5.3.4 Program Mode’s Pump Table
The Pump Table displays the contents of all pump steps within the method. This table can be viewed by
pressing the Pump instrument key while in Program mode or by pressing the Pump softkey on the Method
List screen. Each pump step contains a buffer composition, a duration, and a flow rate. Table 16 describes
how to program the Pump Table.

Program Mode’s Pump Table
Reference Description
Pump Table: Each step in a method is shown in a scrolling list
format. The selected step is shown with an arrow (>) pointing
to the step. Use the Prev and Next keys to move the selection
up and down the list. When the selected step is already pro-
grammed, the softkeys are as shown in the top picture and
when the selected step is not already programmed the softkeys
are as shown in the bottom picture.
The table consists of 5 columns: the step number, the duration,
the buffer, the flow rate, and the cumulative method duration
including the step. Up to 50 steps can be programmed in a
method and the duration units will be either time (minutes) or
volume (ml), depending upon the choice made when the
method was created.
•
Insert: This places a new step into the method, which will
have the same step number as the current selected step.
The currently selected step and all subsequent steps will
have their step number increased by one.
• Edit: This allows the contents of the selected step to be
changed.
• Delete: This removes the selected step from the table. The
step cannot be retrieved.
• Add: This allows a new step to be added to the end of the
table.
• OK: This indicates that the table is complete and returns to
the Method List.
Note: To program the Fraction Collector Table or the Alarm
Table without returning to the Method List press the Collector
and Alarm keys respectively while viewing the Pump Table.
