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 [FUN LOP nn] function, the total
number of dispenses can be set.
