stop drift 20 ul/min

t(delay) 10 s
**titr.
stop time OFF s
**titr.
Type of stop criteria (drift, time)
Titration stops if EP and stop drift are reached (1...999
uL/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 "INF" = an inquiry for the stop time appears.
Stop after a time (0...999 999 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.
Waiting time before start volume (0..999 999 s)
Waiting time, e.g. for equilibration of the electrode after
start. The waiting time can be aborted with .
Type of start volume (OFF, abs., rel.)
"OFF": start volume switched off
"abs.": absolute start volume in mL
"rel.": relative start volume to sample size.
If "abs." is set:
Absolute start volume (0...999.99 mL)
If "rel." is set:
Factor for relative start volume (0...±999 999).
Calculated as: start V in mL = factor * sample size
Dosing rate for start volume (0.01...150 mL/min, max.)
sets "max.".
The maximum rate depends on the Exchange Unit:
Exchange Unit max.
5 mL 15 mL/min
10 mL 30 mL/min
20 mL 60 mL/min
50 mL 150 mL/min
