End-point
Target endpoint
for KFT_IPOL* -2000…250…2000 mV
for KFT_UPOL* -200…25…200 µA
The target endpoint defines the measured value which the
titration control is aiming for. The standard settings (250 mV
or 25 µA) are ideal in most cases and should only be al-
tered in exceptional cases. See also page 111ff.
Adjustment
Predefined parameter sets
slow | medium | fast
A selection can be made from three different sets of pa-
rameters for the simplified setting of the titration parame-
ters. Each of these sets includes proven controller settings
which are suitable for most requirements.
slow for low water content or samples which only
release their moisture slowly
medium standard parameters for unproblematic
titrations, optimized for the commonest
applications
fast for high water content of non-critical
samples
If the titration parameters have to be adapted for specific ti-
tration problems the various control parameters can be al-
tered individually.
The [Custom adjust] softkey opens a further dialog
window in which user-defined settings can be carried out
(see page 165).
Meas. interval
Interval between measurement recordings
1…9999 s | off
A measurement point interval must be entered for showing
curves and display of the live value of a
KFT titration. The
measurement data will always be entered in the measuring
point list at these intervals. At the same time the presenta-
tion of the curve and the calculation of the live value are
updated. If the measuring point interval is switched off no
measuring point list will be drawn up.
Temperature
Temperature setting or measuring mode
-170…25.0…500°C | auto | initial
The temperature can be automatically determined during a
titration with the aid of a Pt100/Pt1000 sensor or a com-
bined electrode with built-in temperature sensor. It is pos-
