■When the auto tuning is started with the temperature process value (PV) that is within the
stable judgment width (1 ()) after the mode has shifted from the setting mode to the
operation mode
Until the temperature process value (PV) goes outside the stable judgment width (1 ()), the data measured after the mode
has been shifted to the operation mode ('Setting/operation mode command' (Y1) is turned from OFF to ON) can be used.
Thus, the simultaneous temperature rise parameter can be calculated by the auto tuning.
