Discontinuation: full measuring point list
on | off
If 'on' is selected, titration is discontinued when the meas-
uring point list is full (1000 measuring points).
At 'off', titration continues after 1000 measuring points, but
no further measuring points are recorded.
8.2.2 User adjustments
User adjustments allow fine adjustment of the pre-set titration parameters.
Starting from one of the sets of parameters (slow, medium, fast) go to 'Ad-
justment
' in the method editor and press the [Custom adjust] softkey
to change the individual parameters in the ‘Custom adjustments’ dialogue
window.

Meas.pt.density
Meas. pt. density
0…4…9
The measuring point density is a measure of how often
the measuring points are determined during the titration.
This parameter has a direct impact on the size of the
variable volume steps. A small measuring point density
value results in small volume steps, i.e. lots of individual
measuring points. A large value results in big volume
steps, i.e. fewer measuring points.
Min.increment
Minimum volume increment
0,1…10…999,99 µL
To avoid excessively small volume steps with dynami-
cally controlled titrations (and hence "endless" waits),
the minimum volume increment can be pre-set. Caution
should be exercised when changing this parameter, as
excessively large volume steps can adversely affect the
accuracy of the results.
Titr. rate
Titration rate
0,01…150 mL/Min | max
The titration rate has a direct impact on the dosing rate of
the volume increments. The maximum value depends on
the buret cylinder size.
