'OUt.n': Set TTL Output Pin
n
Set ‘Program Output’ TTL I/O output (pin 5) to level ‘n’. If ‘n’ = 0, the output pin will be set low. If
‘n’ = 1, the output pin will be set high.

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.
