Adjusting the Proportional Band

When fine-tuning a proportional band obtained from auto-tuning, or when adjusting the

proportional band manually, note the following points.

Always adjust downwards from a larger value to a smaller value.

If oscillations appear, it means that the PB setting is too small.

- Adjusting the proportional band will not eliminate the offset. (Adjusting the Integral

Time (TI) and Manual Reset (MR) parameters may however eliminate the offset.)
