Proportional coecient of PID (Kp 1):

Integral time of PID (Ti 1):

Differential time of PID (Td 1):

The proportional coecient Kp is the controller ampliﬁcation and determines how strongly the control deviation (the difference between the target temperature and actual temperature) directly affects the control variable (ontime of the heater)� Kp values that are too large can lead to the controller overshooting�

The integral time Ti (s) is the correction time and determines how strongly the duration of the control deviation affects the control variable� Ti compensates an existing control deviation� A high Ti means a smaller and slower effect on the control variable� Ti values that are too small can lead to instability of the controller�

The differential time Td (s) is the derivative time and determines how strongly the rate of change of the control deviation affects the control variable� Td compensates for rapid control deviations� A high Td means a smaller and slower effect on the control variable� Td values that are too small can lead to instability of the controller�

•

External and internal temperature control (ET) (heating):

ET 0: internal temperature control ET 1: external temperature control

If the external temperature control (ET 1) is selected, the following items EuT 2 (sampling time), Kp 2, Ti 2, Td 2, Df t (maximum temperature difference between internal and external temperature) and FAST could be set� Otherwise they are not displayed in the menu list�

The sampling time EuT 2 (s) is the interval over which the external control deviation and the respective control variable (dependent on Kp 2, Ti 2, Td 2, Df t and FAST) is determined� EuT 2 must be adjusted to match the response characteristic (total of all time constants) of the external closed loop controlled system, so that the control variable can deliver a uniform and measurable change in the control deviation� EuT 2 values that are too small or too large can lead to instability of the controller�

Dynamics of the external PID temperature control (FAST):

FAST=0: accurate, without overshoot FAST=1: fast, with overshoot

•

Alarm and key tone (BEEP):

BEEP 0: no alarm and key tone BEEP 1: alarm and key tone is activated

•

Calibration and adjustment (CALI):

CALI 0: Reset calibration CALI 2: 2-point calibration CALI 3: 3-point calibration

Example: 2-point calibration:

Dip the temperature sensor of the reference measuring device into the bath ﬂuid:

- If ET 0: into the internal bath (open the lid (2))

- If ET 1: at the same position as the external Pt100 temperature sensor (13)�

If ET 0: adjustment of the internal temperature measurement� If ET 1: adjustment of the external temperature measurement�

Set the ﬁrst point temperature (e�g� 80 °C)� Conﬁrm the setting by pressing the right knob (J)�
