4.3.3 System functions
Start/stop hardware and record baseline
SYSTEM / Control / Startup hardware (Measure Baseline)
Starting the hardware at the 790 Personal IC includes sending of Sys-
tem startup values , starting of the high-pressure pump and (if present)
starting of the peristaltic pump.
At the same time, the
recording of the measurement signal using
the method defined for the system is started. Independently of the set
chromatogram Duration , the measurement signal is recorded until a
new determination is started. Alternatively the baseline recording can
be stopped by clicking the icon of the chromatogram window. In
this case, the user is asked if the recorded baseline should be saved or
not.
SYSTEM / Control / Shutdown hardware
High-pressure pump and (if present) peristaltic pump at the 790 Per-
sonal IC are immediately stopped. A running determination and an ac-
tive sample queue are also stopped.
Start/stop determinations
SYSTEM / Control / Start determination
Start determination using the settings of the selected system. At this
start command, the System startup values are set at the 790 Personal IC.
The high-pressure pump and the peristaltic pump are started if they are
not already running. The time program is started immediately; the data
recording is started after switching the injection valve to the "Inject" po-
sition.
At each start of a determination, the Edit sample description window is
opened automatically. This window can be used for entering informa-
tion concerning the sample:
