“Ramping” protects a process from rapid changes in the setpoint and the resulting thermal shock, as the
controller tries to force the process variable to follow. Athena temperature controllers have the facility to
used with this feature to ensure the process closely follows the rate ramp. When the setpoint reaches the
top of the ramp, a “soak period” begins where the setpoint is maintained at this value.
Single Setpoint Ramp Time
This selection will cause the controller to ‘ramp’ the process from the starting point (current process value)
to the setpoint in the time specified. This ramp will take place at startup when selected from the Ramp/Soak
menu. The setpoint must be at least ±0.2% of sensor span for the ramp to be employed.
