Initial Hold Time (min) – This is the time in minutes the initial flow is maintained. The
initial hold time can be programmed from 0.0 to 999.9 minutes.
Ramp Rate ((ml/min)/min) – This is the programmed rate the flow will increase after
the initial hold time. The ramp rate can be programmed from 1 to 500 in 1 ml/min
increments.
Final Flow (ml/min) – This is the final flow rate. The final flow can be programmed
from 0 to 250 in 1 ml/min increments.
Final Hold Time (min) – The final hold time is not an entered value. Final hold time is
the calculated difference of the final bake time taken from the sum of the initial time and
the ramping time needed to achieve the final flow rate.
Example: Total Bake Time = 10 minutes
Initial Flow = 40ml/min
Initial Hold Time = 2 minutes
Ramp Rate = 40ml/min
Final Flow = 240ml/min
Final Hold time = 3 minutes
Explanation: Since it takes 5 minutes to ramp from 40ml/min to 240ml/min at a
rate of 40ml/min. The final hold time is calculated to be 3 minutes.
10 minutes – (2 minutes + 5 minutes) = 3 minutes
