• G.SOAK at end of segment
PV and SP are compared at the end of the segment. The operation in that segment
ends when the absolute value continues beyond the G.SOAK time and becomes nar-
rower than G.SOAK width.
A G.SOAK wait state continues until these conditions are met which is announced by
the flashing of the linear LED at the center of the profile display.
The operating condition is the same as HOLD at the end of a segment (time = set seg-
ment time).

• G.SOAK for entire segment
PV and SP are compared at across the entire segment. The operation in that segment
continues when the absolute value continues beyond the G.SOAK time and becomes
narrower than G.SOAK width.
A G.SOAK wait state continues until these conditions are met which is announced by
the flashing of the linear LED at the left and the center of the profile display.
The operating condition is the same as HOLD at the continued time.
A PV correction value can be set for each segment. PV is PV input value plus PV bias
and PV shift. Note, however, that in the READY mode and the constant value control
mode, PV bias but not PV shift is added to the PV input value.
The setting in the previous segment continues when PV shift is set to "-----"(nothing).
