3.1.7 Programming Operation
Operation with a program for isocratic mode is explained here.
As an example: upper pressure limit at 20.0 MPa, lower
pressure limit at 0 MPa, and flow rate is1.0 ml/min at 0 minute of
analysis time. Output pulse signals by Event 1 to 4.
Change the flow rate to 0.5 ml/min by 10 minutes of analysis
time.
The parameters in the table below are an example of input.
