fer to the numerical measured value alterations. The control
direction can also be determined automatically. The control
direction is then obtained from the initial measured value
and the preset target endpoint.
End-point Target endpoint
for KFC_IPOL* -2000…250…2000 mV
for KFC_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 110ff.
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 different control parameters can be
altered individually.
The [Custom adjust] softkey opens a further dialog
window in which user-defined settings can be carried out
(see page 164).
Fill. rate Buret filling rate
0.01 mL/min…150 mL/min | max.
At the end of a titration the buret is automatically filled. The
maximum value for the filling rate depends on the cylinder
size of the buret used.
Buret cylinder max. speed
1 mL 3 mL/min
2 mL 6 mL/min
5 mL 15 mL/min
10 mL 30 mL/min
20 mL 60 mL/min
50 mL 150 mL/min
