7.3 Endpoint titrations (SET)
7.3.1 Conditioning
Menu ▶ Parameters ▶ Conditioning
The conditions required for conditioning are defined under Conditioning.
Conditioning
If this parameter is switched on, 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 [START] has been pressed once more. Conditioning will
be carried out again automatically after the titration.
Selection on | off
Default value off
Start drift
Conditioning OK will be displayed as soon as this volume drift has been
reached and the titration can be started.
Range 1 ... 999 µL/min
Default value 20 µL/min
Drift correction
The endpoint volume can be corrected by taking the drift value into
account. For this, the volume drift is multiplied with the drift correction
time and this value is then subtracted from the endpoint volume. The drift
correction time is the time interval between the end of conditioning and
the end of the determination.
Selection auto | manual | off
Default value off
auto
The value of the current volume drift is applied automatically at the
start of the titration.
manual
If the volume drift is known throughout a prolonged period of time,
then this can be entered manually.
off
No drift correction takes place.
Drift value
This parameter is visible only when Drift correction = manual.
