4.2.4.6. Changing the properties of a step
The following properties of a defined step may be changed using the
flow evolution graph’s visual elements:
• Duration: change by dragging the duration marker along the X-axis.
Whenever the mouse pointer is located near to the duration marker, it
automatically changes to a horizontal double arrow pointer.
The duration marker is prevented from being dragged before the
step’s start time.
When the dragging operation ends, the modified step and the ones
following it are automatically arranged in the time considering the new
duration set.
Pressing the Esc (escape) key during a dragging operation will
automatically cancel it so that the step will not change any of its
properties.
The duration of a step must always be a multiple of the command
latency of the selected pump model so that only those multiple
values will be allowed.
• Start and end flow rates: change by dragging the start and end flow
markers along the Y-axis. Whenever the mouse pointer is located just
over the flow markers, it automatically changes to a vertical double arrow
pointer.
During the dragging operation, the new flow rate values are shown in the
status bar (see 4.2.4.3. ).
Both the start and end flow markers are prevented from being
dragged out of the method’s flow range (see 4.2.3).
Whenever the dragging operation ends, the modified step is redrawn to
show the new expected flow rates and the corresponding flow evolution
line.
If the end flow of a step is changed and the following step was linked to
this step, the linked step will be also updated automatically (start flow
and flow evolution line).
• Step linkage property: change by checking / unchecking the menu
option Link to previous step, available in the contextual menu of the
step block.
