Acceleration and Deceleration Times
Overview
Programmable Acceleration and Deceleration times control how rapidly the
pacing rate changes in response to increased or decreased physical activity.
Acceleration Operation
Acceleration time is the time required to achieve approximately 90% of the
difference between the current rate and a higher steady-state rate consistent
with the current level of activity.
The illustration below shows a graphic representation of the Acceleration
curves at the onset of strenuous exercise.
