8.3 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the
proportional band during the PD action.
Since the corrected value is internally memorized, it is not necessary to perform the auto-reset again as
long as the process is the same.
However, when the proportional band is set to 0, the corrected value is cleared.
