2.6.3 Parameters for KFT
control parameters:
for the EP.
titration parameters
control the general course of the titration.
stop conditions:
Parameters for the termination of the titration.
statistics :
Calculation of mean values and standard deviation,
see page 77.
preselections :
ON/OFF of various auxiliary functions such as auto-
matic requests after the start and activate pulse.

Control parameters
Endpoint (input range depending on the measured
quantity:
U, Ipol: 0.. ±2000 mV
I, Upol: 0...±200.0 µA)
Control (input range depends on the measured
quantity:
U, Ipol: 1...2000 mV
I, Upol: 0.1...200.0 µA)
Outside of the control range: constant dosing, see
page 40.
Maximum dosing rate (0.01...150 mL/min, max.)
sets "max.".
This parameter determines primarily the addition rate
outside the control range, see page 40.
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
Minimum volume increment (0.1...9.9 µL)
This parameter determines the addition rate at the start
and the end of the titration, see also page 40.
This parameter influences the titration speed and
therefore its accuracy very strongly: A smaller
"min.volume incr." results in a slower titration.
