900 Touch Control
Input range 0.00000 - 9999.99 mL
Default value 100,000 mL
Selection off
Stop time
The titration is stopped when the specified time has elapsed following the
termination of the start conditions.
Input range 1 - 999999 s
Selection off
Default value off
Filling rate
Rate at which the dosing cylinder is filled.
Input range 0.01 - 166.00 mL/min
Selection maximum
Default value maximum
maximum
The maximum filling rate depends on the cylinder volume (see Chapter
32, page 488).
29.4.5 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
Conditioning OK will be displayed as soon as this drift has been reached
and the titration can be started.
Input 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 drift is multiplied with the drift correction time and
this value is then subtracted from the endpoint volume. The drift correc-
tion time is the time interval between the end of conditioning and the end
of the determination.
