3.2.4 Hardware start/stop and baseline recording
Start
Starting the hardware (by selecting
SYSTEM / Control / Startup hard-
ware ) on the 861 Advanced Compact IC includes sending the System
startup values defined for the system, starting the high-pressure pump,
(if present) the peristaltic pump and (if present and activated under Con-
figuration , see Section 3.3.1) the 853.
At the same time recording the measuring signal is started, using
the method defined for the system. The measuring signal is recorded
regardless of the set chromatogram Duration , until either data recording
is stopped with SYSTEM / Control / Stop data acquisition or a new determi-
nation is started. Alternatively data recording can also be stopped by
clicking on in the chromatogram window. In this case the user will
be asked if the recorded baseline is to be saved or not.
Stop
If
SYSTEM / Control / Shutdown hardware is selected then the high-pres-
sure pump and (if present) peristaltic pump at the 861 Advanced Com-
pact IC are stopped immediately. The current determination and pro-
cessing an active sample table are also stopped. In addition the Re-
mote output lines are set to the values defined under Hardware / Remote
lines after power on .
3.2.5 Determination start/stop
Start
By selecting
SYSTEM / Control / Start determination
a determination is
started using the settings of the selected system. At the start the
startup values defined under System startup values will be set at the 861
Advanced Compact IC. If they are not already in operation the high-
pressure and peristaltic pumps will be started. Depending on the set
Start mode, the time program and data recording will either start imme-
diately (for Start with determination ) or only when the injection valve is
switched to the "INJECT" position (for Start with inject ).
Stop
If
SYSTEM / Control / Stop determination is selected then the current de-
termination is stopped. Data recording and the time program are
stopped immediately. The recorded chromatogram is saved automati-
cally, if the option Save chromatogram after the run has been switched on
under Passport / Processing .
Alternatively the determination can also be stopped by clicking on in
the chromatogram window. In this case the user will always be asked if
the recorded baseline is to be saved or not.
