Run time
Selects the run time (chromatographic analysis
time) between switching the injection valve to the
"INJECT" position and the start of a new injection
with the same or the next sample.
The minimum run time is 0.1 min. If 0.0 min is
entered the external injection start is activated.
The sample loop will only be filled and the injec-
tion started when a contact closure has been
made at the "EXTERNAL INJECT INPUT". The
run time will then be determined externally.

Time for event T1
Selects the time after which a signal in the form
of a contact closure will be produced at output
"T1".
The signal will only be produced if the selected
time is shorter or the same as the run time. If the
production of a signal is to be avoided for a
sample series then a time must be selected
which is longer than the run time.
