Priming
Priming is used to prepare the entire system. This
preparation procedure includes the distillation and
titration with a clean and empty sample tube, as
well as the dosing of chemicals. It is recommended
to perform a priming at least once a day, before
starting analysis. The priming procedure is similar to
a sample determination method and can be modi-
fied.
Priming Parameters
Select Yes for “Preheating before priming” if prior to
the priming procedure a preheating procedure shall
be performed.
Set the number of “Priming runs”.
Set “Priming cycle” to “Via sampler”, if the priming
procedure should be performed via a present
sampler. (Only visible if a sampler has been config-
ured under “Settings”.)
The other parameter sets Distillation Parameters,
Titration Parameters, and Aspiration Param-
eters are just the same like within a method. A
detailed explanation can be found in the section
“6.8.1 Method”.
Press START to start the priming procedure.
Press FACTORY DEFAULTS to reset the settings
of this screen.
NOTE
If only one priming cycle is selected and no aspira-
tion, no aspiration will be done at all.
If more than one priming cycle is selected and no
aspiration, the sample tube and the receiving vessel
will be aspirated between the single priming cycles,
but not after the last cycle has been performed –
instead the system will be stopped after the last
run.
