2.6.4 Parameters for STAT
control parameters:
for reaching the control point.
titration parameters
control the global course of the titration.
stop conditions:
Parameters for automatic termination of the titration.
statistics:
Calculation of mean values and standard deviation,
see page 77.
evaluation:
Evaluation of rates, fix volumes and fix times.
monitoring
of limit values for the measured value, temperature and
rate.
preselections:
ON/OFF of various auxiliary functions such as auto-
matic requests after the start and activate pulse.

Control parameters
Control point: (input range depends on the measured
quantity:
pH: 0...±20.00, OFF
U, Ipol: 0...±2000 mV, OFF
Upol: 0...±200.0 µA, OFF)
sets "OFF".
Controlling range (input range depends on the
measured quantity:
pH: 0.01...20.00, OFF
U, Ipol: 1...2000 mV, OFF
Upol: 0.1...200.0 µA, OFF)
sets "OFF".
"OFF" means largest control range, i.e. always
controlled reagent addition.
Outside: constant dosing, see also page 51.
Maximum dosing rate (0.01...150 mL/min, max.)
sets "max.".
This parameter determines primarily the addition rate
outside the control range, see page 51.
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
