Evaluation delay
Waiting time until starting the curve evaluation.
Evaluation suppression start
Time from the start of the determination to the start of the evaluation sup-
pression.
Evaluation suppression end
Time from the start of the determination to the end of the evaluation sup-
pression.
Evaluation sensitivity
This value defines the minimum value which the maximum of the curve of
the second derivative has to reach in order to be accepted as a result. The
result, i.e. the induction time, is the time until the first accepted maximum.
The default value "1" will lead to the correct result for most applications.
Smaller values will cause the acceptance of smaller maximums of the second
derivative. Higher values require a higher maximum.
The software suggests a value with which the highest maximum of the sec-
ond derivative is accepted as the induction time. If there is no suggestion
then the highest maximum has already been accepted.
Recalculate stability time
on | off (Default value: off)
Activate/Deactivate recalculation of the stability time. If the recalculation is
deactivated, the original result is kept.
Calculation active
on | off (Default value: off)
If this option is activated, Delta Kappa can be re-entered for the calcu-
lation of the stability time.
If this option is deactivated, the original result is deleted.
Delta Kappa
Conductivity change for the determination of the stability time in µS/cm.
