Measuring point density
A small value means small volume increments, i.e. a high measuring point
density. The curve then shows all the finest details which also include noise;
this could cause unwanted equivalence points to be found. A larger value,
i.e. a smaller measuring point density, permits quicker titrations. If you are
using a dosing device with a small cylinder volume then a smaller measuring
point density value may be beneficial. However, you should also set a smaller
measured value drift and a higher EP criterion at the same time.
Range 1 ... 9
Default value 2 (slow), 4 (optimal), 6 (fast)
Min. increment
This smallest permitted volume increment is added at the start of the titration
and with steep curves in the region of the equivalence point. Very small
values should only be used if a low titrant consumption is expected; other-
wise unwanted equivalence points could be evaluated.
Range 0.1 ... 999.9 µL
Default value 10.0 (slow), 10.0 (optimal), 30.0 (fast) µL
Max. increment
A maximum volume increment should be selected when the titrant con-
sumption up to the equivalence point is expected to be very small, a start
volume is to be added until just before the equivalence point is reached or
if the change of direction in the potential jump region is very abrupt, as
otherwise it is easy to add too large a volume in the equivalence point region.
The value should not be less than 1/100 cylinder volume.

Default value off
Dosing rate
Speed at which the volume increments are added. The maximum dosing
rate depends on the cylinder volume of the exchange unit or dosing unit
used.
