2.6 Parameters, key <PARAM>
The key <PARAM> is used for the entry of values that
determine the titration sequence. Values marked with
"cond." are accessible during the conditioning. "**titr."
means that these values can be changed during the
titration. They influence the ongoing determination.
Other values can only be changed in the inactive state.
The display texts of the Titrino are shown to the left.
The values are the default values.

General titration parameters
Extraction time (-9999.. 9999 s)
for
- that evolve sample slowly
- work with KF oven
With positive extraction times, titration is performed
continuously during this time; with negative values no
titrant is added during the extraction time. The
extraction time can be aborted with <QUIT>.
Type of stop criteria (drift, time)
Titration stops if EP is and stop drift is reached. (1...999
µL/min)
Titration stops if there is no dosing during t(delay).
(0...99 s)
Switch off when the end point is reached and the set
time after the last dispensing has elapsed.
Stop volume (0...99.99 mL, OFF)
Safety stop, e.g. if no endpoint is found.
<CLEAR> sets "OFF".
Start volume (0.00…99.99 mL.)
Performed and inquired only in KFT mode.
Start volume is dispensed before titration start. In the
