Target temperature
Target temperature for the extrapolation.
Number of determinations
Number of determinations used for the extrapolation.
Standard factor
Value determined from the regression straight line which indicates the fac-
tor by which the time changes per 10 °C. This value can be entered in the
formula for the determination of the standard time as a factor (see "Cal-
culation of standard time", page 109).
[Settings]
Open the dialog window Program settings. The extrapolation parame-
ters are to be entered in the tab Extrapolation (see ""Extrapolation"
