The dialog window Recalculation appears.
2 Adjust the parameters
￭ Activate the options Recalculate induction time and Calcula-
tion active.
￭ Under Evaluation delay and Evaluation suppression start/
end, enter the required values.
￭ Under Evaluation sensitivity, enter the required value.
The software suggests a value with which the highest maximum of
the second derivative is accepted as the induction time. If there is
no suggestion then the highest maximum has already been accep-
ted.
The default value "1" will lead to the correct result for most appli-
cations. Smaller values will cause the acceptance of smaller maxi-
mums of the second derivative. Higher values require a higher
maximum.
￭ Confirm the entries with [OK].
Note
A detailed description of the parameters can be found at "Recalcu-
late induction time", page 120.
