2.9 Manual Tuning
In certain applications, using Auto-Tuning may be inadequate for the control requirement, or, the process
moves too slowly to Auto-tune accurately.
If this is the case, the user can try manual tuning.
If the control performance by using Auto-Tuning is still unsatisfactory, the following guidelines can be applied
for further adjustment of PID values.
Proportional Band ( PB )
High overshoot or Oscillations
Integral Time ( TI )
Instability or Oscillations
Derivative Time ( TD )
Slow Response or Oscillations
