By executing AT (auto-tuning), the most suitable PID parameters can be set.
The AT function allows PID parameter calculation by recognizing the character-
istics of the object from the waveform (amplitude and period) to be generated
when ON/OFF control is executed (refer to the following diagram). The PID pa-
rameters obtained will be refreshed automatically, and after completion of auto-
tuning, the Temperature Control Unit will start operating using the parameters.
