Dynamic Control - Xylem TitroLine 7000 Manual De Instrucciones

After the start of titration, it makes frequently sense to have the sample stirred over a defined period of time,
for instance, to allow for the sample to be dissolved. The waiting time to be observed prior to the first addition
of titration solution can be set using the <Initial waiting time> item. The initial waiting time can be set between
0 and 999 seconds (Fig. 127).

4.6.5.2 Dynamic control

If dynamic control was selected, one has a selection of 3 different stages («steep», «average» and «flat»)
or «user-defined» dynamic parameters(Fig. 128).
Fig. 128
On the stages, both the dynamic parameters and the minimum and maximum step sizes are defaulted
Dynamic parameters
