9.5.2. Selftuning
When performing a selftuning for the controlled system (temperature
application system), the control parameters Xp, Tn and Tv are
automatically determined and stored.
Possible parameters:
off - no
selftuning
The control parameters ascertained during the last identification are
used for control purposes.
once - single
selftuning (factory setting)
The instrument performs a single selftuning of the controlled system
after each start with the
key or after receiving a start
command via the interface.
always - continual
selftuning
The instrument performs a selftuning of the controlled system
whenever a new setpoint is to be reached.
Use this setting only when the temperature application system
changes permanently.
9.5.3. Dynamik intern
This parameter affects the temperature sequence only in case of internal
control.

Factory setting: APER (aperiodic)
Possible parameters:
normal Allows for reaching the setpoint faster – with
setpoint change or ramp function – but
overshooting of up to 5 % is possible.
aperio Ramp function: the increase of temperature
occurs temporally offset and achieves the target
temperature without overshooting.
Setpoint change: The temperature increases at
the same rate, the target temperature is achieved
without overshooting.
With both settings constant temperature is achieved
after approximately the same time.
