Rate Ramp Type
Each ramp segment's TIME specifies the rate at which the profiler output will reach the next soak segment,
where the rate is specified by the prompts TIME/TIME UNITS. The ramp segment's VALUE prompt
is not used.

Segment #1

ATTENTION
Rate ramp type's TIME prompt is in engineering units of the PV, not in time units (seconds, minutes, or hours).

Ramp Type = Rate
Features of t h is ramp type
* First and l a st segments must be soaks
* No consecutiv e ramps or soaks
Ramp segment s
Time = rate at which next soak Value will be reached, in PV units/Time Unit s .
Example: Time = 3. Time Units = Seconds. PV uni ts = degrees F.
Therefore, profile will ramp to next soak Value at 3 degrees F per second
Value = not used with ramp segments
