d)
Enter the purge screen of the micro pump, set the flow rate to 0.0 ml/min and select
channel A. The LED of channel A should be illuminated
e)
Measure the flow rate for one minute. The flow rate should be greater than
0.15 mL/min
f)
Repeat steps d) – e) for solvent channels B, C and D.
g)
Switch off the pump. The flow should stop immediately.
