Temp. Controller AVS46 (LTF)

If the tab Modify Devices is selected a list of the available devices will appear. The Temperature Controller device can be selected and a button Modify will be available.

By hitting the button Modify, a first dialog appears giving the possibility to change the temperature setpoint (Modify Temperature).
Note that the "Cryostat Mode" has to reflect the actual mode of operation of the dilution fridge. The setting of the mode (including loading the PID table and the allowed limits of the temperature range of the mode) is done by the Instrument Scientist.

First dialog to modify the temperature setpoints. Note also the button to reset the calculation of the average temperature.
When modifying the temperature setpoint a second dialog will appear. The first column shows the currently set values and in the second column the new values can be edited. The parameters are: setpoint; temperature range and time for the stability criterium for the first control step (without integral part); temperature range and time for the stability criterium for the second control step (with integral part). The values can be modified in the table and changes will be applied by pressing the button OK.
