Selecting the Time Stop Condition
The following instructions explain how to select Time as the stop condition for a task or a step of a task.
For information about using the data entry pad, see “Using the Data Entry Pad” on page 3-21.
From the Setup screen:
1. Touch
Stop Condition
.
The Setup: Stop Condition window opens.
2. Touch
Time
.
A data entry field appears, and
Time
changes to black.
3. Touch the data entry field.
A data entry pad appears.
4. Use the data entry pad to enter the desired number of minutes.
5. Touch
Enter
on the data entry pad.
The data entry pad closes, and the data entry field displays the number of minutes you entered.
6. Touch
Confirm
.
The Setup: Stop Condition window closes.
Exchange
The Exchange stop condition includes two values: the IC Volumes value and the EC Volumes value.
The IC Volumes and EC Volumes values are units of measure unique to the Quantum system.
IC Volumes reflects the IC circulation loop volume plus an approximated inlet line volume. EC
Volumes reflects the EC circulation loop volume plus an approximated inlet line volume.
1 IC Volume = the volume of fluid in the IC circulation loop + an approximated inlet line volume
(approximately 200 mL of fluid)
1 EC Volume = the volume of fluid in the EC circulation loop + an approximated inlet line volume
(approximately 300 mL of fluid)
For example, if you enter 1.5 IC Volumes, the system calculates, based on the IC circulation loop
volume, the amount of fluid needed to exchange the volume of fluid in the IC circulation loop 1 ½ times.
The system then adds fluid until it reaches the calculated amount and the task ends. The system also
determines the pump rates based on the values that you enter for both IC Volumes and EC Volumes, so
it always reaches the specified IC Volumes and EC Volumes at the same time. The following example
shows how this operator's manual denotes the Exchange stop condition:
Exchange (2.5 IC Volumes) (2.5 EC Volumes)
