between two lines.
The complete program is transferred or “uploaded” to the pump when you
start a run.
All time programs are displayed in a spreadsheet similar to the one
shown below. Although the information in the fields will vary, the
spreadsheets always support certain basic features.

configuration which can be setup for all pumps independently.
