The parameters for Control device, Sensor, Dosing device and
Stirrer are described in Section 4.1.5.
Titration sequence for DET and MET
Start of titration
command
(Switch on stirrer) The stirrer is switched on after the start.
Measure initial
measured value
The initial measured value is measured.
(Start conditions:
start volume
start meas. value
start slope
pause)
The start volume is added with the start conditions
being processed in succession. No measuring
points are entered in the list of measuring points.
The pause interval is allowed to elapse.
Titration:
add increments
accept measured
values
Volume increments are added during the titration
and a measuring point is entered on the list of
measuring points after each increment. Measured
value acceptance is either drift-controlled (equilib-
rium titration) or a fixed waiting time is allowed to
elapse. The first criterion to be fulfilled applies.
Stop conditions The first criterion to be fulfilled applies for stopping
the titration.
(Switch off stirrer) The stirrer is switched off.
Fill dosing
cylinder
After the end of the titration the dosing cylinder is
refilled automatically.
Optional steps are shown in brackets.
