min.rate 25.0 ul/min
**titr.
Minimum dosing rate (0.01...9999 uL/min)
This parameter determines the addition rate in the
range of the control point.
Rule of thumb for "min.rate" in uL/min = (expected rate
of the reaction in uL/min)/10.

Titration parameters
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
Waiting time after start volume (0...999 999 s)
Waiting time, e.g. for equilibration of the electrode after
start or reaction time after dosing of a start volume. The
waiting time can be aborted with .
Start time for data acquisition (0...999 999 s)
Measured values will be acquired only after the start
time has elapsed.
Start measured value for data acquisition (input range
depends on the measured quantity:
pH: 0...±20.00, OFF
U, Ipol: 0...±2000 mV, OFF
Upol: 0...±200.0 uA, OFF)
sets "OFF".
Measured values will be acquired only after start of
measured value has been reached.
