Maximum dosing rate (0.01...150 mL/min, max.)
sets "max.".
This parameter determines primarily the addition rate
outside the control range, see page 21.
The maximum rate depends on the Exchange Unit:
Exchange Unit max. rate
5 mL 15 mL/min
10 mL 30 mL/min
20 mL 60 mL/min
50 mL 150 mL/min
Minimum volume increment (0.1...9.9 µL, min.)
sets "min.".
This parameter determines the addition rate at the start
and the end of the titration, see also page 21.
This parameter influences the titration speed and
therefore its accuracy very strongly: A smaller
"min.volume incr." results in a slower titration.
Type of stop criteria (drift, time)
Titration stops, if EP and stop drift are reached
(1...999 µL/min)
Titration stops if there is no dosing during t(delay)
(0...999 s, INF)
sets "INF".
Switch off when EP is reached and the set time after
the last dosing has elapsed.
If t(delay) is "INF"
Stop after a time (0...999999 s, OFF)
sets "OFF".
Stop after the set time after start of titration. "OFF"
means no stop, i.e. titration for an "infinitely" long time.

Titration parameters
Direction is set automatically (+, –, auto)
auto: The direction is set automatically by the Titrino.
+: Direction of higher voltage (more "positive"),
larger currents.
– : Direction of lower voltage, smaller currents.
Pause 1 (0...999999 s)
Waiting time before start volume, e.g. for equilibration
of the electrode after start. The waiting time can be
aborted with .
