off
Measured value acceptance will take place after the maximum waiting
time has elapsed.
Min. waiting time
The minimum waiting period is only important for drift-controlled measure-
ments. The measured value is not accepted until the minimum waiting time
has elapsed, even if the signal drift has already been reached. The drift con-
tinues to be checked while the waiting time is elapsing.
Titrando, 855
Range
0 (slow, optimal, fast) ... 999999 s
Default value 0 (slow, optimal, fast) s
Max. waiting time
If signal drift has been switched off or has not yet been reached, then the
measured value will be accepted when the maximum waiting time has
elapsed. If the waiting time has not been newly entered then a waiting time
that is suitable for the drift will be calculated automatically according to the
following equation:
Titrando, 855
Range
0.1 ... 999999 s
Default value 38.0 (slow), 26.0 (optimal), 21.0 (fast) s
Titrino
Range
0.1 ... 9999 s
Default value 38.0 (slow), 26.0 (optimal), 21.0 (fast) s
Dosing of increments
Note
The following parameters will be displayed only if the User option is
selected in the Titration rate list box.
Volume increment
Small volume increments are used for the determination of blank values or
for very asymmetrical curves. A good guideline is 1/20 of the expected EP
volume. For steep jumps the volume increment should tend toward 1/100
and for flat jumps toward 1/10 of the EP volume. Small volume increments
are used for determining blank values or with very asymmetrical curves. The
accuracy of the evaluation cannot be increased by using smaller increments
