Additional Function
2.4
Auto Tuning is provide the best value for P.I.D Gain after calculation with
considering treat environment automatically, so that user can experiment
more accuracy and quickly.
Calculated Gain value is saved automatically, if user wish to same
experiment once again, the user need only tuning once.
Auto Tuning is only available during RUN session.
· Fix control mode
· Start with Auto-Tuning message.
*After the Auto-Tuning, the equipment will operate with set temperature.
/ During Auto-Tuning, due to calculate, in order to reach set
temperature Heater gives 100% output, so temperature go
higher than set value
*In case stop Auto-Tuning, apply Shift and RUN/STOP for 2 seconds at the
same time.
