sible to record the temperature throughout a titration and to
output it as a temperature curve.
numerical
manual input
auto
automatic measurement during the
whole titration (for temperature curve)
initial
one-off measurement at the start of the
titration mode
The temperature can be included in formulas for calcula-
tions (see page 118ff), e.g. for volume corrections. The dif-
ferent system variables are listed on page 148 and 128.
Please note: Start temperature ST and closing tempera-
ture CT are only available with auto.
Time recording
Recording the measurement time
on | off
For recording the titration curve on the time axis the time
recording function must be switched on. If the titration
curve is drawn on the volume axis time recording can be
switched off. This permits smaller determination files as
fewer measurements are made and stored.
Derivation
Recording the first derivative of the titration curve
on | off
If the derivative of the titration curve is to be shown then
derivation recording must be switched on.
U(pol)
Polarization voltage (with KFT_UPOL*)
-1270…400…1270 mV
The polarization voltage is the voltage which is applied to a
polarized electrode during amperometric titration. The re-
sultant measuring quantity is µA.
I(pol)
Polarization current (with KFT_IPOL*)
-127…50…127 µA
The polarization current is the current which is applied to a
polarized electrode during voltametric titration. The resul-
tant measuring quantity is mV.
Stop conditions
The stop conditions define when and how a titration is to be concluded.
Reaching one of the possible stop criteria causes the titration to be con-
cluded. Combinations of stop conditions are possible and may even be ad-
vantageous.
