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.
