Changing Parameters During a Run

While a run is in progress, run parameters (speed, time, temperature, and acceleration or
deceleration rate) can be altered without stopping the run. Run duration can also be changed from
continuous to a specified time period, or from a specified time period to continuous.
NOTE
The deceleration rate cannot be changed after deceleration starts.
Use the program keys as described under Entering Run Parameters, above, to change parameters.
Parameter changes made during a run must be verified by pressing the
