With the

Copy

option in the context-sensitive menu, which is opened by

clicking on the graph with the right-hand mouse key, the displayed ex-

trapolation graph can be copied into the clipboard.

Extrapolation results

The results of the extrapolation calculation are displayed beneath the

graph:

Formula

Exponential equation for calculating the ex-

trapolated time for the target temperature from

the measuring values.

Calculated coefficient

of the exponential

equation.

Calculated coefficient

of the exponential

equation.

r^2

Calculated coefficient of correlation. If this value

is below the

limit

(see below) set by the admin-

istrator then a warning appears when the ex-

trapolation window is opened.

Time

Result of the extrapolation for the target tem-

perature in h and years.

Target temperature

Target temperature for the extrapolation.

Number of determinations

Number of determinations used for the ex-

trapolation.

Standard factor

Value determined from the regression line

which gives the factor by which the time

changes per 10 °C. This value can be entered

in the equation for determination of the

Standard

time

as a

Factor

(see section 4.5.2).

Opens the

Program settings

window with the

Ex-

trapolation

tab for the entry of parameters for

extrapolation (see below).

Updates the display of graph and results after

an alteration in the selection of the determina-

tions in the determination overview.

Shows only the measured values in the graph.
