Stop drift
Volume drift for titration termination
1…20…999 µL/min
After the last addition (…and after the EP has been
reached) the stop drift must be undercut before the ti-
tration can be ended. This volume drift can be inter-
preted as being the dosing rate which is theoretically
required to keep the measured value of the sample so-
lution constant at the endpoint.
t(delay)
Delay before titration termination
0…9999 s
When the EP has been reached the set time is allowed
to elapse before the titration is ended. If the delay time
is set as '0 s' then the titration will be terminated imme-
diately the EP has been reached.
8.6.3 Curve display with KFT
The settings for the curve displays are valid for both the live curve display
and the curve printout. Curve presentation is only possible when a measur-
ing interval has been entered so that the curve is updated each time this
time interval has elapsed.
The representation of the measuring quantities on both axes as well as their
scales can be individually fixed. The presentation of combined curves is
also possible (but not live).
The possible curve display settings for the KFT titrations are the same as
those for DET modes. In addition, curves derived according to time can be
shown, see below.
Quantity Y-Axis
Measuring quantities on the Y-axis
M.value | Volume | Temp. | dMV/dV
dMV/dt |dV/dt | MV,Temp | MV,dMV/dV | all
As well as the standard representation of measured
value/volume other representations are possible. Selec-
tion of measuring quantities on the Y-axis:
M.value pH, mV or µA (depends on mode)
Volume i.e. volume against time
Temp. only for automatic measurements
MV, Temp. measured value and temp.
