Stop time

Absolute titration duration

1…9999 s | off

The titration will be terminated when the defined stop time

has elapsed.

Termination when measuring point list is full

on | off

If 'on' is selected the titration will be terminated when the
measuring point list is full (1000 measuring points).

When 1000 measuring points have been reached with 'off'
the titration will be continued but no further measuring

points will be recorded.

8.6.2 Custom adjustments

Custom adjustments allow the control parameters of the titration to be finely

tuned. Starting with a set of parameters (fine, medium, coarse) after press-

ing the softkey [User defin.] under 'Adjustments' on the parameter
page the individual parameters can be altered in the dialog window 'Custom

adjustments'.

Measurement range for controlled titration

for KFT_IPOL:

1…100.0…2000 mV | off

for KFT_UPOL:

0.1…10.0…200.0 µA | off

The control range defines the measurement range in

which controlled titration is carried out before the given

endpoint. Outside this range addition is made at the

maximum dosing rate. For KF titrations the use of the

proven standard settings is recommended.

If the control range is switched off controlled addition

will be made throughout the whole titration.
