end values, unless an intermediate ‘spacer’ segment is used.

If segment start/end values are the same (Soak), advance to the
Soak Time
frame. If segment
start/end values are different (Ramp), advance to

.
Ramp Rate
Set the ramp rate.
The ramp rate is entered as the number of engineering units that change during the time period
(hours or minutes) configured in the
Ramp/Soak Time Units
frame,
Profile Control Page
.
Example – if a ramp of 10
°
F at 2
°
every minute is required, the ramp rate value entered is 2.0 (in
the minutes time base).
Ramp rates set excessively low over a wide range cannot be displayed properly at the
Current

(
Time Remaining
) frame. This display shows a maximum of 999.9 units of time.
The display is decremental when the time remaining is less than 999.9.
