time that is suitable for the drift will be calculated automatically according
to the following equation:
Titrando, 855
Range
0.1 ... 999999 s
Default value 38.0 (slow), 26.0 (optimal), 21.0 (fast) s
Titrino
Range
0.1 ... 9999 s
Default value 38.0 (slow), 26.0 (optimal), 21.0 (fast) s
Dosing of increments
Note
The following parameters will be displayed only if the option User is
selected in the selection list Titration rate.
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 signal drift and a higher EP criterion at the same time.
Range 0 ... 9
Default value 2 (slow), 4 (optimal), 6 (fast)
Min. increment
This smallest permitted volume increment is added at the start of the titra-
tion 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;
otherwise 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
