. Three adjustment options are available:
• 1-point adjustment: When a sample is tempered to a certain setpoint. The
adjustment curve is displaced parallel to the original curve by the reference amount.
• 2-point adjustment: When the temperature is controlled between two
setpoints. The slope of the temperature curve is adjusted between two points.
• 3-point adjustment: When temperature is controlled within a temperature
range. This results in an arched temperature curve.
