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
