signal drift 50 mV/min

equilibr.time 26 s

Dosing rate for volume increments (0.01...150 mL/min,
max.)
<CLEAR> 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
Drift criterion for measured value acquisition. (input
range depends on the measured quantity:
pH, U, Ipol: 0.5...999 mV/min, OFF
Upol: 0.05...99.9 µA/min, OFF)
<CLEAR> sets "OFF".
This type of measured value acquisition is often called
an equilibrium titration.
"OFF" means that the measured value is acquired after
an equilibration time. This may be useful for slow
titration reactions or when the response of the
electrode assembly is slow.
Waiting time for measured value acquisition. (0...9999 s,
OFF)
<CLEAR> sets "OFF".
If no new equilibration time has been entered, the
Titrino calculates an equilibration time appropriate to
the drift, see page 31. The measured value is acquired
as soon as the first criterion (drift or time) has been
met.
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.)
<CLEAR> sets "max.".
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
