900 Touch Control
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).
29.3.5 Conditioning
The conditions required for conditioning are defined under [Condition-
ing].
Conditioning
on | off (Default value: off)
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.
Selection auto | manual | off
Default value off
auto
The value of the current drift is automatically applied at the start of the
titration.
manual
If the drift is known throughout a longer period of time, this can be
entered manually.
off
No drift correction takes place.
Drift value
This parameter can only be edited with Drift correction = manual.
