•
The proportional band (P) is adjusted
as shown in the figure on the left.
To fine-tune a proportional band obtained using auto-tuning, or to
manually tune the proportional band:
• Work from larger to smaller numbers (wider to narrower)
• If cycling appears, that means that the proportional band is too
narrow.
• Proportional band tuning cannot cancel an offset.
