Dispense 2.0 mL with a 5 minute pause between dispenses. In addition, after each dispense, a volume of 0.25
mL is sucked back to prevent dripping. Also, 30 seconds before the end of the pause interval, a beep is
sounded to alert the operator to prepare for the next dispense.
Starting with the second dispense, 0.25 is added to the volume dispensed to compensate for the sucked back
volume of the previous dispense. By changing the last Phase to a [LP:nn] function, the total number of
dispenses can be set.
When entering a function with associated data, such as with the ‘Pause’ in Phase 5, or the ‘Loop’ in Phase 6,
the function is entered in 2 steps. First select the function and store it. Then enter the associated data.
