Parameter description
In the graphic temperature vs. time the linear regression is used to rep-
resent the calculated straight line T = ln(t)/B – ln(A)/B. The measured
values of the selected determination are shown in black, the regression
line in green and the time calculated for the target temperature in red.
Results
Formula
Exponential formula for calculating the time extrapolated from the meas-
ured values for the target temperature.
A
Calculated coefficient A of the exponential formula.
B
Calculated coefficient B of the exponential formula.
r 2
Calculated correlation coefficient. If this value is below the limit value (see
"Setting the correlation limit", page 119) specified by the administrator a
warning appears when opening the extrapolation window.
