Annealing Control


Annealing Control

This software communicates with the Eurotherm 3508 PID controller used for reading the temperature of the sample and regulation of the annealing process. It contains only the frequently used functions while for advanced operations Eurotherm iTools software is used.

The graphs show the evolution of the
  • annealing Current (blue line),
  • desired temperature (Setpoint; red line), and
  • current Temperature (white line)
in the time interval defined by the View last selector.

Moreover, you can easily Change units (°C/K) and Set the Preset setpoins in order to avoid using the physical arrow buttons on the device in the experimental rack.

The software also shows the position of the KEEP TEMPERATURE/SET CURRENT MANUALLY switch and of the Knob of the CURRENT LIMIT on the device defining the maximum allowed annealing current.

Last but not least, you can observe the annealing/cooling Rate and set the software to attempt to Keep rate below the set value. An indicator shows at every moment if the current is Limited by:
  • the knob (i.e. PID regulation loop not synchronized, setpoint temperature not reached),
  • the PID regulator (loop synchronized, the regulator is trying to keep the setpoint temperature although oscillations may appear), o
  • the software (the maximum set by the knob is respected but it might be further decreased in order to limit the average rate below the set value, i.e. anneal the sample slower that the knob limit would allow).
