How to select auto-tuning operation
Explanation
●
P.I.D value is set automatically.
●
When it is automatically set by auto-tuning,
the P.I.D value is stored so even if power is
switched off, there is no need to set it again.
●
During auto-tuning operation, the decimal
point on the right of the display will flash.
①
AT=1 (standard type)
②
AT=2 (low PV type)
Low PV type reduces overshoot when tuning.
* The value of P.I.D is set beforehand.
Please use this function only when control is
not optimum.
