Titration sequence of SET
After the start, the activate pulse is outputted and the stir-
rer switched on.
The start delay time is waited off.
If conditioning is on, the sample solution is titrated until
the (first) EP is reached. The display shows then
drift OK 2.3 ul/min
or
SET pH conditioning
The vessel is now conditioned. The titration can be started
with <START>.
The sample identifications and the sample size are re-
quested.
The temperature is measured if a T sensor is connected.
Pause 1 is waited off, the start volume is dispensed and
pause 2 waited off.
The titration to EP1 then to EP2 is executed. If the extrac-
tion time is not yet over when EP1 has been reached, the
titration will only be terminated after the extraction time is
over.
The stirrer is switched off when there is no conditioning.
Calculations are carried out.
Data are outputted.
