Max. waiting time

If signal drift has been switched off or has not yet been reached, then the
measured value will be accepted when the maximum waiting time has
elapsed. If the waiting time has not been newly entered then a waiting
time that is suitable for the drift will be calculated automatically according
to the following equation:

Titrando, 855
Input range

0.1 - 999999 s

Default value

38.0 (slow), 26.0 (optimal), 21.0 (fast) s

Titrino
Input 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 user option 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.

Input 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.

Input range

0.1 - 999.9 µL

Default value

10.0 (slow), 10.0 (optimal), 30.0 (fast) µL
