Stop conditions
The conditions for canceling the titration are defined under [Stop condi-
tions], if this does not occur automatically. This could be the case when
the endpoint set is not reached or if the stop criterion (see "Stop crite-
rion", page 345) is not fulfilled.
Stop time
The titration is stopped when the specified time has elapsed since the start
of the titration.
Input range

29.6.4
Conditioning
The conditions required for conditioning are defined under [Condition-
ing].
Conditioning
on | off (Default value: on)
If this parameter is activated, then the first time the titration is started the
working medium will be titrated to the endpoint with the specified control
parameters. The status is kept stable. The actual method run does not
begin until [
] has been pressed once more.
Start drift
If the measured drift is smaller than this value for a certain time (so-called
stabilizing time), Conditioning OK is displayed and the titration can be
started. The stabilizing time is defined in the dialog Conditioning / Con-
ditioning options.
Input range
1 - 999 µg/min
Default value
20 µg/min
Drift correction
The endpoint amount can be corrected taking the drift value into account.
For this, the drift is multiplied with the drift correction time and this value
is then subtracted from the endpoint amount. The drift correction time is
the time interval between the end of conditioning and the end of the
determination.
